xm save lenny3 /tmp/lenny3.save
The guest console says: Suspending xenbus... and detaches.
Restore the guest (paused to attach its console before continuing):
xm restore -p /tmp/lenny3.save
xm console lenny3
xm unpause lenny3
The console starts spewing out "BUG: recent printk recursion" and the
domain spins until destroyed. The same thing happens on (live or not)
migration. The very same domains could be migrated without issues under
Xen 3.2 (more precisely, before I upgraded my dom0 to squeeze --
previously it was running lenny with the etch dom0 kernel for stability).
Migrating squeeze guests isn't a problem in the same setup (just replace
26-2 with 32-5 in the above config).
This looks like a regression. On the other hand, it doesn't seem to
affect a lot of people, because I couldn't find anything relevant on the
web. Please tell me if I can help debugging the issue further.

Thanks,
Feri.

Nope, it didn't.
Anyway, this is no bug in Xen, closing.
