I see. There shouldn't be much differences, from a credit scheduler
point of view (and even more so wrt the caps) between 4.2 and unstable.
Anyway, just to rule out all the possible doubts, can you build and
install unstable on your box?

What about the guest? PV or HVM? What's running in there? In my case it
was a PV guest, also running a Debian unstable, and using the same
kernel dom0 does.

Regards,
Dario
