Libvirt enables blob resources for the virtio video device since 9.2.0.
It accelerates the display path due to less or no copying of pixel data.
E.g.
virt-install \
... \
--video model.type=virtio,blob=on
It results in the following domain xml:
<video>
<model type="virtio" blob="on"/>
</video>

Set kvm pv-ipi feature by --features argument.
E.g. virt-install --features kvm.pv-ipi.state=off
It results in the following domain xml:
<features>
<kvm>
<pv-ipi state='off'/>
</kvm>
</features>

We will not enable hyperv_reset feature as modern Hyper-V versions don't
export it.
We also don't enable hyperv_reenlightenment as it is mostly relevant
when migrating VMs that are running Hyper-V inside and requires other
bits to work correctly.

We will no longer enable hyperv features based on libvirt and QEMU
versions.
Some tests don't use the kvm-x86_64-domcaps-latest so the code will now
not enable Hyper-V features. There are still other test cases that cover
Hyper-V features so instead of mangling with URI for these tests update
test data.

Playing with this some more I found some deeper problems. For example
```console
[:~/src/virt-manager] (main) $ ./virt-xml test-for-virtxml --connect test://`pwd`/tests/data/testdriver/testsuite.xml --print-diff --edit 1 --video model=FOO --edit 2 --sound model=BAR

There's other weirdness too, though it's mostly strange plays on previous weird behavior
* `--edit --video model=vga --edit --sound model=ich9 --video model=qxl` works
* `--add-device --sound model=foo --video model=bar` was previously rejected but now works
* `--remove-device --video model=vmvga --sound model=sb16` was previously rejected by now works
Fixing all this is not trivial. So I think we need to revert and go back to the drawing board.
This makes it easier for users to change video model from QXL to
different model as QXL is special and uses other attributes that are not
supported by any other model. Without this code libvirt would report
error or user would have to request `clearxml`.

When Spice graphics is used QEMU creates a Spice server and communicates
with Spice client using multiple channels. These channels are used by
the spice devices as well. Without the Spice graphics defined there is
no use for the other devices. In addition libvirt will report error for
such configuration.

Fix the cloud-init config file for --clouduser-ssh key.
Also change ssh_authorized_keys to `ssh_authorized_keys`, and make sure
default user is not deleted when setting ssh key for root.
Fixes commit 22478f307d (virt-install: Add --cloud-init clouduser-ssh-key=)

conn.fetch_all_vols() is slow, taking ~0.03s every time it's used. When
handling with a large number of paths, its performance is too bad and
could stuck UI for a very long time.
DeviceDisk.paths_in_use_by is added to help handle many paths with
only one call to conn.fetch_all_vols().
Add adaptations for loongarch with the following features:
Default video Support

Usb tablet and usb keyboard
rng and memballoon
sound device
Usb controller

While the shorthand saves a tiny bit of typing, it is confusing
to people coming from QEMU, where -cpu host is the equivalent
of our --cpu host-passthrough. It's better to stick with the
unambiguous names used by libvirt.
Besides, the GUI already uses "host-model" throughout, so
advocating its use in the CLI too increases the internal
consistency.

This won't make any difference on x86, where either SATA or IDE
is used depending on the machine type, but on other architectures
we want virtio-scsi for a reasonable chance that the guest OS
will recognize the disk.

Most existing disk images expect UEFI; those that don't, require
either using direct kernel boot or manually providing a firmware
image, both of which imply user intervention.
Using UEFI by default means that at least images belonging to
the first group, of which more are going to pop up as the
ecosystem matures further, can work out of the box.
