Networks, Interfaces, Storages, Storage, Volume, MigrateInstance and
CreateInstance were unmanaged models with no table, there only so that
ModelSerializers and the new VM ModelForm could take their fields. They
made content types and migrations, and their DO_NOTHING foreign keys
added reverse accessors that meant nothing (Compute.host,
Compute.target_host, Instance.source_host).
The serializers are plain Serializers and NewVMForm a Form, field for
field as the models gave them (types, lengths, required, defaults, the
minimum of 1 for vCPUs, memory and disk size; the form's labels are
still derived from the field names). Compared field by field before and
after, the API schema changes only where the models were wrong:
- no int64 bounds on the listing fields;
- the interface fields lose the titles that named the wrong column
(type was "Status", state "Device", mac "Forward");
- a pool's volumes is a list of objects (it was described as an
integer) and a volume's allocation an integer (it was untyped).
One migration per app deletes the models; none touches a table.
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.
migrate_instance sets autostart on the destination (it is per host and
the migration does not carry it) and deletes the NVRAM file libvirt
keeps on the source. A worker that stopped after libvirt moved the VM
skipped both: recovery only recorded the move, so an autostart VM no
longer started after the destination rebooted, and a later VM of the
same name on the source started with these UEFI variables. The job now
records both before the move, and recovery does them after a proven
move; a step that fails is a warning of the job's result.
After a successful copy, recovery defined the clone; a define that
failed raised, and recovery retried it with the same result. One case
is certain: a worker killed after define_clone copied the UEFI
variables but before it defined the VM leaves <clone>_VARS.fd, and every
retry is refused because the volume exists. The job then waited for
recovery with its claims on the source VM and the clone's name. A
libvirt error now ends it uncertain, naming the error and the copied
volumes; an unreachable host still waits.
Recovery retried a reconcile that raised every 10 minutes with no end. A
job whose compute was gone for good stayed running ("Waiting for
recovery") and kept its claims: it could not be resolved (only uncertain
jobs can), cancelled, or have its compute deleted. After an hour of
failed reconciles the job ends uncertain with the last error; it keeps
its claims, and an administrator checks the VM and resolves it. A
reconcile that answers restarts the hour.
A double click made two tokens: the second key was shown, the first
never, yet it stayed valid until it expired and took a place of the ten.
A user's token names are now unique, checked under a lock on the user's
row, which also keeps two forms sent at once from passing the limit
together. tr and zh too.
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.
The Lost OTP? page, open without a login, and the admin's Email OTP QR
code mailed the QR code itself: the TOTP secret then stayed in the
mailbox and on every server the mail passed. The mail now carries a
signed link, good for an hour, to a page that shows the QR code (not
cached); the page shows nothing for an old or altered link or a user
without a device. tr and zh too.
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).
The worker's checks refuse with PermissionDenied or Http404, which carry
no text: the job failed with an empty error and its Logs row gave no
reason. They now read "You may no longer do this." and "The virtual
machine is no longer in the panel." (tr and zh too).
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.
EMAIL_TIMEOUT was not set, and Django's SMTP connection then waits for
a server without end: one that accepts the connection and stops
answering held the request's thread for good, also on the login page's
Email OTP form, which anyone may post. The settings template sets 10
seconds. An administrator whose mail fails is told why on the account
page instead of getting an error page.
Nothing removed the Logs page's rows, which every action and every
failed login adds, or the database sessions past their expiry. The job
worker's housekeeping now deletes the rows older than Log Retention
Days, a new setting under Lists and pages (1-3650, 365 by default), and
the expired sessions.
The page where a user changes their own password and the one where an
administrator sets a user's password shared an old card: a horizontal
form, a blue Cancel and a green Change. The administrator's had Django's
"Password-based authentication: Enabled/Disabled" with a paragraph about
other backends, and its password fields stayed while Disabled was chosen.
Both pages now have the user and group forms' layout, each its own
template. The administrator chooses how the user signs in, With a
password or Without a password (such as LDAP), and the password fields
and "must change it" show only with a password; Cancel goes back to the
user. A user's own page says that their other sessions end, or, when
they must change it, that they choose one before going on, without a
Cancel. A refused password is said at its field only, without the
general "Wrong Data Provided". The section styles of these forms move
into webvirtcloud.css.
The group form put every user as a checkbox in one unsorted list, the
members among them, with no way to find one: past a few dozen users a
wall of names. Its name field ran the width of the page.
It now has the user form's sections (Group, Permissions, Members), each
with what it is for beside its fields. Members come first, then everyone
else, each by username with their full name; a search box filters them
by username, name or e-mail (table_filter.js). A form's search, marked
data-forget, starts empty: the list pages remember theirs per page title,
which here is the same for every group. Hidden users stay in the form,
so saving while filtered keeps them. The button says Create group or
Save changes.
The create and edit pages of a user had one form for both, ordered for
editing: permissions first, the name and password folded below them and
the quota folded and closed at the end; a new user's name came last.
Both pages now go Account (name, password, may sign in), Role, Quota,
then Groups and permissions, each section with what it is for beside its
fields. Template editor and Superuser become one Role choice with User:
choosing Superuser hides the quota and permissions, which a superuser
does not need (no quota check applies, every permission is theirs); it
keeps the is_staff it had. The quota is always open: each limit takes a
number from 0, or No limit, which is kept as -1 as before; memory is
entered in GiB and kept in MiB, shown exactly so saving a user again
changes nothing. The button says Create user or Save changes.
