[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!
