Re: Lost of performance over AMD-V with KVM?

Yep,

     -> this is for the host:

     root@vfalbor-desktop:~# cat /proc/cpuinfo | grep flags | uniq
     flags        : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge 
mca cmov pat pse36 clflush mmx fxsr sse sse2 ht syscall nx mmxext

     -> this is for the VM:
