This patch series adds support of auto-dump on watchdog event in
libvirtd. If a qemu guest is configured with a watchdog device and
libvirtd receives a watchdog event from the guest, it can do
something on the guest, currently `dump' action is defined.
This patch series adds a new watchdog action `managed', it has a
subaction wich indicates the action libvirtd will take on a watchdog
event.
The meaning of subaction_arg depends on subaction. If subaction is
`dump', then subaction_arg defines a folder path into which libvirtd
saves dumpfile.
An example:
<watchdog model='i6300esb' action='managed' subaction='dump' subaction_arg='/mnt/data/dumps'>
In order to make the function work, there must be a watchdog device
added to guest, and guest must have a watchdog daemon running, for
example, /etc/init.d/watchdog start or auto-started on boot.
Suggestions are welcome!
