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

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

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.

It is common on x86 and other architectures to install a guest from
network by using "--boot hd,network" with virt-install - as long as
the hard disk is not bootable yet, the installation will be started
via network, and once it finished, the guest can boot from hd during
the next reboot.
However, this does not work on s390x since this architecture only
supports one single boot device to be passed to the guest. Thus add
a note to the documentation to avoid that people are running again
into this common pitfall.

Provide ready to use recipes for explicitly enabling and

the more extensive information found on the libvirt website.
Setting loader_secure=yes is only one part of a proper Secure
Boot setup, so stop documenting it in the section about manual
firmware selection to avoid confusion.

This allows support for host/guest clipboard sharing when using vnc
guests (and possibly other graphics types in the future). This channel
is similar to the spicevmc channel, but it contains a couple additional
options to enable/disable clipboard sharing and specify the mouse mode.
In the case of spice, these settings are specified on the 'graphics'
element, but for qemu-vdagent, they are specified on the channel. For
example:
--channel=qemu-vdagent,source.clipboard.copypaste=on,source.mouse.mode=client

This is a virt-xml option to refresh a VM to use the latest machine

It's generally not as valuable for non-x86 where we don't have the
history of supporting non-virtio OSes, but as time goes on it will
likely become more relevant for non-x86 arches, so let's make this
change now to get ahead of it.

The code previously was just encoding the same defaults as libvirt,
which doesn't really add anything.
Instead, let's prefer type='emulator' model='tpm-crb', which
gives the most modern virtualization friendly config. When we don't
know if that will work, we mostly leave things up to libvirt to fill
in.

For the x86 + hvm case, failure to specify an --osinfo/--os-variant
OS, and failure to detect an OS from install media, will now throw
a big error:
```
--os-variant/--osinfo OS name is required, but no value was
set or detected.
This is now a fatal error. Specifying an OS name is required
for modern, performant, and secure virtual machine defaults.
If you expected virt-install to detect an OS name from the
install media, you can set a fallback OS name with:
--osinfo detect=on,name=OSNAME
You can see a full list of possible OS name values with:
virt-install --osinfo list
If your Linux distro is not listed, try one of generic values
such as: linux2020, linux2018, linux2016
If you just need to get the old behavior back, you can use:
--osinfo detect=on,require=off
Or export VIRTINSTALL_OSINFO_DISABLE_REQUIRE=1
```
The thread goes into more detail, but basically, for x86 VMs at least,
it's unlikely you will _ever_ want the default 'generic' behavior,
which gives gives no virtio, no PCIe, no usb3, IDE disks, slow
network devices, etc.
Many people use virt-install in scripts and CI, and this may now
cause breakage. The environment variable is there to help them
get things back to normal as quick as possible, but it will still
noisy up their logs with the warning to hopefully get them to make
a useful change to their virt-install invocations.
This is limited to x86, since that's where most of our defaults
historically differ, and where we can depend on libosinfo to give
the most accurate device info. This may be relevant to change for
other KVM architectures in the future.

The canonical tool for this is `osinfo-query os`, which we still

However, we are about to make missing --os-variant fatal for common

to figure out what an acceptable --os-variant value is.

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

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.

This was raised here:

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
