In real world silicon though it is rare to have high socket/die counts,
but common to have huge core counts.
Some OS will even refuse to use sockets over a certain count.
Thus we prefer to expose cores to the guest rather than sockets as the
default for missing fields.
This matches a recent change made in QEMU for new machine types

Although using --cpu topology.XXX is the preferred way to set topology,
it is still possible via the --vcpus parameter. For consistency, this
should support the full set of parameters, so dies needs to be added.

This includes support for the following suboptions:
* name (<shmem name=X>)
* role (<shmem role=X>)
* model.type (<shmem><model type=X/>)
* size (<shmem><size>X)
* size.unit (<shmem><size unit=X/>)
* server.path (<shmem><server path=X/>)
* msi.vectors (<shmem><msi vectors=X/>)
* msi.ioeventfd (<shmem><msi ioeventfd=X/>)
xorisso is the still maintained isoinfo alternative, and may be
the only iso reading tool in RHEL9, so we need to support it.
Make it the default for our spec file and test suite too

If specified, this errors if no OS name was detected or manually set.
So --os-variant detect=on,require=on will error if no OS is detected.
name= can be used as a fallback, so test and document this case

This adds the following --os-variant suboptions
* name=, short-id=
* id=
* detect=on|off
Functionally this does not change behavior, just adds explicit
sub options for behavior we already support

The --os-variant option naming is pretty crappy and mostly a historical
artifact. Ideally this would be named just `--os` but I'm afraid that
would cause confusion with libvirt's <os> XML
Add --osinfo as an alternate commandline naming. If we ever want to
transition documented use of --os-variant it will help to have the
alternative around for a few releases

The --xml option allows users to request raw XML edits to virt-install
or virt-xml generated XML. This gives users a bit of a workaround
incase we don't have proper support for some XML property. The --xml
option can gain more features in the future if it makes sense, like
setting XML namespaces for example.
Basic usage is like: virt-install --xml ./@foo=bar ...
Which will change the generated <domain> XML to have
<domain foo='bar' ...
virt-xml works similarly. It can only be combined with --edit currently.
This only works with xpaths rooted against the entire document.

Add a --iommu option to configure IOMMU parameters as described in
https://libvirt.org/formatdomain.html#elementsIommu
E.g. 'virt-install --iommu model=intel,driver.aw_bits=48,driver.iotlb=on ...'
will generate the following domain XML:
<devices>
<iommu model="intel">
<driver aw_bits="48" iotlb="on"/>
</iommu>
</devices>

Generally this doesn't work with qemu metadata locking nowadays,
and it was never a safe idea to begin with, because disk contents
could be in an inconsistent state.

This was raised here:
https://www.redhat.com/archives/virt-tools-list/2019-June/msg00117.html
Quoting from that:
"""
virt-convert takes an ovf/ova or vmx file and spits
out libvirt XML. It started as a code drop a long time ago that could
translate back and forth between vmx, ovf, and virt-image, a long dead
appliance format. In 2014 I converted it to do vmx -> libvirt and ovf ->
libvirt which was a CLI breaking change, but I never heard a peep of a
complaint. It doesn't seem to do a particularly thorough job at its
intended goal, I've seen 2-3 bug reports in the past 5 years and
generally it doesn't seem to have any users. Let's kill it. If anyone
has the desire to keep it alive it could live as a separate project
that's a wrapper around virt-install but there's no compelling reason to
keep it in virt-manager.git IMO
"""
Nothing has changed since then, so here is the removal.

When running virt-install as root, user-login would be automatically set
to "root", causing an installation failure in the most part of the
distros (if not all of them).
In order to avoid such failures, let's raise a runtime error in case the
user-login used is "root".

Let's allow setting the login of the guest user.
Using the user from the system is a quite good fallback, but would break
unattended installations when running virt-install as root. Thus, for
those cases, it makes sense to have the option of setting the user
login.

Let's not expose the user/root password in the CLI and, instead, let's
rely on a file passed by the admin and read the password from there.
