No, it's because libvirt doesn't handle all the tiny small details
involved in specifying a CPU. All libvirty knows about are a set of CPU
flag bits, but it knows nothing about 'level', 'family', and
'xlevel',
but we would like to allow it to expose a Westmere-like CPU to the
guest.
This is easily fixable in libvirt - so for the point of going discussion,
IMHO, we can assume libvirt will support level, family, xlevel, etc.
