The only backups of the panel were the ones taken by hand before an
update. Now `manage.py backup` writes a new directory under backups/
with a consistent copy of the sqlite database (the backup API, while
the panel runs, checked with PRAGMA integrity_check), the secret key,
the worker's node_id, settings.py, the SSH keys of the panel's user
and, outside Docker, the commit. It keeps the newest 7 (--keep N) and
deletes older ones only after a good backup; a failed one leaves
nothing, and a second run while one runs fails. Files are mode 600,
directories 700: the database holds compute passwords and keys. With
PostgreSQL the database is left out.
It runs daily at 03:15: in Docker from the image's cron into a new
volume, webvirtcloud-backups; otherwise from webvirt-backup.timer,
which the installer and the manual steps install. A backup has the
layout of the update backups, so the restore steps take either.
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.
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.
The Settings page was one tall column of cards, a label column beside
every field and True/False chosen from a select. Now an index of the
groups stays beside the cards on a wide screen and wraps above them on
a phone; each group lays its fields out in two columns with the label
above; a True/False setting is a switch; each Save names its group.
A switch posts nothing when off, so a hidden False of the same name
comes first and a checked switch's True, posted last, wins: the view
and its was-KEY check stay as they are.
The top of a VM's page was one line of values between pipes, an icon for
the guest agent and a hidden snapshot count, then a row of big action
icons; the host links sat in a bar fixed to the bottom of the window,
over the content.
One card now holds it all (design chosen by the owner from four):
- the name with the state badge, the title under it, and where the VM
is: its host and the host's VM list for administrators, the VM list
for owners;
- OS details (with a connected guest agent) and Refresh;
- the guest agent's state in words and the snapshot count;
- CPU, memory, each disk with its device name and size, and the IPv4
addresses, labelled;
- the page's sections as small labelled pills in the card's footer: one
row from 992 px, wrapping below.
The page has no other heading: base.html's heading area is a block it
leaves out.
Each section below it (Power, Access, Resize, Snapshot, Settings, Stats,
Destroy) is a card of the same kind, so the page reads as one design
(owner's choice of two): its sub-tabs as a small underlined nav in the
card's header, its panes in the card's body without their own borders.
Buttons are of normal size in the theme's primary colour, and those that
cannot be undone (Power Cycle, Force Off, Destroy) in the danger colour.
The Stats charts lose their coloured borders. instance_tabs.js finds the
Settings tabs by their tablist role.
The bottom bar and its setting (VIEW_INSTANCE_DETAIL_BOTTOM_BAR) are
removed, and with it the CSS that kept the old Settings tabs on one line.
- A named CPU model is written without check='none' and with
fallback='forbid': libvirt checks before the start that the host runs
it, and it is not swapped for another model.
- Mode maximum is written as that mode; it was written as a model named
maximum.
- Model names up to 64 characters: the -noTSX and -IBRS models, the ones a
mixed set of hosts needs, were refused at 20.
- The mode or model is checked against the host's capabilities when the VM
is defined, from the page and the API alike; no CPU element (QEMU's
oldest default CPU) is no longer offered.
- The default CPU mode setting offers the modes the new VM dialog has;
no-model and custom, which matched none of them, become host-model.
- A group sent all its fields, and the ones left as they were undid
what another administrator had saved meanwhile. Each field now sends
the value the page showed, and only a field edited since is saved.
- A database error partway left the group half saved. The group is now
saved in one transaction, written as one audit row: "Settings: change
Console Scale to True, Console Clip Viewport to True".
The descriptions were tooltips, many only repeating the setting's name
("Cpu modes", "Debug for user quotas"). Now shown under each field, they
say what the setting changes: what a new VM or disk gets, how the
console starts, what a page shows. A migration writes them.
The page listed 37 settings by name, each its own form saved as soon as
its list or field changed, with the description only in a tooltip. It
now shows them in groups (New VM defaults, Disks, Clones, Console, VM
access and owners, Snapshots and jobs, Login, Lists and pages) with each
description under its field and the label tied to it. A group's Save
button saves its changed settings, or none when one is refused, and
says which were saved; number settings are number fields with their
range. Language and theme are under Appearance with their own buttons.
A setting in no group shows under Other.
The Settings page saved whatever was posted, and some lists offered
values the panel cannot use:
- Quota Debug could not be turned off: "False" is a non-empty text and
counted as on.
- VM Clone Name Prefix showed as a True/False list, so no prefix could
be typed, and touching it set the prefix to True.
- Disk SCSI Controller listed " lsilogic" with a space, never shown as
chosen, and virtio-blk, which is no SCSI controller.
- VM Machine Type listed x86_64, an architecture; VM CD-ROM Device
listed virtio, a bus a CD-ROM cannot use.
- Logs per Page and Disk Owner UID/GID are read with int(): a letter
broke the logs page and VM create.
A migration fixes the lists and moves a value they no longer offer to
the default (the clone prefix keeps its text). A listed setting now
takes one of its choices, and every number setting a whole number in
its range, checked before it is saved.
