Windows Guest: CPU description

[BiagioParuolo]

Hi,

my windows guest display qemu cpu, but I see this image from kvm site http://twitpic.com/dxs0z/full that is possible to display real host cpu.

How is possible this? There is some setup to do into ProxMox?

Thanks

Hi,
you can use the args-argument in the vm-config. The avaible cpus you get with

kvm -cpu ?

I think "args: -cpu host" is this where you are looking for.

Hi,
because this
a) only live-migrate between same CPUs - not recomended, but work normaly well
b) if you start your vm on a other system (different CPU), you have an good chance that windows ask for a new registration due hardware-changes - this won't nobody
