Hi,
CPU-Host support allows the virtual machines to see and utilize the host's CPU flags,
this enables better performance in VM's, at the price of worse portablity.

Your feedback is welcome!
Thank you,

- I assume that when you allow migration, you'd use host-model? This is
not clear from the design. It seems like we VDSM developers can choose
to use either this or passthrough, while in practice we should support both.
- I'm still convinced and commented on both relevat oVirt and libvirt
BZs that we need to add x2apic support to the CPU, regardless of what
the host CPU exposes.
AFAIK, the KVM developers agree with me.
