- One searchable card: each secret's type, usage and UUID, whether it is
kept on disk or in memory and private, and the VMs and pools that use it,
linked. A row menu sets its value or deletes it; Delete is disabled while
the secret is in use, and its confirmation says what is not checked.
- One Set value dialog for every secret; its label and help follow the
type (Ceph key, CHAP password, passphrase), and it says a new passphrase
does not encrypt anew what the old one encrypted.
- New secret dialog: the usage's and value's labels and help follow the
type; the value is optional; Private and Ephemeral are switches with help.
As the storage and network pages; plan reviewed with Codex.
- The list is grouped by type (bridges, bonds, VLANs, ethernet; a type
the host has none of is left out), three cards a row, with a search
of their names, MACs and networks (table_filter.js, which now takes
any element with data-search as a row); a card per interface: its link
as the kernel reports it (up green, down grey, another state or
unknown told as such, no red card for a link that is merely down),
MAC, MTU, speed when known, the members it reports and the libvirt
networks that use it, linked.
- An interface's page: an Interface card (type, libvirt's own state
where it manages interfaces, link, start mode, MAC, MTU, speed, STP,
networks using it); on a host whose libvirt changes interfaces, a
card per family with how it is addressed and its addresses; the
members of a bridge, bond or VLAN with their link and speed, or that
none is reported; for a bridge, the running VMs' cards on it,
directly or through a network using it, with their tap and MAC,
linked (wvmInterface.get_vms: one domain listing). Not the bridge's
delay: netcf tells it in seconds, the udev backend in hundredths.
Start or Stop in its heading, Delete in its menu, disabled while it
runs, on hosts that can change interfaces only.
- A host whose libvirt only reads interfaces says so once, with that
it does not tell their addresses, instead of "None" on every page.
- The New interface dialog is one form, as the New pool and New
network ones (choice_dialog.js, radio_card.html): Bridge or
Ethernet, a bridge's member from the devices it can take, an
ethernet interface's device from the ones the host does not define
yet, a static address's fields with its choice; a refused interface,
or one libvirt refuses, opens it again with what was entered; a made
one opens its page.
- networks_by_device maps the libvirt networks to their bridges or
interfaces on the page's own connection.
As the storage pages; reviewed with Codex.
- The list is a card per network: its name with Active or Stopped and
Autostart badges, its type (network_mode: Isolated, NAT, Routed,
Open, Bridge, Macvtap, SR-IOV), its device, and each address with
its DHCP range; a bridge or macvtap network's addresses come from
the outside network.
- A network's page: its heading starts or stops it, the menu sets
autostart and deletes a stopped one. A Network card tells its state,
type, bridge or interface, MAC and what the type does; a card per
address (every <ip>, each with its DHCP range dialog, which libvirt
takes on a stopped network); its fixed addresses of every subnet in
one table, searched, each with Edit and Delete, one dialog adding
and editing them; the VMs whose definition names it, connected or
configured, linked (wvmNetwork.get_vms, one domain listing, a VM
undefined meanwhile left out); its
bandwidth limits where libvirt sets them (not on macvtap or SR-IOV
networks), in KiB/s, from the saved definition with a note that a
running network takes them when restarted; its XML in an accordion.
The page reads the running and the saved definition once each, and
only to render itself: its actions, which all redirect, read nothing
of it first.
- The New network dialog is one form, as the New pool one: the type
as radio cards (the radio_card.html include, now shared by both),
the chosen type's fields only, IPv6 with its box, a bridge or
interface suggested from the host's (get_host_interfaces, not the
bridges libvirt made for its own networks); a refused network or
one libvirt refuses opens the dialog again with what was entered,
the reasons beside the fields and focus on the first.
- What the New pool and New network dialogs share is one script,
static/js/choice_dialog.js: the radio cards show their fieldsets
(data-kinds) and a refused form opens again focused on its first
refused field; each dialog keeps only its own changes.
- The fixed-address dialogs per family go to the page's own dialog.
- The pool list is a card per pool, two to a row, as the host
Overview's Hardware and Software cards: its name with Active or
Stopped and Autostart badges in the header, then its type, its path
(an RBD pool's Ceph pool), its volume count and its space as the
Overview shows it (computes/pool_bar.html, without the name again);
a stopped pool's space is unavailable, not zero.
wvmStorages.get_storages_info gives the path, autostart and percent
used, which computes.views.host_pools computed for itself.
