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.

Did you try xm save -c (or the xl equivalent) ? This should be
activating the same
code path where this error seems to appear.
Also, make sure you have CONFIG_XEN_SAVE_RESTORE enabled.

All the dom0's are 3.0.3 and all the domU's are 2.6.32.27 (w/ grsec).
I did a cold reboot of the VM and now it migrates properly.

Unfortunately I didn't think to try it. I do have that set on both dom0
and domu.

Oh, I assumed that the domU's were linux 3.0.3. That config has no meaning
for dom0s.
