Just wondering if this is a known bug?

Trying to migrate the VM off to a diff dom0 results in the below error. Other VMs migrated off fine (started at around the same time as this vm) and I've tried a few different target servers, all resulting in the same thing.

xend-debug.log and the target dom0 logs don't show anything of value.

This is xen 4.1.1 on linux 3.0.3