- A pool's page has a Space card (percent, used of size, of what: the
filesystem of its path, its volume group or the Ceph cluster, which
other pools may share; free) and a Pool card (state, autostart,
type, path) instead of a two-column list mixing facts and forms.
Start or Stop is its heading's button; autostart and deleting a
stopped pool are in its menu; the confirmations stay.
- The volume table drops the row number; a volume's capacity and what
it has allocated share a column hidden on a phone; its format is a
badge; its actions are one group, Clone and a menu with Delete,
named for the volume.
- "New pool", "New volume" and "Upload ISO" are labelled buttons
instead of bare green pluses; their dialogs' titles name them.
- The New pool dialog is one form (design reviewed with Codex): the
pool's type as radio cards, as the VM create page chooses its disk
source (their style moves to webvirtcloud.css), one name, and only
the chosen type's fields, the others hidden and disabled.
- A directory's or a share's mount path follows the name
(/var/lib/libvirt/<name>) until it is edited: no default path of
another pool any more.
- ISO images is a directory preset named iso; when the host has an
iso pool, a card links to it instead.
- Ceph offers the host's Ceph secrets by their names, not every
secret by UUID; without one it says so and links the Secrets page.
- LVM asks to agree that the device is erased, the server too.
- AddStgPool checks each type's fields, a name or a path another
pool has, an RBD secret that is not one of the host's Ceph secrets,
and the names "." and "..". A refused pool, or one libvirt refuses,
opens the dialog again with what was entered, the reasons beside
the fields and focus on the first; the audit row for a taken name
stays.
- The state filter is a row of pills, All and each state, counting the
VMs the search finds (the chosen state aside); a state without any is
hidden unless chosen (All never), and a status line tells screen
readers how many VMs match. Every state keeps its pill.
- A labelled "New VM" button replaces the bare green plus; "Find IP"
says "Find IP / MAC", which it finds.
- States are badges; a shut-off VM is grey, not red: it is not a fault.
- A VM's cell holds its name, its title, and for those who see owners
its first owner as a badge, "+N" for the others (named for screen
readers and on hover); the separate user column goes.
- Each row has the same button group for a superuser or the VM's
owners, from the actions the user may use (states.allowed_actions),
all of it disabled on a VM an administrator paused; view-only users
get none. It holds Console, the power action
the state calls for (Start, Resume, Shut down, or Clone for a
template) and a menu of the others (Suspend, Force off, Power cycle),
what does not apply now disabled. The power button is an icon,
named on hover and for screen readers, so every group is as wide and
they line up from row to row; the power cut confirmations stay. On a
phone Console shows its icon only too.
- A grouped host's row has its name, a Connected or Not connected
badge, its VM count and a labelled host memory bar; an unreachable
host's row is table-warning. Its collapse control and the one for
all hosts are buttons, with aria-expanded kept.
- vCPUs and memory hide on a phone in both layouts, and table cells
keep Bootstrap's own padding there: Zephyr doubles it and a list's
last column no longer fit the screen.
- The search read a row's whole text, so a word on a button or in a
state label matched every row. VM rows now carry data-search (the
name, title and owners, and the host in the flat list), and
table_filter.js searches that text when a row has it; the state has
its own filter.
- Nothing matching left an empty table. table_filter.js shows the
page's #no-match while no row does; the VM list's says so and offers
"Clear the filters". A user with no VMs at all is told so instead of
an empty table.
- The grouped list's "#" toggled each host on its own: a host
collapsed by hand opened while the others closed. It now collapses
every host, or opens them all once all are collapsed.
- One alert names every host the panel cannot reach, with why, in
place of one dismissible alert per host; users who see no hosts keep
their own message.
- A host's VM list showed a VM's maximum memory, the Instances page
its current memory: both show the current memory now.
- The owners' users are prefetched with the VMs; the flat list's
Bootstrap 4 font-italic is fst-italic.
- Totals above the list: hosts connected of all, VMs running of all,
vCPUs given on the CPUs, memory given of the memory of the hosts the
panel reads, as cards; the connected count is red while a host is
not.
- A host's name links its overview; its state is a Connected or Not
connected badge (the dot goes), beside a badge of how the panel
reaches it (TCP, SSH, TLS, Socket); its address in monospace.
- A VMs column: the host's VMs, linked to its Instances, and how many
run.
