- The root password's SHA-512 crypt hash comes from libpass (the maintained
passlib fork, pure Python) instead of crypt-r, a copy of the stdlib crypt
module gone in Python 3.13: crypt-r ships no wheels and its build needs
crypt.h, which Ubuntu 26.04 no longer brings with python3-dev, so the
installer and the manual installation failed there. The hash is the same
format ($6$, now with libpass's 656000 rounds), checked with glibc's crypt.
- The README's RHEL compute packages left out python3-libguestfs, which
gstfsd imports with the system python: setting the password or key of a
shut-off VM failed there.
- The tests read YAML themselves and had PyYAML only through
drf-spectacular.
- The VM list with no VMs no longer also says that no VM matches the
search and the state.
- The New VM dialog with no compute yet says to add the first host, with a
link to the Computes page (and links there when none is reachable).
- The new VM page on a host without a running storage pool or a network
says what to add or start and where, instead of "You haven't defined any
storage pools" (also when pools exist but are stopped) and "network
pools".
A running VM's page read its addresses while it rendered: the guest agent,
when its channel is connected but it does not answer, holds the page (and
a gunicorn worker) for its whole 10 s timeout, on every load. The page now
shows them once it has loaded: vm_addresses.js asks the new
instances/<pk>/addresses/ for each NIC's addresses and fills the header's
IPv4 and each network card's IPv4 and IPv6.
English-only texts users read, now in their language:
- the serial console's four refusals, which socketiod sends in the
language LocaleMiddleware would choose (cookie, then browser) and logs
in English; the texts live in console/refusals.py, as makemessages
reads only .py files;
- a submission key reused for another request, a malformed MAC address,
the moved-VM refusal of a script's request, the API's "Templates
cannot be started" (now the page's sentence), "Pool is not active"
and the ISO upload's checks;
- "Problem occurred with host" was a fragment with the host's name and
error after it: one sentence with both.
The root password hash for a shut-off VM used crypt_r where installed
(Python 3.13) and fell back to the stdlib crypt, which Python 3.11 and
3.12 deprecate: `python -W error::DeprecationWarning manage.py check`
failed there. crypt-r (the same module, it requires Python 3.11) is now
installed from 3.11, and the module is chosen by the Python version;
3.10's crypt is not deprecated.
Each was checked with git grep across every tracked file (templates, JS,
shell, unit files and the extensionless console daemons) and for
dynamic use (URL names, template names, registries):
- vrtManager: host_is_up, is_kvm_supported, get_emulators,
get_file_extensions, both get_network_forward, get_snapshots,
get_storages_images, get_os_type, get_host_arch, the get_pretty_* trio
and, in util, is_kvm_available, randomMAC, get_max_vcpus, compareMAC,
pretty_mem, pretty_bytes and validate_uuid; with them the port
constants only host_is_up read. Some were reached only by their tests,
which go too.
- The flavor edit page: nothing linked to it; flavors are created and
deleted on the Flavors page and edited through the API.
- computes.validate_name, UserForm.identity_has_errors, the has_perm
template tag, the ALLOW_EMPTY_PASSWORD setting nothing reads,
hidePleaseWaitDialog, default_app_config (ignored since Django 4.1)
and the Python < 3.6 lines of secret_generator.py.
The delete ran in the request: undefine, then the VM's record, then its
disk files. A request that died in between (a gunicorn worker past its
timeout, OOM, a restart), or a database write that failed after the
undefine, left a record that later showed as removed outside the panel,
and the disk files the user asked to delete were never deleted.
Deleting a VM is now an instance.delete job. It holds the compute
exclusively, as the request did, so no other VM attaches a file it is
about to delete. The job chooses the files before it stops the VM (a host
that cannot be checked still stops nothing) and records them first. It
then stops and undefines the VM, removes its record, and deletes the
files, each with its own Logs row. Recovery decides from libvirt: a VM
still on its host means the delete failed; a VM gone means libvirt did
it, so recovery removes the record and deletes the recorded files that
are still there.
The page queues the job and returns to the VM page, where the job panel
follows it and opens the VM list when it ends; disks that were kept are
the result's warning. The API's delete answers 202 with the job and
needs a submission_key. backing_path moves to wvmConnect, as recovery
has no domain to ask.
A CD-ROM form sent twice (a double click, a resent request) added a
second drive with the same ISO. The form is refused when the ISO is in a
CD-ROM of the VM's running or persistent definition; an empty drive may
still be added more than once. tr and zh too.
A drbdadm query that timed out, could not start ssh or failed showed
"None DRBD", as for a VM without DRBD resources. It now shows Unknown,
in the same red badge as a DRBD status that is not OK.
