[Bug 350936] Re: Should shut down domains on system shutdown

[Francesco Pretto]

I'm not sure it can be done hacking upstart job. When libvirt was a
sysvinit script in ubuntu 9.10, I used this [1] script adding it in
"stop" function. In Lucid, if I add the same script to /etc/init
/libvirt-bin.conf with the stanza:

pre-stop exec shut-guests.sh 2>&1 > /var/log/shut-guests.log

This works if I manually invoke a stop of libvirt-bin in a running system with:
$ sudo stop libvirt-bin

but **doesn't** work when issuing a reboot or halt. It seems there's an
aggressive killing of all kvm processes **before** the pre-stop stanza
is execute, and libvirt doesn't find any running guests when the shut-
guests.sh is executed. it's not clear to me why and If this is an
exptected behavior. For sure, kvm processes are detached from libvirt
process branch.