- The vCPUs have a bar like the memory's: running VMs' and shut-off
VMs' vCPUs against the CPUs, amber over 2:1 and red over 4:1 as the
ratio is; the overview's vCPU card shares it.
- The three coloured buttons of each row are one menu: Overview, Edit
connection and Remove from panel (its popper fixed, as the table's
scrolling box would cut it off).
- The four green add buttons are one "Add host" menu that says what
each kind of connection is.
- The table is table-hover; a host the panel cannot reach has a
table-warning row.
- The VM list's power forms (style="display:inline") are d-inline.
- The fields scripts show and hide are d-none, and the scripts add and
remove that class instead of calling jQuery's show() and hide(),
which could not undo it: the custom memory boxes of the Resize tab,
the ISO upload's error message and the clone dialog's metadata row.
- The please-wait dialog's full bar is w-100.
- The create-VM pages' own 56rem width (.create-vm) goes: pages stop
at 960px now, about the same.
- static/css/font-awesome.min.css goes: no page loaded it, no element
used its classes and its fonts were never in the repository.
static/css/signin.css (308 lines) gave the sign-in and two-factor
sign-in pages their own components: a card, input groups, a submit
button, a footer and a status dot, with gradients, a blurred card,
entry and pulse animations, and rules that undid base.html's layout
(its container, its padding) from a "signin-page" class the pages'
scripts put on the body.
The pages are Bootstrap now: a card in the grid's centre column, the
logo a rounded-3 bg-primary block, the fields Bootstrap input-groups
with the password toggle an outline button, the submit a w-100
btn-primary, the footer a border-top line with a rounded-circle dot.
They follow the selected Bootswatch theme like every other page.
signin.css, its body class and its decoration go; so does the footer's
"v2.0.0", a version the panel never had.
The sign-out page (logout.html) was never shown: LOGOUT_REDIRECT_URL
sends a signed-out user to the sign-in page. It goes, with the view's
template name.
Three upstream rules in webvirtcloud.css set every page's layout
against Bootstrap 5.3:
- .container { max-width: 900px } held each page to 900px at any
screen width, below Bootstrap's own widths. Pages now take
Bootstrap's container widths up to its lg one, 960px, and stop
there on wider screens: its xl and xxl widths (1140px, 1320px) leave
the panel's forms and lists too wide;
- .page-header (margins of 5px 5px 20px 20px) put headings 20px right
of the content under them; its 14 uses are mb-3, flush with the
content (one carried Bootstrap 4's mr-auto, now me-auto);
- p { margin: 10px } indented every paragraph 10px from the content
beside it; paragraphs take Bootstrap's own bottom margin.
webvirtcloud.css keeps only what Bootstrap has no utility for: the
page width cap, the XML editor's place and height, the Tom Select
colour fix, the sortable table headers' arrows, the grouped VM list's
collapsed hosts and the charts' height.
webvirtcloud.css still carried the upstream panel's rules for what
Bootstrap 5.3 has as utilities and components:
- the page's bottom space (body padding) is pb-5 on base.html's body,
and the console page no longer has to undo it;
- the VM page's action tabs (.action-button, .action-block with a
fixed 65px width) are text-center with a d-block icon; its tab panes
(#power ... #undefine, one rule each) mt-3;
- the bordered sub-tab panes (.tab-pane-bordered, a fixed #eee border
that dark themes could not change) border border-top-0 p-3;
- the search box and header buttons (.search, .btn-header) m-1 and
mt-1; the SSH key select (.keyselect) a form-select;
- the boot order list (.multipleselect, fixed size, #c0c0c0 border) a
list-group of form-check-input items; its unused .multipleselect-on
goes;
- table cells centred by a global rule are align-middle on each table.
Two rules against Bootstrap's behaviour go: menus opened on hover on
wide screens (Bootstrap opens them on a click, and keyboard and touch
users had no hover), and "a { outline: 0 }", which hid the keyboard
focus ring.
The paragraph and page-header margins and the 900px container stay
for a separate change: they set every page's layout.
