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 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 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? -- Norman Gaywood, Computer Systems Officer University of New England, Armidale, NSW 2351, Australia ngaywood at une.edu.au Phone: +61 (0)2 6773 3337 http://mcs.une.edu.au/~norm Fax: +61 (0)2 6773 3312 Please avoid sending me Word or PowerPoint attachments.