The Logs page now records the panel's own records too: users (add,
change with the changed fields, delete, block, unblock, an admin's
password set, a user's own password change including the first-login
one, own profile edits), groups with their members and permissions,
VM owners from the accounts pages and from the VM page, OTP QR code
mails, flavors from web and API, app settings and the theme,
removed-VM records and SSH keys. No row carries a password or a key.
- A user is created in one transaction: when a VM named in
NEW_USER_DEFAULT_INSTANCES is missing, no half-made user stays.
- The OTP mail checks the email address before it creates a device;
without one it writes a failed row and makes no device.
- The VM page's owner rows read "VM web-1 owner bob: add" and
"...: remove" instead of "Add owner: bob" and "Delete owner: 17"; a
second owner refused by the single-owner setting is a failed row.
Owner rows keep the VM's host and name, so the VM's log tab shows
them.
- A setting or theme posted with its current value is no change and
writes no row; the old free-text setting rows are gone.
Host-side objects (networks, storage, interfaces, secrets, filters)
follow in the next layer.
An accessibility scan (axe-core, WCAG 2 A/AA) of every page found 87
elements without a name. Icon-only buttons and links (the navbar's
administration menu on every page, the add/create buttons, the flavor
delete and back buttons) get a title, which is also their tooltip; the
labels of the language, architecture, chipset and filter selects point
at them; the memory bar is named. The shared delete confirmation page
had an empty <title> and heading, as no view passes "title": it says
"Delete <object>". The power-off form's aria-label was misspelled.
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.
A disk-only snapshot was taken without any space check, though its
overlays grow as the guest writes and a later delete merges them down;
a full pool pauses the guest and can leave the snapshot undeletable.
Only a memory snapshot was checked, for the memory alone.
Before a snapshot, each storage pool with a disk of the VM must have
free a share of those disks' virtual size (10%, at least 1 GiB), and
the pool of the memory file the VM's memory on top. Both values are on
the Settings page (Snapshot Free Percent, Snapshot Free Min GiB; 0
turns a rule off, an invalid value keeps the default). The pools are
refreshed first, and a failed refresh or an unreadable volume refuses
the snapshot instead of skipping the check; a disk in no pool is not
checked. Nothing is reserved: later writes can still fill a pool.
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.
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.
nginx serves STATIC_ROOT (staticfiles/) since collectstatic moved there,
but the theme view wrote only static/css/wvc-main.min.css, so a new theme
showed up only after the next collectstatic. The view now also writes the
collected copy when collectstatic has run; the source copy stays so a
later collectstatic keeps the theme.
A volume of an LVM or iSCSI pool can be attached: by its own path, with
the format its volume reports (raw when the pool knows none). Detaching
a disk takes each definition's own description of it, so a disk only in
the persistent definition goes too. Every NIC type can be a boot device;
bridge and direct NICs were dropped from the boot order. The video model
is a value, never parsed as XML. QoS changes clear the page's read cache.
The NIC model "default" leaves the choice to libvirt instead of writing
model "default", and rt18139 is rtl8139: a VM with either did not start
(checked on a RHEL 10 host). A migration corrects the default NIC type
setting.
The first appsettings migrations insert the default rows with fixed ids,
which a PostgreSQL id sequence does not see; the login lockout migration,
the first to insert without an id, then collided with id 1. It now moves
the sequence past the existing rows first (a no-op on sqlite), which also
covers a database upgraded from any earlier migration. A test compute
password exceeded its 14-character column, which only PostgreSQL enforces.
Reviewing the error handlers outside instances/ turned up three that masked or
swallowed the failure they caught:
- appsettings/settings.get_settings() runs on every request (middleware) and
loads app_settings from the database. Its bare `except: pass` left `entries`
unbound on a database error, so the next line raised UnboundLocalError
instead; it also caught KeyboardInterrupt/SystemExit. It now catches
DatabaseError and returns, keeping the already-loaded values.
- vrtManager.network.refresh_dhcp_leases raised a formatted string
(`raise f"..."`), which Python rejects with TypeError, hiding the real
DHCPLeases failure. It now raises util.OperationError, which the API/HTML
error handling already renders as a libvirt error, and clears self.leases.
- storages.views.get_volumes caught libvirtError and answered 200 with an empty
body, so the caller could not tell a failed pool read from an empty pool. It
now returns 400 with the error.
The other broad handlers reviewed (appsettings/nwfilters/virtsecrets views,
storages/upload cleanup and recovery paths, vrtManager display getters) report
the error or are best-effort and were left as they are.
Tests: get_settings() survives a database error during the query and during
iteration without raising and still loads a real value; refresh_dhcp_leases
raises OperationError (keeping the cause) not TypeError; get_volumes returns 400
on a listing failure and the sorted volumes on success. The tests fail on the
previous code.
With "VM Clone Auto Migrate" on, a new clone was migrated to a random
compute, whatever storage, CPU or network that host had, and a failed
migration showed as a failed clone although the clone existed.
