reboot guest on panic
...rashing and want to automatically reboot it
when it crashes. See:
xen PV guest kernel 2.6.32 processes lock up in D state
https://bugzilla.redhat.com/show_bug.cgi?id=550724
if you want to look at the details on the crashing.
Anyway, I boot the guest with the kernel command line parameter:
hung_task_panic=1
I have kernel.panic = 15 in the guest /etc/sysctl.conf
In the guest config file in dom0 I have:
on_poweroff = "destroy"
on_reboot = "restart"
on_crash = "restart"
The guest manages to panic when it detects the hung tasks and I get this
on the guest consol...

CTDB problems
Hi,
This morning our CTDB managed cluster took a nosedive. We had member
machines with hung smbd tasks which causes them to reboot, and the
cluster did not come back up consistently. We eventually got it more or
less stable with two nodes out of the 3, but we're still seeing worrying
messages, eg we've just noticed:
