Bug#600992: closed by maximilian attems <maks@debian.org> (Bug#600992: fixed in linux-2.6 2.6.32-27)
Greetings,
with the new kernel (*-27) the live migration completes without error on
the dom0 but on the domU migration from xen1 to xen2 works but whenever
I try the other way around the domU spits the following stack trace:
