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.
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.
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.
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.
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.
