Finally had a chance to test this. The patch itself looks okay;
however, on an actual POWER9 host, I get
qemu-kvm: can't apply global
host-powerpc64-cpu.compat=power9: Invalid compatibility
mode "power9"
and
qemu-kvm: Compatibility PVR 0x0f000004 not valid for CPU
when trying power9 and power8 compat modes respectively.
David, are these known issues in QEMU? Are they being tracked?
I don't see much point in updating libvirt to cope with these
new compat modes when QEMU itself doesn't.
