PV-GRUB is really awesome, however I noticed that it spins at 100% cpu, 
even while just sitting at its prompt.  Just a heads-up...

Thanks,

The problem comes from GRUB. I thing even on a real machine GRUB takes
all the CPU.

Yep.
We could path the src to make it issue a block hypercall with a 100ms
timeout...
