The tab listed seven settings at one weight, each a two-column card with
a heading and a paragraph beside its control. The controls disagreed:
three switches posted on change, while the video model, the crash action
and the guest agent (an Enabled/Disabled select) each had their own
Save, and "From the next start" was repeated under three of them.
Now it has three parts. VM details: title and description with their
Save, and the template switch below them. Devices the guest sees: video,
virtio RNG, TPM 2.0 and the guest agent as rows of name, control and a
one-line note, under one line saying when changes apply; the video model
posts on change and the guest agent is a switch, with its connection
shown beside it as the Power tab's dot. When the guest crashes:
Restart / Stop as two buttons that post on click. Form names, posts and
who sees what are unchanged.
The Turkish catalog now calls the guest agent "konuk ajanı" everywhere.
Each sub-tab (CPU, Memory, Disks) opened on a two-column card that put a
heading and a sentence of current values beside the forms, and the CPU
tab added two more rows: Live vCPUs as a row of "0 · Fixed / 1 · On"
buttons and vCPU hot plug as a select with its own Save.
Now each sub-tab opens on the VM's size. CPU: one cell per vCPU up to
the maximum, filled when on, with "2 on, up to 4" and the host's logical
CPUs; on a running VM with hot-pluggable vCPUs the cells are the
buttons that turn them on and off. Memory: a bar of the current memory
within the maximum, with the host's memory. Disks: a row per disk with
its format, size now and a new size. The forms below keep their names
and posts; the CPU fields are disabled while the VM runs, and hot plug
is a switch that posts on change. A memory or disk resize returns to
its own sub-tab.
A checkbox marked a device as booting and also chose what Up and Down
moved, which moved every checked device at once: to move one device the
others had to be unchecked and checked again. The buttons sat apart
from the rows, and a VM booting by device type got a note that did not
say what to do.
Now the devices the VM tries are a numbered chain, each with its own
up, down and Remove, and the others are listed below it with Add; the
posted order is unchanged. Devices read by kind first (CD-ROM sda,
Disk vda) with their file or network below; a VM booting by device
type says so and how to choose an order. Autostart and the boot menu
sit below, lighter. Focus stays on the device that moved, and on a
narrow screen a device's buttons wrap below its name.
The Turkish catalog says "Ön yükleme" and "sanal makine" throughout,
also in the Power tab texts.
The VM page's thirteen inline script blocks and its inline handlers move
to static files: instance_page.js (tabs, OS details, clone names and
MACs, Add disk dialog, boot order, host devices, migrate plan, console
window, switches that send their form), instance_stats.js (charts and
the Logs view) and instance_status.js (the reload when the VM's state
changes). Their values and messages come as data attributes of the
elements they belong to, page-wide ones on #vm-summary; a form marked
data-please-wait shows the please-wait dialog. Three blocks that did
nothing are dropped: popovers (the page has none), the video model
preselection (the server selects it) and the delete form's poll stop
(that form is on the destroy page). The HTML sink inventory now also
reads the app's own scripts.
A VM made from a template came out at the template's size and shut off,
and was then resized and started by hand. The Clone tab now asks for the
clone's vCPUs and memory, filled in with the VM's, and whether to start
it. After the copy, before the clone is recorded, it is resized with the
Resize tab's own functions and started; a step that fails is a warning
of the job, and the clone stays. The quota counts the larger of the size
asked and the VM's, so a resize that fails leaves the clone at a size it
allowed.
When the job ends the page opens the clone's, not the cloned VM's again:
a template's page, shut off, read as a clone that had not started. An
outcome kept for a warning links to it.
A shut-off VM with TPM state, as every Windows 11 VM, was refused for
migration: the state is a file of the source host, and an offline move
would start it there with a new TPM. Such a VM now migrates as a shut-off
VM with disks to copy does: its UEFI variables are copied, it is started
paused, its CPUs never run, migrates live, which carries the TPM state,
and is shut off on the destination. A shut-off VM with a saved state is
refused before any of that, for every way it moves: started paused, it
would resume and then lose the saved memory.
The clone tab says that a clone gets a new, empty TPM, and the destroy
page that the TPM state goes with the VM.
