So it seems it has been a problem with virt-v2v conversion, because if I
shutdown the VM and set it to Windows 2008 R2 x86_64 and optimized for
server and I run it, I get this flag for the cpu:

-cpu Westmere,vmx=on,hv_time,hv_relaxed,hv_vapic,hv_spinlocks=0x1fff

BTW: what are the other flags for:


hv_spinlocks=0x1fff
hv_relaxed
hv_vapic
?

Complete command is:
