Then if you kill this windows guest, does dom0 come back normal?
If yes, it's possible due to servicing windows guest activity such as
heavy disk i/o as you guess. If not, it may indicate some hang condition
happening either within dom0 and Xen, and then you may first find out
the hang point and then dig into for detail. Also it'd be good to check
both dom0/xen dmesg to see any warning reported already.

Thanks,
Kevin
