next question: is cache leaf forwarding a migration blocker?
"-cpu host" in general is "interesting" at migration time, so I would
say no.
It works for for a long time as long as all cpu features that are supported on
the source
are also supported on the destination.
As for the cache leaves feature I would go for making it a optional parameter.
If we
woudl want to support it, we need to adjust several cpuid indexes to reflect
the emulated
cpu topology. Question would be to what extend the cache information would then
make sense. Or with other words if one wants to use cache leaf pass-thru the
topology
must match the physical one?
