Libvirt Watchdog

Registered by Daniel Berrange on 2013-02-13

Libvirt has the ability to configure a watchdog device for KVM / QEMU guests. This device can be used by the guest OS to automatically trigger some action when the guest OS hangs/crashes. This is useful to cloud users to deal with problems in their guest OS, to kill off a mis-behaving instance to allow an external HA solution to move processing to another instance.
