I think this is when it's trying to DESTROY the devices before
restarting the guest - which isn't, as you say, particularly critical.

Try doing a "gdb" and "attach nnnn" where nnnn is the process id fo the
QEMU-DM that is running at 100%. I don't guarantee that you'll find
anything useful, but I guess this will at least tell you where qemu-dm
may be spending it's time [this assumes you understand a bit about
running gdb - if this doesn't mean ANYTHING to you, then you're probably
not suited to try this].
Can you remind me which version of Xen this is?
