Sure, but this was not the purpose of this patch. Currently KVM guests
see a CPU type which is TCG dependent, so I just wanted to get rid of
this. Features of TCG and features of the host processor are totally
uncorrelated. This new type should be KVM's default, leaving -cpu host
as the alternative for the non-migration case.
I think this is best left to management software, which has more
information about the migration pool.
Sure.
