[ovirt-users] kvm vcpu0 unhandled rdmsr

[gregor]

Update: The problem occur when a VM reboots.
When I change the CPU Type from default "Intel Haswell-noTSX" to
"Westmere" the error is gone.

But which CPU type is now the best so I don't lose performance.

Host CPU: Intel(R) Xeon(R) CPU E5-2603 v3 @ 1.60GHz
