Did some testing: if one pauses the vms that run windows before suspending
ubuntu no high cpu usage is there once the host and windows vms are resumed.
for me it's workable then in ubuntu by using a suspend / resume script with
power manaager. I put this in /etc/pm/sleep.d (and make it executable) :
#!/bin/bash
PS_VM=/var/run/paused_vms
is_there_virsh () {
if [[ -z `which virsh` ]]
then echo "no actions for suspend or resume required"
exit 0
fi
}
case "$1" in
suspend)
is_there_virsh
echo "" > /var/run/paused_vms
for i in $(virsh list --state-running | grep running | awk {'print $2'})
do echo $i >> /var/run/paused_vms
virsh suspend $i
done
;;
resume)
is_there_virsh
for i in $(cat $PS_VM)
do virsh resume $i
done
# optionally remove the file but this seems not required?
rm $PS_VM
;;
*)
;;
esac