The fork's own rules in webvirtcloud.css redid what Bootstrap 5.3 has:
- the capacity bars (.cap-*) are Bootstrap progress bars: the memory a
.progress-stacked of running VMs' memory and shut-off VMs' (at half
opacity), each segment a progressbar with its amount as its value
text; the pool bars a thin .progress. The line where the host's
memory ends goes: the share above the bar says it, red when over;
- the status dot (.compute-dot) is a rounded-circle, the big figures
(.compute-ratio) fs-4, the Computes table's cell padding py-3;
- the steps of creating a VM (.create-steps) are a breadcrumb with "›"
as its divider;
- the XML and Advanced disclosures (.disclosure with a turning chevron)
are Bootstrap accordions;
- the chosen volumes and networks (.row-list) are list-unstyled, their
names text-break;
- a chart's container is position-relative by utility; its height stays.
Dead rules go too: .netIN, .netOUT, .diskRD, .diskWR, .input-xs and
.bottom-bar-margin had no users.
The memory given read "24.0 GB given of 32.0 GB": long, and the share
of the host's memory, what one looks for, had to be worked out. It is
now told as the vCPUs are: the share large ("75 %", amber over 90 %,
red over 100 %), then "24.0 GB / 32.0 GB", the bar and "12.0 GB
running". The Computes list's memory column shares it.
Every card of the overview has a Bootstrap card-header with an icon:
VMs, vCPUs, Memory, Storage, CPU in use and Memory in use (with the
current reading at its right), Hardware, Software and connection. The
last two were label and value lists under indented headings; they are
list-group-flush rows now, the label at the left, the value at the
right: counts in semibold, the hypervisor's and libvirt's versions as
badges, the guest architectures as light badges, the emulator and the
connection as code. The section headings, indented by the panel's
page-header margin unlike the cards, are gone: each card names itself.
The status line and notes are not paragraphs, which the panel indents.
A host the panel could not reach made its overview the 500 page,
without the host's sections, and the Computes list gave such a host an
Overview button that led nowhere. The page now keeps the host's name,
sections, "Edit connection" and "Remove from panel" (the existing
confirmation), and says "Not connected" with the reason and a "Try
again". Details that cannot be read are said in an alert; the VMs,
capacity and load still show, as they are read on their own.
A reachable host's page leads with what it runs and what it gave:
- its VMs by state (running, shut off, paused, other), linked to
Instances;
- the vCPUs, memory and storage pools given, as on the Computes list,
which now shares those parts (computes/capacity_*.html) and their
preparation (views.shown_capacity) with it;
- CPU and memory in use, side by side, with the current reading in
words, a note on what the charts hold and when they were last
updated, or since when not; memory in GB like the rest of the page;
- Hardware and Software and connection: logical CPUs and clock from
virNodeGetInfo, but physical cores, sockets and NUMA nodes counted
from the CPUs of the capabilities' NUMA cells, as virNodeGetInfo
makes a topology up for hosts it cannot describe (asymmetric NUMA);
the hypervisor's own name and version, libvirt, emulator, the guest
architectures as text instead of menus of dead links. A host without
sysinfo shows no processor instead of failing.
Empty notes no longer show "None"; labels stack over their values on a
phone instead of running into them.
Pools that cannot be read no longer drop a host's vCPUs and memory from
its capacity: the storage part says so. get_capacity also counts the
VMs by state.
A key held from the menu (Hold Ctrl, Alt or Windows) is the same key as
the keyboard's left Ctrl, Alt or Windows key. Pressing and releasing
that key on the screen let the VM's key go, while the menu still showed
it held. And when the key went down outside the screen (in the
Clipboard dialog) and came up on it, noVNC sent no release, as it had
not seen the key go down.
The release of that key where noVNC takes keys (the screen, the touch
keyboard) now lets a held key go itself, and clears the menu's mark. A
release elsewhere reaches no VM and changes nothing.
"Type it" sent each character's keysym and let QEMU pick the key from
its own US map, with Shift added for the US shifted characters. A VM
on another layout got other characters: on Turkish Q, '"' typed 'İ',
'@' typed "'", and ğ, ü, ş, ı, ö, ç typed nothing.
The Clipboard dialog now asks for the VM's keyboard layout and
remembers it per browser. Each character is typed as the key that makes
it on that layout (its scancode), with Shift, AltGr or both (AltGr
first: pressed after Shift, the right Alt is Alt on the Linux console),
so the VM's own layout makes the character. The layout is fixed when
typing starts. Text with a character no key types on the layout is not
typed at all, and the dialog lists those characters: a password or a
command with a character left out would be a wrong one.
