[Bug 350936] Re: Should shut down domains on system shutdown
Sorry for not writing that long, there was lot to do at work. My solution now for this problem is using a script that gets called by molly-guard, as testing other script-stuff was really annoying! As Molly-Guard installs it self as shutdown-command and executes each script inside /etc/molly-guard/run.d/ just before doing the real shutdown, it seems the perfect way for me on our server-system. I know it's just another workaround, but it's the least intrusive way and works very well because shutting down KVMs is done before all the other upstart/sysv-scripting stuff.

[Bug 350936] Re: Should shut down domains on system shutdown
As I'm currently setting up an intranet mail-server for my company
(based on lucid / ebox) in some kvm-guests and there for have exactly
the same problem. Reading all previous posts - and because I need kvm-
guest shutdown as well - I will use something like this:
Add following lines in /etc/init.d/sendsigs just before the sync line:
# avoid every running kvm (started thru libvirt-bin) from being killed
for pidfile in /var/run/libvirt/qemu/*.pid; do
OMITPIDS=${OMITPIDS:+$OMITPIDS }-o $(cat $pidfile)
done
I think this should prevent kvm-guests from being killed on shutdown.
Then in /etc/init/libvirt-bin.conf I would try to add following lines:
kill timeout 360
pre-stop script
# only shutdown all guests if stopping of task is because of
# runlevels 0 (halt) or 6 (reboot)
if [ $RUNLEVEL = 0 -o $RUNLEVEL = 6 ]; then
TIMEOUT=300
VIRSH_CONNECT=qemu:///system
function list_running_vms(){
virsh --connect
$VIRSH_CONNECT list | grep running | awk '{ print $2 }'
}
# send shutdown to each running vm (they must
handle acpi-power-button!)
list_running_vms | while read vm; do
virsh --connect
$VIRSH_CONNECT shutdown $vm
done
# wait until timeout has reached or no
running are vms left
END_TIME=$(date -d $TIMEOUT seconds +%s)
while [ $END_TIME -lt $(date +%s) ]; do
test -z $(list_running_vms)
break
sleep 1
done
# if any vms left running destroy them now
if [ -n $(list_running_vms) ]; then
list_running_vms | while read
vm; do
virsh
--connect $VIRSH_CONNECT destroy $vm
done
fi
sleep 3
fi
end script
I don't know yet if this works, but I will test as soon as possible.
Maybe if somebody else is in the mood to do so please report if it
succeeded...
