What happens if you use non-live relo?
I thought I had tested that way back at the beginning without seeing the
problem, but I must not have, because I just retested it to be sure and
it died the same way. (Now I am truly confused and I need to go back and
re-examine some of my earlier experiments.)

In the meantime, any ideas where to look?

This will be very dependent on the guest that is being migrated. What Linux
kernel is the domU running?

 -- Keir




Linux 2.6.16.29 (+ the SLES 10 iscsi patches) with approximately the config used by the SLES 10 Xen kernel.

I can send the config, if you need it.