The setting and its code are removed; migration appsettings.0015
deletes the setting. A clone can be migrated afterwards like any VM.
The README's update notes list the migration changes: the migration
address, storage pools for the disk check, and this setting.
Nothing limited failed logins: a password could be guessed at the speed
the server answers. django-axes (8.3.1, Django 5.2, Python 3.10-3.13)
now counts them.
- A user is locked for the address the failed logins come from
(username and IP together), so an attacker cannot lock someone out
from elsewhere and users behind one NAT address do not share a lock.
A successful login resets the count. axes sits in front of every
authentication: the login page with or without OTP, LDAP and the API.
- The number of failed logins (default 5) and the lock time in minutes
(default 15) are on the Settings page (LOGIN_FAILURE_LIMIT,
LOGIN_LOCKOUT_MINUTES, added by migration appsettings.0014) and apply
at once; an invalid value falls back to the default. Unlock with
"manage.py axes_reset_username <username>".
- Behind the bundled nginx every request comes from 127.0.0.1; the
client address is read from X-Real-IP, which nginx sets, but only for
requests from a loopback address or from LOGIN_TRUSTED_PROXIES, so a
forged header does not escape a lock.
settings.py.template gets the app, middleware, backend and AXES_*
settings; README tells existing installations what to copy. Tests that
call client.login now pass a request, which the axes backend needs.
The new tests fail with axes disabled.
The settings page lists the themes of SASS_DIR and writes wvc-main.scss
into it when the theme changes; the value could be any path, so a
superuser could make the app list and write files anywhere it may
(CodeQL py/path-injection).
SASS_DIR is now accepted only if it resolves to an existing directory
inside the project (the default is dev/scss). A stored value outside it
is not used: the page shows an error and offers no themes, so nothing
is written. Installations that keep their SCSS outside the project
need to move it under it.
The tests fail on the previous code for an absolute path, "../",
a path climbing out and a missing directory, and for a stored value
outside the project.
The settings page took the posted theme name as it came and wrote it
into the @import lines of wvc-main.scss and the compiled CSS: a name
with "../" or a quote imported files outside the themes directory
(CodeQL py/path-injection; the page is for superusers).
The name must now be one of the directories in SASS_DIR/wvc-themes, the
list the page already offers; anything else is refused with a message
and nothing is written. themes_list is empty when SASS_DIR has no
themes, so every name is refused then.
Checked with the real dev/scss: flatly is applied and compiled as
before, "../../etc" is refused and leaves the CSS alone. The test fails
on the previous code.
SPICE was removed earlier; its leftovers and the console type choice go
too:
- the console settings form, update_console and the backend no longer
offer or change the type; an invalid console form now shows its
errors instead of being ignored;
- the create form, the API serializer and create_instance no longer take
a graphics type, new VMs get VNC; get_graphics_types and the graphics
entries of the domain capabilities are gone;
- migration appsettings.0013 deletes QEMU_CONSOLE_DEFAULT_TYPE;
- a VM defined elsewhere with another graphics type gets "Console type
... is not supported".
The locale catalogs still reference the deleted SPICE templates in
source comments; regenerating them is left to the translation work.
Super-linter ran from the unpinned :latest image and, because of
branches-ignore: [master], never on pull requests to master. Ruff now
checks syntax errors and pyflakes rules (E9, F) on every push and PR.
Fixes the existing findings: unused imports and variables, an unused
duplicate import in instances/tests.py, and the star import in
accounts/views.py. settings-dev.py keeps its star import of the base
settings.
The *migrations/* ignore rule is removed. appsettings, computes and
logs pin default_auto_field to AutoField, so makemigrations --check
reports no pending BigAutoField migrations and existing installs need
no schema change.
The Vagrant provisioning no longer runs makemigrations, which created
install-specific migration files that conflict with the committed
history; it only runs migrate.
- Computes API: mark password as write_only in ComputeSerializer, restrict ComputeViewSet and architectures to IsAdminUser.
- Instances API: enforce user ownership tenant isolation in InstanceViewSet.list, restrict MigrateViewSet and CreateInstanceViewSet to IsAdminUser, require IsAdminUser for mutating FlavorViewSet.
- Storage, Network, and Interface APIs: restrict StorageViewSet, VolumeViewSet, NetworkViewSet, InterfaceViewSet to IsAdminUser.
- AppSettings & NWFilters: protect appsettings and nwfilter views with @superuser_only (403 Forbidden for non-superusers).
- noVNC Console: sign tokens with TimestampSigner (salt='console.novnc', max_age=600), verify signature and user authorization in novncd with backward-compatible fallback for debug/test mode.
- Accounts: avoid hardcoded default admin password; generate cryptographically secure random password unless ADMIN_PASSWORD is set (preserve 'admin' in test runner).
- gstfsd daemon: bind to 127.0.0.1 by default instead of 0.0.0.0.
- Tests: added comprehensive test coverage for API security, token expiration/rejection, and view permissions (132 tests passing).
- Remove obsolete spice-html5 static assets and SPICE console templates
- Restrict default console types to VNC with migration 0012