A layout is one file in console/layouts/: its name and, for each key,
the characters it types plainly, with Shift, with AltGr and with
Shift+AltGr. The view offers every file, US first. dev/console_layout.py
writes a file from the system's XKB data as libxkbcommon computes it
(through ctypes, no new dependency), mapping keys to DOM codes with
noVNC's table from QEMU's keycodemapdb; it lists the dead keys it leaves
out, and drops the keys the keyboard model lacks (the key left of Z on
US pc104 keyboards). English (US) and Turkish Q come with it; the
README says how to add one.
The serial page had a white strip of inline styles with an untranslated
status and a browser-default button above the terminal, sent input while
disconnected, sized the terminal only on window load and resize, and left
the keyboard elsewhere after the key menu. When a superuser opened a
console open in another window, its user saw "[An administrator opened
this console]" and a plain "disconnected".
- console-xterm.html shares the VNC page's bar: status badge (Connecting,
Connected, Disconnected, the server's refusal), Disconnect, then
Reconnect (a new page for a new token). The script is
static/js/console_serial.js; the token reaches it as json_script data.
- The terminal takes the keyboard on connect and after the key menu; input
is sent only while connected; it fits its box on connect and whenever
the box changes size (ResizeObserver).
- A console that writes nothing yet gets a dim local hint: press Enter.
- socketiod sends the displaced client "taken_over" with the superuser's
username; the page shows "Taken over by <name>" in the bar and the
terminal. The superuser is not asked first (owner's decision).
- Fullscreen uses the shared console_keys.js handler (keyboard lock).
The VM page offered a lite and a full VNC console. Lite lacked a clipboard,
display settings and a way to reconnect; full put noVNC's own side bar under
the panel's bar, with a Fullscreen item that called a function noVNC does
not have, status messages hidden behind the bar, saved noVNC settings that
overrode the Access tab's, connection settings that cannot apply, and a
Connect button that reused the page's two-minute token and failed.
console-vnc.html and static/js/console_vnc.js replace both, on noVNC's RFB
with Bootstrap controls, and keep what the full view did:
- Status in the bar (Connecting, Connected, Disconnected, Connection lost,
Could not connect, Authentication failed with the server's reason on
hover); Disconnect, then Reconnect, which loads the page again for a new
token.
- The VNC password in a dialog (with a username when the server asks for
one), not a browser prompt; without passwordless console it is not in
the page.
- Send key(s) gains Hold Ctrl / Alt / Windows (noVNC's extra keys).
- Clipboard: what the VM copies, sending text to the VM's clipboard, and
typing it key by key (new: works in firmware, installers and login
prompts; Shift for the characters a US keyboard shifts, 25 ms a key as
firmware drops faster keys, verified in a UEFI shell).
- View: scaling (none, fit, resize the VM's screen), clip, drag a clipped
screen, view only, dot cursor, quality, compression; it starts as
Settings > Console says (a touch screen starts fitted).
- A Keyboard item on touch devices (noVNC's on-screen keyboard input,
key events and Android's text-only input), Fullscreen with keyboard
lock, the bell.
Dropped with the full view: noVNC's websocket host/port/path, repeater ID
and log level (the panel fixes them), automatic reconnect (the token is
single use in time), XVP power buttons (QEMU has no XVP) and shared-mode off.
The bar is compact (about 45 px in the 850x600 window). The Access tab has
one Console button instead of the Lite/Full split and four switches, and
it and the VM list open one window per VM (opening it again reloads it).
The lite and the full console page each carried the same 150 lines that
send key combinations (Ctrl+Alt+Del, Ctrl+Alt+F1..F12, Alt+Tab, ...). They
now import static/js/console_keys.js, which binds the menu to the page's
RFB connection.
The list pages' search (filter-table.js) read what was typed as a
regular expression: a "(" or "[" stopped it with an error. It also
needed jQuery, while the instance list had its own script for the same
search. Both are now static/js/table_filter.js: plain text in any case,
the instance list's state list and host groups where a page has them,
remembered for a day as before. A group's header row is marked as one
(data-group-header) instead of being any row without a state.
The dialog filled its texts with String.replace, which reads $& and $'
in the replacement as patterns: a host named c$&1 showed as
c%(hosts)s1. The values now go in through a function, which inserts
them as they are.
Each host is a row of what it has committed, read live from the host (in
parallel, by a 10 s deadline):
- Host: a status dot, the name, its address and details; when it cannot
be reached, why.
