This is a virt-xml option to refresh a VM to use the latest machine
type version for the machine type it's currently using. Ex:
pseries-2.11 -> pseries
pc-q35-5.0 -> q35
This is useful for when qemu deprecates and removes the machine type
out from under you, or to pick up bug fixes.

We enable default graphics for all of ppc64, but really the only
thing we have ever tested is pseries, so make that clear.

This reverts commit 20d3bf9484.
Indeed graphics does work on aarch64, but for example, fedora
server aarch64 installs don't output any graphical output and only
put data on the serial console. So we would need to be more specific
about how we enable this if we make the change.
qemu 6.1, fairly new when we added this option, has an unfortunate
bug with >= 15 root ports, so we choose 14 instead of our original 16

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.

If the user selects virtiofs when editting or adding a new VM, and
we don't detect that they have shared memory enabled, show
a warning label in the UI pointing them to the Memory screen.
It would be nicer if we did this for them, but to get that totally
correct would require both duplicating libvirt's shared memory
detection logic, and some surgery to the addhw wizard. This is good
enough for now

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.

Add extra PCIe root ports to enable q35 device hotplug to work out
of the box. A typical modern linux guest has 7-8 PCI devices added
by default, so this gives plenty of wiggle room.
The smart thing to do would be to count the attached PCI devices
and add 4-5 extra, but that takes more work and isn't trivial.
The number can be overridden on the cli with:
--controller q35_pcie_root_ports=X
Use =0 to go back to the old behavior.

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.

Historically over time it's been more likely that an issue is reported
for osinfo-db missing the usb-tablet annotation. So for example we
always enable it for the default 'generic' case. We also want to
enable it for osinfo's 'unknown' case too.
Rather than add another check for that, let's just drop the osinfo
checking entirely. Some very old OS don't support usb-tablet, but
specifying it for those cases doesn't cause issues AFAIK, and users
can override it with `--input none` if they want.
Signed-off-by: Cole Robinson <crobinso@redhat.com>
Currently we skip the warning if the user explicitly requests
`--osinfo generic`. Upcoming changes to the defaults here will make
it tempting to specify `--osinfo generic` just to make things work,
and we want to dissuade that, so enable the warning for that case too.