Every connection got a thread before any authentication, and every
signed request a guestfs appliance, with no limit: with remote access
allowed, anyone on that network could make the host run out of threads
or memory. A connection over MAX_CLIENTS (4) now gets an unsigned busy
line and is closed before it gets a thread; the panel shows it as the
gstfsd error.
No view used sensitive_post_parameters, so once ADMINS is set the error
mail of a failing POST would carry the password or key in plain text.
The user create, edit and password views, the password change, the
compute forms, the host secrets, the VM's root password and its console
settings now mark their POST data sensitive.
The page checked only that the VM's host answers; a VM undefined with
virsh then failed at its first read and the page was a server error. It
now says the VM is no longer on its host and goes back to the list, whose
sync forgets the record (tr and zh too).
It looked the user's ownership up by the VM's name on its compute; names
are not unique there (a VM renamed outside the panel and a migration can
leave two), which gave a server error or another VM's rights on the page.
The VM and compute claim decorators checked only that the user sees the
VM, took the claim, and left the action's own right to the view inside:
a read-only viewer, or an owner who may not delete the VM, briefly held
the VM's or the whole compute's claim and could make other requests
there busy. They now check the least right first: power for a VM change,
delete for the compute-wide claim (destroy; its other views are
superuser-only).
The list page synchronised and connected to every compute for every user,
while the poll and the API list read only the hosts of the user's own VMs.
Hosts a user has no VMs on no longer get a listing per page load, which
also took one of their request slots.
A web request refused because this process's requests to the host
(HOST_REQUESTS) all still wait for it raised the same ConnectionFailed as
a host that is down, so the VM page said the host cannot be reached. It
now raises HostBusy; the VM page and the error users who do not see hosts
get say the host is busy and to try again in a moment.
libvirt takes the same disk file or MAC twice in a persistent
definition. A double click or a resent request then attached an
existing volume twice, and a shut-off VM did not start again (QEMU
opens no file twice for writing), or added a second NIC with the MAC
the form had filled in. Attaching a volume that is already a disk of
the VM, live or in its next start, and adding a NIC with a MAC the VM
has are now refused with the reason.
gstfsd_request connected with the 120 seconds it waits for the change:
a host that was down held the request's thread two minutes before its
page said so, a wait no host bound counts. It now connects within
libvirt's CONNECT_TIMEOUT and gives the change its 120 seconds after.
607c8381 sent each memory and disk resize back to its own sub-tab, but
the disk view's last redirect, the one after a resize was tried, still
went to #resize, which opens on the CPU sub-tab. Only the live tests
reach it, with a disk to grow: the full live suite failed there on every
connection type.
The live vCPU test built its post from the page's form, and the page now
disables the CPU fields while the VM runs, so the post lacked cur_vcpu
and was refused as not a number before the running VM was. It now posts
both fields, as the direct post it checks.
The VM's keys page (instances:sshkeys) and the cloud-init user data
collected the owners' keys with one query an owner. Both now read them
in one query joined over the VM's owners, ordered owner by owner as
before.
A VM list row showed the VM's state, memory, vCPUs and title, read
through the VM's own connection object: a lookup by UUID, virDomainGetInfo
and the live XML, one after the other for every VM on the page.
The lists (Instances, grouped or not, and a compute's VMs) now read each
host once: the states in one getAllDomainStats call (the state group
only, as the lists' poll; no other group, so a VM busy in the QEMU
monitor holds nothing up) and the memory, vCPUs and title from each
VM's live XML, which the title already read. Checked on QEMU against
virDomainGetInfo for running, paused and shut-off VMs: the same values.
A VM gone from its host, or a host that cannot be read or fails its
listing, shows its VMs unknown as before. Only the grouped list, a
superuser's, prefetches every host's VMs and owners.
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.
The Resize tab offered vCPU counts only up to the host's logical CPUs.
A VM whose maximum was higher (4 on a 2-CPU host, say) found no option
for it, so the Maximum list showed 1, and a resize of the shut-off VM
lowered its maximum to that without a word.
get_max_cpus() now takes the VM's own maximum as a floor, and the
Instance's vcpu_range passes it. The host's CPU count shown on the page
and used by the clone form is read from the host alone, not from that
range.
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 tab put Power Off and Suspend, then Power Cycle and Force Off, in
joined button groups with a paragraph under each, so which sentence
told which button was left to the reader, and the two power cuts
looked like one control as large as the rest.
