Hi,
I've got a pair of Xen hosts with different dom0 kernel versions.
Some domain is running on the 2.6.18 dom0. The other dom0 runs a
2.6.26 kernel. If I live migrate the domain to the other, I get lots
of "(XEN) grant_table.c:1381:d0 destination frame 7fffffff invalid."
messages on the console of the new host, and the migrated domain goes
unresponsive. However, I can migrate it back, and then it springs to
life again with the following kernel logs:
[ 6409.387774] suspend: event channel 8

Is migrating between different dom0 kernel versions something I
shouldn't dream of?