- vCPUs: the overcommit ratio, large (warning above 2:1, red above
4:1), over "N vCPUs on M CPUs" and the running VMs' share.
- Memory: memory given to all VMs against the host's memory, as one bar:
running VMs dark, shut-off VMs light (they take their memory again
when they start), and a line where the host's memory ends; red when
the VMs were given more than the host has.
- Storage: the default pool (or the first) with its used share and free
space; the others, a host may have dozens, open on a click.
A host that cannot be reached, or does not answer in time, says so in
one line instead. vCPUs and Memory sort by ratio and share. A host whose
read hangs is not read again until that read ends, so a stuck host keeps
at most one thread. The table's hidden status texts stay inside it, so
the page does not widen on a phone.
The search's request was sent on to the login page, and the dialog said
"The search did not go through. Try again." The page now reloads, which
goes to the login form and back to the Instances page after signing in.
The "Find IP" dialog takes a MAC address (aa:bb:..., aa-bb-... or
aabb...) as well as an IP address or a network. A MAC finds the VMs with
a network card of that MAC, shut-off ones too (from their definitions),
with that card's addresses when the VM runs: for a MAC seen on a switch
port or in an external DHCP server's log. A MAC on more than one VM is
marked as a possible conflict. Only the VMs with that MAC are read, and
the card's link-local address, which comes from the MAC, is left out.
The Instances page's filters and the address search become one control:
the state list, the search box and a "Find IP" button. "Find IP" opens a
dialog (with the address typed in the search box, if any). An IP address
or a network (CIDR) finds the running VMs whose network cards use it,
read live from libvirt within 5 seconds: libvirt's DHCP leases, the host's
ARP table and the guest agent. Only addresses on the VM's own NICs count,
so interfaces inside the guest such as docker0 never match. Each match
shows the VM, its MAC, where the address came from, and a possible-
conflict mark when two VMs report one address. A coverage line says how
many running VMs were checked, how many had no connected guest agent (a
static address on them cannot be seen), which agents could not be read,
which hosts were not reached or not finished in time, and when it was
read.
The hosts are read in parallel: leases and ARP first, then each guest
agent on its own thread, so an agent that never answers holds back only
its own VM; libvirt waits for an agent without limit, so a search starts
only while its threads fit in 16 search threads in the worker.
Administrators search every compute, VMs the panel has not registered
yet included, and see the hosts; other users find only their own VMs and
see no hosts or host errors.
Found by review (Codex and agy) of the XML editor's dialog:
- A busy or moved VM made the page reload and the edit was lost. The
dialog's requests now get these answers as JSON (X-Requested-With, as the
create page's flavor forms) and show them; any other failure says the
edit is still in the editor.
- libvirt finds the VM to define by the XML's UUID: another VM's UUID
overwrote that VM past its lock, a new or missing one added a VM. The
XML must keep this VM's UUID; a malformed one is refused with the
parser's error, as on the create page.
- Save sends the XML whose diff the dialog shows, also when two previews
answer out of order; a failed save keeps the diff and Save.
- The edited XML is defined with the line breaks libvirt gave, not the
form's CRLF, and the VM's state is read before the definition, so a
failed read cannot turn a saved change into an error.
The XML editor of a running or paused VM only showed its XML. It now
shows the persistent definition, the one the VM starts with next (with
secrets, like the other edit forms), and Change saves it through the same
review dialog; the running VM keeps its live configuration until it
restarts. The tab and the saved message say so. The check against a
definition changed since the editor was opened covers this case too.
Change used to define the edited XML at once. It now opens a dialog with
the lines the edit changes in the VM's definition, and Save there defines
it. A definition libvirt refuses comes back to the dialog with the reason,
and the edit stays in the editor; before, the page reloaded with the
current XML and the edit was lost. A definition that changed since the
editor was opened (another tab, a disk added) is not overwritten: the
dialog asks to reload. An unchanged XML has nothing to save.
change_xml answers the dialog with JSON; the editor's script moves to
static/js/xml_editor.js.
sortable.js 0.8.0 (abandoned since 2014) sorted only a table's first
body: in the grouped VM list the first host's row moved among its VMs
and the other hosts never sorted, and memory sorted as text ("1024 MB"
before "512 MB"). tablesort 5.7.1 sorts each table body on its own and
keeps a row marked data-sort-method="none" in place, so hosts stay in
name order with their row on top and their VMs sort below it. Memory,
vCPUs and volume sizes sort by their numbers (data-sort). Headers are
reachable by keyboard and carry aria-sort.
base.html loads tablesort for every table marked data-sortable; the
per-page sortable includes and sortable-theme-bootstrap.css go, so these
tables take the theme's table style like the others. The grouped list's
row numbers go (meaningless once sorted). The VM owners and VM logs
tables were marked sortable but never loaded the script; they stay
unsorted.
