Libvirt: Enable Panic Device Notification
A Panic device has been introduced to QEMU and has Libvirt support since
version 1.2.1 Using this device, the guest can notify the host once a guest
panic has occurred, by sending an event to qemu, that in it's turn will notify
Libvirt. Libvirt has controls for how it can react to such an event; either by
restarting or shunting down the guest.
In addition, Libvirt has a mechanism to automatically save guest crash dumps
to a dedicated location on a host. Enabling the panic device for guest instances
will allows a crash dump of it to be taken, without the need of kdump running
within the guest.
If kdump and pvpanic are both enabled for the same guest, kdump takes
precedence over pvpanic.