A VM made without a TPM, a Windows 10 to be upgraded to Windows 11, had
no way to get one but the XML editor. The Options tab has a TPM 2.0
switch, as the RNG one: it adds an emulated TPM of the host's model to
the definition for the next start, or removes it. Its state stays on the
host until the VM is undefined, so a TPM added again has it back. A TPM
the switch did not make (passthrough, 1.2, encrypted, with its own state
path) is left to the XML editor, and a host without swtpm says so.
An existing q35 VM whose PCIe root ports are all used takes no new
virtio disk or network device while it runs, and the only way to give
it more was editing its XML.
The Disks tab of a PCIe machine now counts its slots, "PCIe slots: 0
free of 7", in red when none is free, with what its next start will
have when that differs, and Add PCIe slots adds four root ports to its
persistent definition: libvirt numbers and places them, and a running
VM gets them at its next start. The no-slot advice of Add disk and Add
network device points at it.
The Add disk, Add network device and bandwidth dialogs of the VM page
set their labels in a narrow column beside the fields and closed with
a grey Close: Add disk split "GB" over two lines and offered an
unexplained Metadata box, its existing-volume pool was a dropdown of
links that wrote a hidden field; the network list prefixed every
choice with "Network" or "Interface"; the bandwidth fields asked for
"kilobytes" where libvirt counts KiB/s and KiB.
Now their labels sit above the fields, tied to them, in two columns.
Add disk is one form whose source, New disk or Existing volume, is a
radio card as in the new VM form, the chosen source's fields shown and
sent and its action taken; the size has a GiB suffix and
"Preallocate metadata (qcow2)", the existing volume's pool is a select
that loads its volumes, the bus and the cache are shared. Add network
device picks its
source from Networks and Interfaces groups and says how its MAC is
filled; the bandwidth limit names its units and when a running VM gets
it. Move says when the host has no other pool and is disabled then.
Every dialog closes with Cancel and its action; the posted fields are
unchanged.
The disk Edit dialog showed a disk without a serial as "None" in its
Serial box, so saving it untouched gave the disk the serial "None".
The box and the format box are now empty for a missing value.
The dialog also hid most of its nine fields behind three tabs, said
nothing about a running VM, greyed the bus without a reason and its
switch labels did not toggle them. Now one body shows the disk's bus,
format and size under the title; a running VM's note that the changes
apply at its next start; the path and the Read-only and Shareable
switches in a Source card; the four performance modes in a grid; and
the bus, serial and image format folded under Device, with why the bus
is locked and that changing the format does not convert the image.
Cancel is outlined and Save the primary action.
The Edit dialog of a VM's network device selected the listed network
or interface whose name matched the device's source, and the first one
when none did: saving only a new model moved a macvtap device or a
bridge the host's lists did not show onto the first network, a bridge
named like a network became that network, and a macvtap device chosen
again lost its mode.
The dialog now offers the device's own source first, "<name>, as it
is", and posts nothing for it; the view passes no source and the
device's source element is left as it is. Choosing another source
changes it as before.
The Edit dialog of a VM's network device listed its fields in an
order of its own, named the source list "Net Source" with every option
prefixed "Network" or "Interface", said nothing about a running VM and
closed with Close and Apply.
Now it reads like the disk Edit dialog: the device's model and MAC
under the title, a running VM's note that the changes apply at its
next start, the source chosen from Networks and Interfaces groups, the
model and the NWFilter side by side, the MAC in monospace, and Cancel
and Save. The posted fields are unchanged.
The Network tab gave each network device a card with its buttons in a
footer, two cards to a row, as the disks had.
Each device is now a row of the same kind of list as the disks: eth N
with its target, the source, the IPv4 addresses and the link switch,
and Edit, Add QoS and Delete at the row's end; the device details, the
QoS limits and the macvtap note still fold out below it. A row holds
its Edit and Add QoS dialogs, so only rows sit in the list.
The Disks tab gave each disk a card: its capacity in large type, its
pool, its path and its buttons stacked, two cards to a row, so a VM
with a few disks filled the screen.
