I have a guest that keeps crashing and want to automatically reboot it
when it crashes. See:
xen PV guest kernel 2.6.32 processes lock up in D state
if you want to look at the details on the crashing.
Anyway, I boot the guest with the kernel command line parameter:
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 console:
Kernel panic - not syncing: hung_task: blocked tasks
Rebooting in 15 seconds..
However, it never restarts. It just hangs around until I do a
xm destroy <guest>
xm create <guest>
Have I missed something?