The New password field sits under the "Set a new one" choice and shows
only while it is chosen, so its help no longer has to say so. The Console
heading above the Console type label goes, and the save button has the
size of the other tabs' main buttons.
The VM's XML editor takes most of the window's height and is framed like
a form field. The review dialog shows removed and added lines on a red and
green tint, and each part of the diff starts with its line number instead
of the unified diff's @@ header.
Random and Guess join the MAC field as one input group, the Clone tab's
secondary buttons are outlined like the other tabs', and the NIC and disk
lines read as plain text ("default pool, qcow2") instead of dot-joined
fragments.
A NIC's row put its name and host device in one column, "Source",
"IPv4 unknown" and the link switch in another, and its model, MAC and
filter behind Device details; every NIC also had a "QoS limits · none"
fold and solid Edit, Add QoS and Delete buttons.
Now a row reads eth0, a cable, then the source: the cable is solid green
while the link is up and dashed grey while it is down. Under it are the
IPv4 addresses (or "No IPv4 address known") beside the link switch, and
a line of model, MAC, filter and whether bandwidth is limited. Device
details keep the type, the host device and IPv6; QoS limits show only
for a NIC that has one. The buttons are outlined. Dialogs, form names
and posts are unchanged.
The tab opened on "Snapshots · Active" above the form, and listed the
snapshots below it as rows of "name · description · external, current
· date" with a solid red Delete on each. Which snapshot the VM goes on
from was the word "current" among the others.
Now a line runs down the tab, newest first. On top is Now, the VM in
its state's color, with the form that takes a snapshot there. Below it
each snapshot is a point: its name and date, its description on a line
of its own, its kind under them. The one the VM goes on from is filled
and says so; the others are rings. Revert and Delete are small outlined
buttons. Forms, confirmations and the rules that disable them are
unchanged.
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.
The tab put the console, a remote viewer address and two root forms at
one weight under "Access · Active · VNC", named buttons after their
implementation (VDI, Get console.vv), and repeated why the root forms
were disabled under each of them.
Now it has two sections. Screen: Open console with what it does, and
the remote viewer on a row of its own (address, Open, Download .vv
file). Log in as root: one line says how a password or key reaches the
guest now, written to the disk of a shut-off VM or sent through a
running VM's guest agent, or what to do when neither works; the
password and key rows follow with aligned labels. Ids, field names and
posts are unchanged.
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.
A job stored its error and its result's warning as English text, much
of it built with the values in it (volume paths, a disk, libvirt's
error), so no catalog could translate it, and the job pages and panel
showed English whatever the language.
A job now stores them as messages: our English text, marked for
translation, and its values; libvirt's own text is a message without
values and is shown as it is. The jobs API and pages put them in the
reader's language. OperationError keeps its text and values apart for
the same reason, so a refusal raised while a job is submitted is shown
translated too. Messages one after another still read as sentences.
Errors stored before are kept as one message each, shown as they were.
The job panel on VM and storage pages wrote its buttons and notes in
English (Cancel, Open, Refresh, Dismiss, Finishing..., Files not
removed, Worker unavailable, Cancel failed) and its state badge as the
state's code, and the jobs API gave the phase untranslated. The panel
now takes its texts and the state labels from the page's settings, and
the API gives the phase in the viewer's language, as it gives the
label; the job pages show that phase.
A job that cannot be cancelled and ran past its time limit had
"(over its time limit)" written into its phase, which then matched no
translation. The phase stays as the job sets it, and the pages say the
job is past its limit.
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.
The Chinese catalog had not been extracted since 2023: of the panel's
1749 messages, 878 were missing and 455 carried old fuzzy guesses, and
some of those marked done said something else ("Delete API token" read
"Delete SSH key").
Every message is translated again, with one glossary for the panel's
terms, placeholders and markup checked against the English, and the
panel offers Simplified Chinese again. The CI check covers it too.
One message of the VM page (the console password's help) never reached
any catalog: its escaped quotes cut it short at extraction. It is
written with single quotes now, and translated in both catalogs.
The language choice on the Settings page listed every language Django
knows, 99 of them. Six catalogs (Czech under the wrong code, German,
Spanish, French, Russian, Ukrainian) translated none of the panel's
messages, so choosing one of them, like most of the others, showed
English. The Turkish catalog lacked the four newest messages.
The panel now offers English and Turkish (LANGUAGES). The empty
catalogs and the English one, which has nothing to translate, are
removed. Turkish translates every message again. CI checks that the
offered catalogs translate every message and that their compiled
files are up to date; the README says how to update them.
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.
Without a migration address libvirt sends a migrating VM to the
destination's own host name, which the source host often cannot resolve:
a live migration to a host added without one failed ("Unable to resolve
address ..."), also when the other host had one. The destination's
address on the Computes page, which the panel reaches it at, is now the
default; the migration address stays for another network. A host the
panel reaches on its loopback keeps libvirt's default.
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.
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.
The Turkish catalog had not been extracted since 2024: of the panel's
1727 messages, 817 were missing and 489 carried old fuzzy guesses, so
most pages, dialogs and messages showed in English, and some fuzzy
guesses said something else.
The catalog is extracted again (obsolete entries dropped) and every
message is translated, the earlier terms kept (Sanal Makine, Sunucu,
Depolama havuzu, Birim, Anlık görüntü), placeholders and markup checked
against the English. The Settings page's names and descriptions come
from the database through migrations that did not mark them for
translation; they are marked now (gettext_noop, the stored values
unchanged), so they are in the catalog too.