Each disk is now a row of one list: the device with its bus and format,
the capacity and the space used with a thin bar, the pool and the path,
and Edit, Move, Detach and Delete at the row's end; the device details
still fold out below it. A qcow2 file whose metadata takes it past its
capacity shows a full bar.
The Resize tab's CPU, Memory and Disk panes were horizontal forms with
bold host figures. The owner chose the ledger layout from three
rendered options: each section with its heading, the VM's figures and
the host's on the left, its fields on the right, and one line on what
applies now and what at the next start.
Codex reviewed resizing end to end; these are fixed:
- A vCPU turned on or off while the VM runs is kept at its next start:
libvirt was asked without flags, which changes the running VM only.
- A paused VM offers to turn vCPUs on only: turning one off needs the
guest, which does not run.
- A smaller disk size is refused, and so is the rest of the form,
before anything grows; it was skipped without a word.
- vCPUs and memory below 1 are refused.
- The memory fields are numbers filled with the VM's values: the
"Custom value" box, its script and the preset list are gone; an empty
custom field silently used the preset.
- Units and words: MiB, not MB; a disk's field is its new size, with
its size now above it; the messages say what the VM gets.
Settings > Users was a bold title, an unlabelled "+" and a table of
names with a trash icon. The owner chose this layout from three
rendered options: one list of owners, each with what it may do
(change settings, delete the VM, change console settings, or power and
console only), Edit rights and Remove, an empty state, and a labelled
"Add owner".
- Remove and Edit rights come back to the VM's Users tab: the return
address carried #users unencoded, so it was lost, and Edit rights
went to the user's account page. Both accounts views now go to a
?next page of this site.
- The add-owner list offers only users who are not owners yet and not
administrators, who can use every VM anyway; a superuser owner also
took the only place when a VM may have one owner.
- The unused del_owner view and URL are removed: the list uses the
accounts page, which asks before removing an owner.
XML:
- An XML edit not saved yet is kept: the page no longer reloads itself
when the VM's state changes, and the browser asks before leaving it.
A state change lost the edit.
- The button that opens the review dialog reads "Review changes"; it
did not save, as "Change" suggested. Closing the dialog gives focus
back to the editor.
Two settings the owner chose to add to Settings > Options after the
page's review with Codex. Both change the persistent definition, so
they are saved while the VM runs and used from its next start.
- Random number generator: a switch for a virtio RNG device fed from
the host's /dev/urandom, so a new VM does not wait for entropy at
boot. Another RNG device, or the panel's with a rate or driver, is
shown as the VM's own and left to the XML editor.
- When the guest crashes: Restart or Stop (on_crash restart or
destroy); libvirt's default, Stop, when the definition has none.
Stop keeps a VM that crashes again and again down for a look. Any
other action is shown and left to the XML editor.
Settings > Options was four forms under bold sentences, most of them
disabled while the VM ran. The owner chose this layout from three
rendered options: one list, each row a setting with its description on
the left and its control on the right: VM details (title, description),
Template, primary video model, QEMU guest agent. vCPU hot plug moved to
Resize > CPU, next to the vCPU counts.
Codex reviewed the four forms; these are fixed:
- Title, description and the video model are saved while the VM runs:
they are in the persistent definition, used at the next start.
- The template flag has its own form and view, set_template, for
superusers and staff, and only for a shut-off VM: a running VM made a
template left the quota while it kept running. Turning a template
back into a VM checks the quota there, and each change is audited.
The title form no longer touches the flag.
- A new video model stays the primary one; the old model's memory and
head settings, which are its own, go with it.
- The agent and vCPU hot plug forms show the persistent definition; they
showed the running VM's, so a pending change looked undone.
- Enabling the guest agent adds its channel only where it is missing:
saving Enabled again failed, and a channel pending the next start kept
a running VM from getting one.
- The agent line tells a VM that is not running, one without a channel,
and a connected or not connected agent apart.
Settings > Clone was a horizontal form with unlabelled checkboxes. The
owner chose this layout from three rendered options: the clone's name
on top, a "Network" card with a new MAC address per NIC, a "Storage"
card with a new volume name per disk, then the optional title and
description and a footer with Clone.
Codex reviewed cloning end to end; these are fixed:
- Every NIC of the clone gets a new random MAC when the form opens.
