That's a good question, I'm not really sure. I'm doing all the vm
creation/migration/shutdown using libvirt 0.9.0 rc1 and just connecting
with xen:/// to the local xend.  I thought xl was just a userspace
replacement for xm and the backend functionality was the same?

I don't have a spare server to test the patch with at the moment, but I
can try this out later this week.
