I'm running Xen on Athlon 64 and wanted a debian VM. The quick and dirty
approach I took was to install debian in vmware, shut it down and open the
debian disk in a SuSE VM I then used DD to get the disk into a image file. I
mounted the debian image as a loopback filesystem and copied the SuSE xen
kernel modules into the disk image. I then booted the debian image using the
SuSE xen kernel and initrd with xen.

I had to hand craft the xen config file for the VM but I'm getting used to
that now.
