[libvirt] [PATCH 0/2] Support of auto-dump on watchdog event in libvirtd



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!
