You CPU should support VT. I have a Pentium-D 930 and it supports VT and I've run KVM on it.

The trouble could be the motherboard. You need both to support VT in order to use the extensions. I have a Asus unit with a intel 945G chipset.

Look for BIOS settings. I beleive that sometimes BIOS upgrades can possibly enable the VT extensions so look fro a bios upgrade if you can't find any settings. By default the VT stuff was disabled in my BIOS.

The Pentium-D 8xx proccessors don't support VT, but the Pentium-D 9xx should.

The nice thing about Qemu + Kqemu and Qemu modified to support KVM is that images should work in both setups. Also they can run non-ported OSes (ie: Windows or SCO or whatever) were as Xen cannot without the VT extensions themselves.

But I do understand. I run Xen on my fileserver at home since it's just a AMD Althon XP. I have 2 nic cards, one is a Intel GB/s card and that goes to my lan, and then the onboard 100Mb/s goes to the 'DMZ' port on my Debian/Shorewall-based router. That way if the internet-facing server running in the VM gets compromised my home lan is still completely isolated. Good stuff. :-)
