Conceptually, sure.

Plain qemu ought to work today.

Running KVM in an HVM guest would required nested HVM support in Xen
(i.e. the ability to expose hardware virtualisation features to HVM
guests). This is currently only available as an experimental feature in
xen-unstable, I expect it will be released only as an experimental
feature in 4.2 as well. KVM on Xen was one of the cases tested by AMD
http://lists.xen.org/archives/html/xen-devel/2012-03/msg00883.html

Running KVM in a PV guest I'm not sure about, conceptually possible I
suppose but not possible in practice today AFAIK.
