Comment 8 for bug 350936

Workaround:

Add the lines:

        /usr/local/bin/shut-guests.sh 2>&1 >> /var/log/shut-guests.log
        /sbin/initctl emit guests-shutted

just after "do_stop() {" in /etc/init.d/sendsings

*and* changing the line:

stop on (runlevel [!2345])

on file /etc/init/libvirt-bin.conf to:

stop on guests-shutted

Ugly but works, until libvirt/kvm/distributions crews will care more about data integrity in vm guests during shutdown (sigh).
