So, the branch candidate/xenpv-support is a little bit old. I did not
update this branch since a while.

But if you just want to run HVM guest, you could use "my" branch
"xen-next", as it will be merge (soon I hope) in qemu-uptream.

If you need the patches in candidates/xenpv-support, eithier merge it
or cherry-pick the patch ;).