Only the first did, so a VM with two NICs gave its clone the second
NIC's MAC. Guess MAC is offered for the first NIC only: a name's DHCP
host entry holds one address.
- A VM without a NIC can be cloned: the first NIC's MAC was required.
- The disk name script uses the persistent disks, as the form does; a
disk added pending the next start kept the source's volume name.
- A running or paused VM is not cloned while a copied disk changes at
the next start: the backup copies the running disk, so the clone
would get the old contents under the new definition.
- A derived volume name that does not start with the source's name now
starts with the clone's name and the disk's device, so a second clone
or a second disk does not take the same name.
- Guess for the clone name says when the DHCP file has no free name; it
stopped with a script error.
- The qcow2 metadata preallocation box shows only for a shut-off VM: a
live clone's backup ignores it.
Other users no longer get hidden MAC and disk inputs or the scripts that
filled them: the server derives those values and ignored the posted ones.
Settings > Console was one horizontal form, and on a running VM its
Update button was disabled. The owner chose this layout from three
rendered options: the console type on top, then a "VNC connection" card
(listen address, keymap) and a "VNC password" card.
- The password is changed by an action: keep it, generate a new one,
set a new one or remove it. This replaces the Generate and Clear
boxes and their precedence, and an emptied field no longer removes
the password silently. The pane says whether a password is set; the
form no longer carries the password itself.
- A VNC password takes at most 8 bytes: libvirt refuses a longer one
("VNC password is 9 characters long, only 8 permitted"). Generate and
a new VM's random password now make 8 characters; they made 12, which
libvirt 11 refuses. A set password keeps its spaces.
- Every check is in the form, so a refused save changes nothing; before,
a refused password removal still saved the other settings.
- The settings can be saved while the VM runs: they are in the
persistent definition. A line says the running console keeps its
settings until the VM is shut down and started.
- The console type shown and compared is the persistent one; it was the
running VM's, so a pending switch to Serial showed VNC and a later
save could switch again.
- While the saved type is Serial, the VNC settings are not shown or
taken; choosing Serial ignores the posted VNC settings.
The Boot pane shows Autostart and the boot menu as switches that save on
change, and the boot order as one list of the VM's disks, CD-ROM drives
and NICs: the devices in the order first, checked and numbered, the
others below. Up and Down move the checked devices; Apply order saves.
- The boot menu can be changed while the VM runs: it is in the
persistent definition, so it applies at the next start, as the boot
order does.
- The boot order editor no longer needs the boot menu enabled.
- A VM that boots by device type (<os><boot dev='hd'/>) names those
types; checking devices replaces that order.
- An order is refused while a device the list does not show (a host
device, a floppy) has a boot place, so Apply does not drop it; the
message points to the XML editor.
- An empty order is refused with a message instead of being ignored.
- get_bootorder gives a NIC's full MAC as its target.
- The unused jQuery multiselect plugin is removed.
Settings > Network was a table whose fields were read-only inputs cut
off at phone width, an unlabelled "+", three icon buttons per NIC and
a separate QoS table keyed by MAC. The owner chose card layout from
three rendered options, with the QoS limits folding out like the
device details:
- A card per NIC: a VM's only NIC spans the row, two or more sit side
by side from md. Each has its name and target, the link state as a
switch, its source and IPv4 addresses, and "Device details"
(type, MAC, model, NWFilter, IPv6) in a <details>.
- "QoS limits" in a second <details>, its summary naming the limited
directions: a form per inbound or outbound limit, with Save and
Delete limit, and the units.
- Labelled Edit, Add QoS and Delete in the card footer; "Add network
device" by the heading. The edit and add-QoS dialogs are titled and
labelled, and the edit dialog's fields have labels.
The limits come from each NIC of the persistent definition, so the QoS
table, Instance.config_qos and wvmInstance.get_all_qos are removed.
Settings > Disk was a bold title with an unlabelled "+", a CD-ROM row
in an input group, and a table whose actions were four alike icons.
The owner chose this layout from three rendered options:
- Removable media: each CD-ROM drive a card with its device, bus and
image, the ISO select and Mount (or Unmount), and Detach; "Add
CD-ROM" by the heading.