The list gets a state selector beside the search box. The search now
matches plain text in any case (a '(' no longer breaks it), and in the
grouped list a host's name shows all of its VMs while a host row shows
only while one of its VMs does. The filter moves to
static/js/instance_filter.js with a Node test; the other lists keep
filter-table.js. Collapsing a host now sets a class on its table body
instead of each row's display, so a collapsed host and the filter no
longer undo each other.
The create page had three tabs (flavor, custom, template), each with its
own copy of the same create form; every flavor rendered one more copy in
a dialog, and fixes had to be made in each copy. All of them posted the
same form to the same job, differing only in where the disk comes from.
The page is now one form in sections: name and size, disk, networks and
an Advanced section. The disk section offers three sources as radio
cards (a new disk, existing volumes, a copy of a template); only the
chosen source's fields are shown, and the others are disabled, so they
are neither sent nor validated. A template's copy goes into the
template's pool unless another is picked. Flavors are presets that fill
vCPU, memory and disk size and pick a new disk; they are added and
deleted in a dialog outside the form. Every source uses the
per-interface network rows, so a new disk no longer requires a MAC:
libvirt gives an interface without one its address, as it did for the
other sources. A refused form comes back with its source, volumes,
template and networks, and the focus on its first error. Without a
storage pool or a network the page shows why instead of the form, and a
host that cannot be read is a message, not a 500.
The host dialog and the machine page share the form's look: hosts are
rows with their CPU and memory use, the machine page is a card with
Cancel/Next and the XML way is a collapsible section. All three steps
show the same step indicator, done steps linking back.
The create job refuses more than one disk source (the page sends one; a
crafted request could send two, and the job would have used the first).
A field with help text is described by its help and its error.
Frontend review fixes: the presets and the disclosure buttons show a
focus ring for keyboard users; a disclosure spans its card and its
chevron turns while open; a preset says it picks a new disk; numeric
fields bring a numeric keyboard and MAC fields no autocorrection; the
machine page's Next waits for a machine type. Tom Select's control
keeps the text colour of the select it replaces: its own fixed colour
made typed text invisible on dark Bootswatch themes, on every page that
uses it.
Column offsets without a breakpoint applied below it, where the column
is already full width, so the change password, compute, user, VM
create and VM settings forms ran past the right edge on a phone. Each
offset now starts at its column's breakpoint. The interface and network
detail lists were rows directly inside rows and sit in a column now;
the compute form loses a Bootstrap 3 thumbnail padding that broke its
gutters, and the add-rule dialog's hint is no longer cut off. The page
test checks both grid rules on every page.

Rendered through every URL on libvirt's test driver, the pages had
duplicate IDs and markup browsers repaired silently:
- Each flavor modal's "Advanced" button toggled #flav-add-collapse, the
first modal's section; every modal now has its own. The flavor and
template copies of the custom tab's control IDs, and the template
tab's unused images input, are gone.
- The VM page's action icons and the XML editors were styled by
repeated IDs; they use classes.
- Modal forms opened inside modal-body and closed after modal-footer;
they wrap both. Stray end tags and duplicate attributes are removed,
paragraphs no longer hold modals or rows, table heads have a row, and
the create page closes its row and column.
- html lang is the active language instead of "en".
A test walks every URL as a superuser and fails on a repeated ID. The
console page still has no doctype: its full-height layout relies on
quirks mode and needs its own check.
A theme change compiled Bootswatch with libsass (34 MB, upstream
deprecated) into two tracked files, which updates, rollbacks and new
Docker containers then reset. The 27 themes now ship as
static/css/themes/<theme>.min.css, built by "manage.py build_themes";
the Settings page only saves the theme name and every page links that
file (zephyr when no settings are in context, as on the 500 page).
libsass moves to dev/requirements.txt; a test checks that each shipped
file is its theme compiled from dev/scss. The "Theme SASS Path" setting
is removed, and the theme default "flaty", a typo that never applied,
becomes zephyr, the theme those installs showed. The update and
rollback steps restore an older version's rewritten theme files only
where they are modified.
