Formally we support running Xen on any x86 hardware supporting 64-bit
mode. I don't think I have any 1st gen systems left, but I think a
2nd gen SVM and a 2nd gen VMX one is what I still have around.

Because as part of my job I also need to support ancient versions of
Xen on ancient distros. Since I need to keep those around, it makes
sense to me to then also test modern Xen there (every now and then, as
said, and not really extensively).