- Disks: a card each; one disk spans the row, two or more sit side by
side from md, and the device details are capped at 32rem so values
stay near their labels. The capacity large,
the used size, the pool and the source path, the device's settings
under "Device details" (they were in a popover), and labelled Edit,
Move, Detach and Delete (danger) in its footer; "Add disk" by the
heading.
- While the VM runs, "Add CD-ROM" adds the drive on the SCSI bus, and
a SCSI drive can be detached: IDE and SATA drives cannot be plugged
into or out of a running VM, SCSI ones can. Adding a drive was
disabled while the VM ran. One line says so, and why detaching other
drives and detaching or deleting disks waits for a shutdown, instead
of each button alone being greyed.
The forms, their fields and actions are unchanged. The edit dialog of each
disk is titled with its device, and its fields' ids carry the disk's
number: the dialogs of two disks had the same ids, and the title was not
the dialog's label.
- The Host devices tab gives a shut-off VM a PCI device of its host and
takes it back; libvirt binds the device to vfio-pci when the VM starts
and gives it back when it stops (managed). The VM's PCI devices are
listed with whether the running VM and its next start have them.
- A device is offered, and accepted on the server under the compute's
claim, only when it is no bridge of any kind (bridge header, PCIe port,
or of the bridge class: host bridge, LPC), the host has none of its own
network interfaces, disks or graphics card on it (else: bind it to
vfio-pci on the host first), no other VM names it, and every other
endpoint of its IOMMU group is the VM's too or has no driver or
vfio-pci and no other VM; bridges in the group stay with pcieport, and
a member that cannot be read keeps the group. Nothing in the group is
taken implicitly.
- A snapshot revert checks the PCI devices of the snapshot with the same
rules; migration and clones already leave host devices out.
- The add forms of the tab load together, when the tab opens.
- A Host devices tab on the VM page lists the VM's USB host devices, each
once: how it is chosen (its address, or any device of its model), the
device the running VM holds and whether its next start has it; its other
host devices (PCI, SCSI, mediated) are listed for the XML editor.
- Superusers add a USB device of the host and take it back, on a running
VM too. The add form is loaded when the tab opens, as its choices read
every VM of the host; a hub, a device the host has its own disks or
network interfaces on, or one another VM names is not offered, with the
reason, and refused on the server under the compute's claim. A device is
chosen by model when the host has one of it, else by its address.
- A VM without a USB controller is refused; a device is taken from each
definition as that definition describes it.
- A clone gets none of the VM's host devices (the clone form says so), and
a VM with host devices is not migrated. A snapshot revert is refused when
it would give the VM a device another VM names or the host uses.
- A NIC that is a host device is no longer edited or removed from the
Network tab: the XML editor changes it.
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.
Create, revert and delete are one libvirt call each. The pflash-to-rom
loader rewrite, the hand-written block commit and the s1./s2. names are
gone, so UEFI VMs can take external snapshots, a revert keeps disks added
later, and deleting an older snapshot keeps the newer one.
Create refuses what libvirt could not revert or delete later: internal
snapshots on the VM, a saved state, a running snapshot job, disks that
are not files, CD-ROM media, a branch after a revert, and memory without
a running VM or room in the first disk's pool. A disk-only revert keeps
the VM running, paused or shut off; one with memory resumes it as saved.
A revert in the same second as the previous one, which libvirt fails
after stopping the VM, is retried once.
A snapshot the old code took of a UEFI VM saved the loader as rom; its
revert is refused (deleting it still works).
The snapshots tab lists internal and external snapshots separately, can
save memory too, shows running snapshot jobs, and the revert confirmation
names the disks it detaches and that NVRAM is not restored.
131 test modules sat next to the code they test; instances alone had
51 of them beside views.py and utils.py. They move into a
tests/ package per app, and the JavaScript checks into
webvirtcloud/tests/js. Each non-empty tests.py becomes tests/test_views.py;
the empty generated stubs are removed.
Imports of the app's own modules become absolute, paths built from
__file__ go one level up, the live helper is instances.tests.livetest,
and coverage omits */tests/*. The suite discovers the same 960 tests as
before.
