I have had good success with OpenVZ, but if you intend running that on a
destkop machine with an X GUI and all you may need to have experience
building and configuring your own kernels.[1]

It has the key advantage that you run only one kernel and hardware
interface; it gives you the equivalent of a "super-chroot" that allows
the other VM to run with minimal overhead.

I only use it on servers, but this mail is passing out via one of them.

Regards,
        Daniel

Footnotes: 
[1]  At least some of the OpenVZ kernels didn't have sufficient support
     for sound and DRI to qualify as "desktop" by most definitions.
