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...
