[libvirt] auto shutdown for qemu / kvm

[Matthias Pfafferodt]

Hello,

there is the possibility to autostart a (qemu/kvm) domain. If libvirtd is 
stopped this domain is killed and the filesystem is in a unclean state. I 
miss the possible of an 'autostop' option that will shutdown a (qemu/kvm) 
domain if libvirtd is stopped.

I changed the init script of my system (opensuse 11.0) to implement 
the 'autostop' option. Is there a simpler solution? Do you have tips how to 
improve the script?
