Maybe you don't have xenfs mounted so virt* stuff can't figure out the
hypervisor info?

Do you have /proc/xen ?  yes i have

Do you have this line in /etc/fstab:
none            /proc/xen       xenfs   defaults        0       0
this was missing, add it now

Also, please update to 'xen/master' branch, and you'll get 2.6.31.4
based pv_ops dom0 kernel.
Okey thanx alot i will surly giv it a short
2.6.30-rc6 you're running is not supported, and a lot of bugs has been
fixed after that version.
