Tells virt-install to not use UEFI, if it would normally default
to it.
This likely isn't too useful in practice, since all occasions we
default to UEFI require it. But it future proofs opt out in case
we ever start defaulting to UEFI in cases where BIOS still works.

Currently we will only apply the default `--cpu mode=host-passthrough`
config when _no_ `--cpu` config is passed. But this means if a user
configures ex. cpu `<topology>`, we don't set `host-passthrough` and
they get the libvirt/qemu default baseline CPU.
Instead, only skip the default config if the user manually
specified a `mode` or `model` value directly

Input XML can have non-existent disk images as long as `--preserve`
is used, or those disks are skipped for any reason. We already
handle that correctly in some cases, but others we fail. This
covers another one.

Our logic here is poorly duplicating libvirt's postparse logic.
Notably it will try to add bus=ps2 on non-x86, and misses obscure
cases like parallels.

The commit 6baa327d added active_pcr_banks support, but put it under the child
element <tpm>, which is wrong, It should be under sub child element <backend>.
Before:
--tpm model=tpm-tis,backend.type=emulator,backend.version=2.0,\
active_pcr_banks.sha1=on,\
active_pcr_banks.sha256=yes,\
active_pcr_banks.sha384=yes,\
active_pcr_banks.sha512=yes
It results in the following domain xml:
<tpm model='tpm-tis'>
<backend type='emulator' version='2.0'/>
<alias name='tpm0'/>
</tpm>
After:
--tpm model=tpm-tis,backend.type=emulator,backend.version=2.0,\
backend.active_pcr_banks.sha1=on,\
backend.active_pcr_banks.sha256=yes,\
backend.active_pcr_banks.sha384=yes,\
backend.active_pcr_banks.sha512=yes
It results in the following domain xml:

Currently `--panic default` for aarch64 doesn't even request
a `<panic/>` device due to quirky xmlbuilder behavior. Fix that,
but more generally just leave model empty and let libvirt fill it
in for us.

This wires up the guest.convert_to_vnc function to command line,

There's one suboption `qemu-vdagent=on|off`, defaulting to `off`

Wire up guest.convert_to_q35 to the CLI. We add one suboptions,
`num_pcie_root_ports=X`, matching the pre-existing
`--controller num_pcie_root_ports=X` option
Nothing fancy here. See man page docs for details

The old capabilities are extremely outdated. The new ones were

A few new features are advertised, and the details of the

The old capabilities are extremely outdated. The new ones were
captured on an Ampere Mt. Jade machine running Fedora 40.
Notable differences that are reflected in the output XML files
include the availability of SPICE, as well as EFI firmware and
ACPI support being advertised.
The test script had to be updated too, since both virtiofs and
memfd are now available.

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>

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.

Examples:
`virt-xml MYVM --add-device --sound FOO1 --sound FOO2` is not rejected
and will add 2 devices.
`virt-xml MYVM --remove-device --sound opt1=FOO1 --sound opt2=FOO2`
is not rejected, only the final `--sound` option is used.
`virt-xml MYVM --edit --sound FOO1 --sound address.type=BAR` is not
rejected. The commandlines will effectively be squashed
`--sound` can be any XML option, but trying to mix and match
options like `--sound` and `--disk` is always rejected.
These bits are unexpected and undocument, but have been around since
the beginning of virt-xml.
I can see us breaking compat on these in the future (particularly the
--remove-device bit), but that would need to be an explicit decision,
and announced appropriately. In the mean time, we should be testing
this so it doesn't accidentally regress.

Playing with this some more I found some deeper problems. For example
```console

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.
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.