Now the tab shows the three states a VM moves between, Active,
Suspended and Off, the current one marked, and under each the action
that takes the VM there with one line on what it does. The power cuts
are small outlined buttons on a line of their own with one warning;
their confirmations stay. A state outside the three (shutting down,
crashed) is named above them. The test of the tab now finds the
outlined power-cut buttons, which its class match missed.
A quota refusal put the English name of the quota (cpu, memory, disk,
instance) into a translated sentence, so a Turkish page read "memory
kotası doldu". check_user_quota now returns which quota and its numbers
(QuotaExceeded), each quota has a whole sentence, and the refusals put
that sentence before what is refused; QUOTA_DEBUG adds the numbers as
before. The clone job stores the refusal as a message, so the Jobs page
shows it in its reader's language.
The connection errors of vrtManager (did not answer within, still
waited for, closed, failed with libvirt's text) were English f-strings;
they are messages now, each close reason a whole one. A connection
that died without a close callback raised an error reading "None"; it
now names the host. Logs keep the English text.
vrtManager's errors (some 140: a disk that does not move, a network
address outside its subnet, a host device given to another VM, the
disks a migration cannot copy) were English f-strings, so no catalog
could translate them, on pages or in jobs.
They are marked texts with their values now; a variant that differs by
a word (internal or external, running or persistent, with a subnet or
without) is a whole message of its own, and a list of problems is a
list of messages. OperationError reads in the active language, so the
pages that show one translate it as they are; its args stay English, and
so do the logs and the audit log. Host device problems and the Migrate
tab's reasons a disk is not copied are messages too.
The VM page's and the Settings page's views marked their messages with
gettext_noop, so every message they gave (a refused resize, a saved
setting, a QoS change, a busy VM) showed in English whatever the
language, though the catalogs translate them. They translate in the
request's language now; their module-level texts lazily. The Settings
page's group titles stay English in the view, as the page links them
by their slugs and translates them itself.
Two values went into translated messages as English codes: a job's
state ("... is running on this resource") and a QoS direction ("Remove
the inbound limit ..."). They are named as the pages name them.
A pool whose refresh failed, one busy with a volume copy for example,
was skipped without a word, so a hand-copied image stayed missing with
no reason given. The other pools are still refreshed; each failure is
shown with libvirt's error.
The API comment no longer says listing the ISO images refreshes pools.
The VM page refreshed every active storage pool to list the ISO images
for its CD-ROM drives. A pool holding large disk images took up to
seconds to refresh, most of the page's time, on every page load.
The page now lists the ISO images libvirt already knows. Images
uploaded through the panel are known at once. For an image copied to a
pool by hand, the Removable media section has a Refresh ISO list button
that refreshes the active pools and returns to the page.
A template's page was a VM's: it opened on Power, with only a note there
that a template is not started, while its clone form waited in a section
of Settings, next to a console, access, snapshots and stats that a VM
that never runs has no use for. A template's page now carries a Template
badge and a Clone button, opens on the clone form, and leaves out Power,
Access, Snapshot, Stats, the console settings, host devices and the
guest agent and address lines; Resize, Settings and Destroy stay for
whoever may change it. A page that no section opens shows its first.
A VM list showed what it read when it was loaded: a VM stopped from
inside its guest or with virsh, or made or removed elsewhere, showed only
after a reload, unlike the VM page, which reloads when its VM's state
changes. The lists of all VMs and of one host's VMs now poll the states
of their VMs, at once and then every 5 s as the VM page does, and reload
when an answer differs from the one before. The states come from one
libvirt call per host; a user who does not see hosts gets only their own
VMs. The page in use (a dialog, a field, an unsaved XML edit, a job
outcome shown) holds the reload until it is free; that check is shared
with the job panel.
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.
A running VM got its new CD-ROM on SCSI, the one bus the panel could plug
in then, and Windows does not see a virtio-scsi drive before the driver
on that ISO is installed. Add CD-ROM is now a dialog that chooses the bus
and the ISO: a running VM takes USB, first, which every guest sees and
which hot-plugs, or SCSI; a shut-off one SATA (IDE on pc), SCSI or USB.
libvirt has no empty USB drive, so a USB CD-ROM takes its ISO when it is
added and is detached instead of ejected, also while the VM runs.
A USB CD-ROM is a CD drive on QEMU's usb-bot only. Where QEMU has none
(RHEL 9), libvirt took usb-storage, which shows the guest a hard disk
that Windows does not read; the drive now asks for usb-bot, and such a
host refuses it with libvirt's message.
Windows 11 does not install without Secure Boot and a TPM 2.0, and the new
VM form offered neither: its firmware list was BIOS and one UEFI loader
guessed from file names, which on RHEL never matched the Secure Boot one.
