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.
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.
- 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.
Cloud images read their first-boot settings with cloud-init. The panel
served them only over HTTP, which a VM reaches only with the network
and a reverse DNS name for its address. A new VM can now carry them
itself: Cloud-init seed (Advanced) on the create form, or cloud_init in
the API.
The job writes a NoCloud seed, an ISO labelled cidata, into the disk's
directory pool as cidata-<uuid>.iso and puts it in the VM's CD-ROM
drive. Its meta-data holds the VM's UUID as instance-id and its name as
hostname, written as JSON so a VM named 123 or yes keeps a string
hostname; its user-data is what the HTTP datasource serves, with the
creating user's SSH keys. The ISO is built with pycdlib and written
through a libvirt stream, as the NVRAM copy is, now one helper for both.
A seed needs a CD-ROM bus and a directory pool, else the create is
refused. A failed create deletes the seed with the new disk, recovery
names one left behind, and deleting the VM with its disks deletes its
seed, found in the pools by name even when ejected. A clone's drive is
left empty: the seed is the source VM's identity.
