[libvirt] libvirt-guests.sh stop

Hi all, the shellscript causing VMs to eventually stop when the host shuts down/reboots has a window where it can loose ACPI shutdown events. I have seen VMs not shutting down before they become ACPI aware, causing the systemd magic to time out for a couple of minutes and eventually killing the VM. Steps to reproduce: - start a new VM - reboot the host while the VM is still booting up What happens: - the ACPI power-button event will get lost - the systemd loop on the host will go and wait - the VM will get killed hard eventually What should happen (probably): - the retry loop should inject an ACPI power-button-event with every retry (5s?) - the VM will eventually have ACPI support and pick up any of the many button-events - the VM will shut down on any of the many power-button events, if there was enough time I could try to come up with a patch, but i hope the description of the problem is clear enough so someone else will try. regards, Henning
