[libvirt] [PATCH 2/4] PowerPC : Forbid NULL CPU model with 'host-model' mode.
PowerPC : Forbid NULL CPU model with 'host-model' mode in qemu command line.
This ensures that an XML such as following:
...
<cpu mode='host-model'>
<model fallback='allow'/>
</cpu>
...
will not generate a '-cpu host,compat=(null)' command line with
qemu-system-ppc64.