The firmware choices are now BIOS, UEFI and UEFI Secure Boot, as the
host's libvirt reports them (its firmware features from libvirt 12.1,
before that its loaders), and libvirt picks the firmware itself: UEFI
without Secure Boot, or with Microsoft's keys enrolled. A TPM 2.0 switch,
shown when the host has swtpm, adds an emulated TPM. The create job
refuses a firmware or a TPM the host does not offer, and the API takes
both. The path-guessing helpers are gone.
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.
On a q35 machine each PCIe device (a virtio disk, a network card) takes
a root port of its own, libvirt makes only as many ports as the VM is
defined with, and a running VM gets no new one: adding a virtio disk to
such a VM failed with libvirt's "No more available PCI slots".
A new q35 VM is now defined with the PCIe root and 14 root ports, as
virt-install makes them: libvirt puts the VM's devices into them and
leaves the rest free for devices added while it runs.
When a running VM has no free slot, Add disk and Add network device say
what to do instead of libvirt's words: for a disk, the scsi bus when
the VM has a SCSI controller (its disks need no slot of their own), or
adding it with the VM shut down, where libvirt makes the port; for a
network device, shutting the VM down. A new volume whose attach was
refused stays in its pool, as before, to attach as an existing volume.
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.
gstfsd, the root service on each compute that rewrites a shut-off VM's
/etc/shadow and authorized_keys, did what any client on its port asked.
Now it needs GSTFSD_KEY (64 hexadecimal characters, in the unit's
/etc/default/webvirt-gstfsd) and does not start without it. Each
connection gets a new challenge; the panel signs its request for it
with HMAC-SHA256 and gstfsd checks the signature before any change, so
a request recorded on one connection is refused on another. gstfsd
signs its reply for the same challenge and the panel's nonce, and the
panel accepts only that reply.
Each compute has a gstfsd key, the host's GSTFSD_KEY: the compute forms
and the API take it and never show it, and an empty value on an edit
keeps it. The bootstrap script makes the key file once, readable by
root only; the README shows how to make it and where the panel takes
it. The traffic is still not encrypted: a remote panel's port stays
open to the panel's address only.
The Migrate tab offered every other host alike, and its plan showed
neither a file of the same name in a destination pool nor the disks of
the VM's next start, which the job then refused. Now:
- When the tab opens, the hosts are checked first: one that cannot be
reached, or the VM's own host under another record (the same libvirt
host UUID), is shown with why and cannot be chosen, and the disks of
the first one left are checked. The job refuses the VM's own host
under another name too.
- A pool of the destination that has a file of a disk's name is shown
but cannot be chosen for it; a disk no pool can take refuses the form.
- The next start's file disks the migration does not carry are listed;
one not on storage both hosts share refuses the form, as the job does.
Destroying a VM with its disk files forced it off first and then
worked out which files to delete, so a check that failed left the VM
stopped, and only this host's VMs and volumes were checked: a file on
shared storage that a VM on another host uses was deleted.
The files are now worked out before the VM is stopped: the disks it
runs with and those of its next start, as before with their snapshot
files and seed. A file a VM or volume of another of the panel's hosts
uses at the same path (shared storage is mounted at one path on every
host, as migration needs) is kept like one used here; another record
of the VM's own host is skipped, as there the VM itself uses them. A
host that cannot be read stops the destruction with its name, before
anything is stopped or deleted.
A user's quota counted each VM's running vCPUs, memory and disks, so a
larger value set for the VM's next start was not counted, and a clone
counted only once its VM was recorded, so a user could queue clones
past the quota. Now:
- Each VM counts the larger of its running and its next-start values.
- A clone job counts as one VM with the source's persistent vCPUs,
memory and disk size, which its plan stores, from its admission until
its VM is recorded; a failed, cancelled or resolved job no longer
counts. The clone's VM and its owner are recorded in one transaction,
so the quota counts either the job or the VM, never neither.
- The quota reads each VM's definition once (cached_reads).
With one owner per VM, the VM page and a user's page counted the VM's
owners and then added one in separate steps, so two owners added at the
same moment both found the VM without one, and it got two. The check
and the insert now run in one transaction that holds the ownership lock
(PostgreSQL's advisory lock; SQLite's IMMEDIATE transactions already
serialize them): the second waits for the first and is refused. The
audit row is written after the transaction, so a failure keeps its row.
The Stats tab stacked one large card per chart, so a VM with a few
devices made a long page, and its "Real Time" and "Logs" sub-tabs were
shown to every user although only a superuser may read the logs. The
owner chose the layout from rendered options: a state line, CPU and
memory side by side, one chart per NIC and disk below, each with its
latest reading next to its title, and a small Graphs/Logs switch for
superusers.
