I'm sorry, my brain was addled from staring at spinlock code too long.
Of course, since the domU is PV you already have MFNs. 

In that case, I can't think of any obvious reasons for the failure.
you'll just have to dig a bit further -- see exactly which entry it's
complaining about, whether it matches what the dom0 tools thought they
put there, and what you would expect to be there.

Cheers,

Tim.
