Thanks for doing this, I just gave it a try and it worked out of the
box, I was able to create and launch a Windows VM in less than 2min,
quite impressive :).

I've given a look at the patch, but I have to admit I know very little
about UUID, yet it seems like you should not poke directly at the
internal uuid_t fields. I've created another patch which I *think*
should solve the UUID issues, could you test it please? It should apply
cleanly against Xen 4.5.

I haven't seen this, but I'm not surprised (I also don't have a 10GbE
card at hand right now). There's a lot of fine tuning and bug fixing to
do regarding the backends. I plan to get with this once the PVH
implementation is stable.