Codex reviewed the tab; this is fixed:
- Memory is shown in MiB (it was labelled MB), and its axis grows to
the RSS when the RSS passes the balloon size instead of clipping it.
- The CPU reading says it is of the host's CPUs.
- A NIC is titled by its MAC, not an invented "eth0", and its readings
are matched to its chart by the MAC: they were matched by position, so
removing a NIC while the page was open moved the next one's readings
into its chart.
- A VM that is not running says nothing is measured.
- The logs load whenever the Logs view is shown, by keyboard too; an
empty answer says "None" and a failed one says so, instead of an
empty table. The tab shows the latest 50 rows, with a link to all of
the VM's rows on the Logs page.
- The VM's header shows memory in MiB; it said MB.
The Destroy tab was a sub-tab with one sentence and a link; its
confirmation page said only "This action is irreversible!" over a
"Remove Instance's data" switch. The tab now shows the state and
"Review destruction". The owner chose the confirmation layout from
three rendered options: the VM and its host, that its definition,
saved state and snapshot records go and that a running VM is forced
off, two plans for the files (delete the disk files, or keep them), the
VM's disks, what is always kept, the NVRAM choice, and Cancel.
Codex reviewed destroying; this is fixed:
- A disk file that cannot be deleted keeps the files below it, which
it needs: they were deleted after it, leaving it broken. The files
are deleted overlays first (split_disk_paths_by_use orders them by
how many files each grows from), and if the files a kept one needs
cannot be read, none of the rest goes. A message names each file
kept so, and a failed deletion says the VM is removed.
The Snapshots tab had three sub-tabs: internal, external and the
lists, with the two kinds side by side as equals. The owner set the
direction: external snapshots are the way; internal ones pause the VM
while its memory is saved and can take long, so they stay only as a
fallback for a VM that cannot take an external one.
The tab now has the external snapshot form on top, its name and
description on one line, with its memory and freeze options; the
internal snapshot under a folded "fallback" line with its warning; and
one list of all snapshots, newest first, each on one line with its
name, description, kind and date, and Revert and Delete.
Codex reviewed snapshots end to end; these are fixed:
- The pause and memory lines follow the VM's state and the kind.
- An internal snapshot is reverted to on a shut-off VM only, on the
server too; the tab alone held that rule.
- A paused VM's revert says it comes back paused, not that it starts.
- An external snapshot waits, with the reason, while snapshots newer
than the one reverted to exist; the server refused it unexplained.
- Deleting an external snapshot says its files are merged with the
disks; "into the next one" was wrong for the last one.
- The description has no 45-character limit only the browser kept.
- Freezing is not shown ticked where it cannot be offered, and
unticking memory gives back the earlier freeze choice.
- Internal create, revert and delete refuse a saved state or a running
disk job, as external ones do.
The Access tab hid the console, the root password, the SSH key and the
remote viewer behind four sub-tabs. The owner chose a compact layout
from three rendered options: the state, a strip with the console and
the remote viewer, then two rows for root's password and key, each
saying why it waits when it does.
Codex reviewed access end to end; these are fixed:
- console.vv carries the console password only for users with the
passwordless console permission, as the console page passes it; it
gave it to every user who may open the console.
- The root password field is a labelled password input, not plain text
with a 24-character limit.
- Without a saved public key the key row is disabled and points to the
profile, instead of offering "None".
- A paused VM's console opens, as the console view allows.
- The remote viewer address and console.vv show only for a VNC or SPICE
console that listens beyond the host's loopback; a viewer on the
user's computer cannot reach the others, and a serial console gave a
pty://…:None address.
The Power tab hid each action behind a sub-tab of one sentence and one
button. The owner found the first rendered layouts crowded and chose a
compact one: the VM's state, then the actions its state allows in two
groups, those that keep the guest's data and the red ones that cut the
power, each group with one short caption.
Codex reviewed the power actions; these are fixed:
- Power Cycle and Force Off ask first, naming the VM and what is lost,
as the VM lists already did.
- The words say what happens: Power Off asks the guest to shut down;
Power Cycle cuts the power and starts the VM again, with its pending
settings; Force Off cuts the power.
- The tab follows states.allowed_actions, as the lists do; a running
VM's actions now include Force Off there too.
- A running template is not offered Power Cycle, which would start it
again; a shut-off template says to clone it instead of showing a
Power On button that only looked disabled.
- A paused VM tells its owner that an administrator can resume it; it
said an administrator had blocked it.
- Power On's please-wait dialog opens on the form's submit, from the
keyboard too.
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.
