There's been various discussions about changing the x86 default
from 'pc' to 'q35' over the years, but it's unlikely to happen
at the qemu or libvirt level for compatibility reasons. So
let's start using it for new enough OS that support it.
Now we have only one Installer class, and callers don't need to
worry about choosing a particular class type depending on their
needs, just pass cdrom vs. location to the installer init and
we figure out everything behind the scenes.
Besides simplifying the callers this makes the control flow a
lot easier to follow whether looking at InstallerTreeMedia or
Installer classes
With another fake iso, based on stripped down centos 6.5 boot iso.
Reason we do centos 6.5 is that everything newer also compares
on volume size, and we don't want to store a huge iso in git.
virt-install -n blah -r 1024 --vcpu=1 --disk=/root/vm/blah.qcow2,size=10\
--network=bridge:br-public --pxe --boot=network,rebootTimeout=3
By default, in case of (first) pxe boot failure the VM will simply
stop trying.
By adding the above, VM will re-try pxe boot. ( useful when DHCP not
replys on first attempt.
Libvirt support it and VM XML will look as follow : ( 'bios rebootTimeout'
will be created under OS section. )
<os>
<type arch='x86_64' machine='pc-i440fx-rhel7.5.0'>hvm</type>
<boot dev='network'/>
<bios rebootTimeout='3'/>
</os>
(crobinso: fix it, add test case)
Allow to set some memory backing options, ex:
--memorybacking access_mode=shared,source_type=anonymous

libvirt will use rtl8139, but the qemu default changed a while
ago to e1000, and libvirt has diverged. e1000 is more modern and
considered the better default here, so use it
Don't rely on libvirt's default. This makes any XML changes more
explicit, and can help other parts of the code that may depend on
a machine type being encoded
We shouldn't concern ourselves with whether the OS supports qemu_ga
out of the box, just set up the channel regardless, as long as
virtio-serial is supported.
This adds the channel for some aarch64 cases which didn't have OS
specified, but that's desired IMO
This case will still work, but be a bit slower, which is fine. Nowadays
-M virt is much better for virt usage and nearly everyone is using that,
so save us the complication. This was really only useful when
bootstrapping arm virt support
Let libvirt/libxl fill it in. This was required for rhel5 xen at
least, but we don't support that anymore and modern libvirt seems
to do the right thing and fill it in for us.
The validation is already handled by libvirt, and setting q35 for
smm=on is overkill and just hardcoding some libvirt logic here.
I think the 'secboot' detection in Guest.py is the preferred
magic here, otherwise let users specify all the correct values.
An emulated backend doesn't require any path, since libvirt will take
care of finding the emulator and managing the storage. However, the
version to emulate can be specified.

Add codec support to virt-install so that it can accommodate
multiple instances of codec configuration.
The commandline argument:
--sound codec0.type=micro,codec1.type=duplex,codec2.type=output
maps to the sound XML below:
<sound model="es1370">
<codec type="micro"/>
<codec type="duplex"/>
<codec type="output"/>
</sound>

Lookup the domain capabilities CPU model and compare with
the host capabilities CPU model and if they are not equal
set the guest's CPU model to None.
(crobinso: compare against 'custom' list not 'host-model', move
to separate function)
non-treeinfo redhat only applies to pre RHEL5.4 and very old
Fedora. It's not worth it anymore to slow down all URL lookups
and maintain code complexity to handle such long out of date
distros.
GenericDistro doesn't actually apply to any public trees that I
can find, except for some with TreeInfo. So turn it into
GenericTreeinfoDistro. If random URL trees want to work with
virt-install, add a treeinfo file