@xterm/xterm 6.0.0 and @xterm/addon-fit 0.11.0 replace xterm 3.6.0; the page reads typed and pasted input with onData, and no longer writes every key and all terminal output to the browser console. The unused fullscreen addon goes.
The create wizard's image and network pickers use Tom Select 2.6.2 (its
Bootstrap 5 theme and checkbox list), which does not need jQuery;
bootstrap-multiselect calls $.isArray, which jQuery 4 removed. The
selected images and networks still fill the wizard's own lists.
Bootstrap SCSS, the JS bundle and the Bootswatch themes go from 5.3.3 to
5.3.8 (bug fixes only), and wvc-main.min.css is recompiled from zephyr.
Bootswatch now gives table text the body color, and Lux drops card and
modal header borders.
Tests compile every theme with the pinned libsass and check that the
shipped CSS is zephyr from these sources. The update and rollback steps
put back the two files a theme change rewrites, or git refuses to pull
over them.
Each stats answer carries a signed sample of the counters, bound to the VM,
its compute and UUID. The next poll sends it back and the rates are the
averages since then; a sample from another run of the VM (domain ID),
another host CPU count or device list, or older than 30 s falls back to
one second as before. Windows are measured on the monotonic clock.
Now that a poll is cheap, the Stats tab polls every 5 s like the host
graph, the first time as soon as it opens (pollWhileVisible takes the
delay of the first request).
A counter the host reports as unsupported (-1) or that went back gives no
value instead of 0 or a jump; a NIC without a target keeps its chart, a
pool volume disk is measured, and a disk or NIC attached after the page
loaded no longer stops the other charts. Disk rates are MB/s (they were
MiB/s labelled Mb/s), network Mbit/s; the CPU tooltip names the window.
Redirects to #access (root password, SSH key) and other top-level panes
opened nothing, and some sub-tab ids did not exist. static/js/instance_tabs.js
opens the pane and the tab that holds it from the page structure, and
opens Settings on its first section, without leaving the current tab;
guest OS info is loaded whenever it is the section opened. The bottom bar linked to
host pages, which only administrators may open, and showed host names to
everyone. A stray </li> is removed; the page's inline scripts and the tab
logic are checked with Node.
django-bootstrap-icons serves icons from static/icon_cache and fetches a
missing one from the CDN while the page renders; a server without
internet access shows an error text instead of the icon.
- copy (Clone on the instance lists), envelope-open ("Lost OTP?" page)
and save (VM settings, network page) were not cached; they are now,
fetched with django-bootstrap-icons itself.
- The user and group lists asked for 'exclamation-triangle ' with a
trailing space, an icon that does not exist; the warning icon never
showed.
A test checks that every {% bs_icon %} in the templates has its cache
file; it fails on the previous files.
The VM page polls the VM state every 5 s and, while its Stats tab is
open, the statistics every 10 s; the compute overview polls the host
graph every 5 s. All used setInterval:
- A new request went out on schedule while the previous one was still
open. When a host goes silent, a stats request waits up to 30-45 s,
so each open page held several sync workers at once.
- Each time the Stats tab was shown, the page made new charts and a
new interval without stopping the old ones, and polling went on on
the other tabs of the page.
- Hidden pages kept polling at full rate.
Measured in a browser against a test server (old code / new): Stats tab
shown 4 times, 31 s on it: 12 / 2 requests; 31 s on another tab of the
page: 12 / 0; page hidden for 31 s: 15 / 0, and the new code asks once
right after the page is shown again; with 25 s answers, at most 15 / 1
requests open at once.
static/js/poll.js repeats a request while the page is visible: the
next one 5 or 10 s after the previous answer, none while hidden, one at
once when shown again. The Stats tab makes its charts once and polls
only while shown. The answer handler runs after the poller's own
bookkeeping, so an error in it (a chart for a disk added meanwhile)
does not stop the polling. A Node test of poll.js runs with the test
suite when node is installed.
- Replace hardcoded colors with Bootstrap & Bootswatch CSS custom properties
- Adapt background, card, borders, and inputs dynamically to active light and dark themes
- Inherit primary color, border-radius, and font-family from active theme
- Use native Bootswatch alert and button styles for consistent visual hierarchy
