[kubuntu] Change default 'shutdown' to 'save state' in virt-manager on host shutdown

Right now I have a VM set to start at boot, but when I reboot or shutdown it tries to do a shutdown within I think 110 seconds. This works at the moment, but before long I intend to have an app running in the VM that'll interrupt a graceful shutdown indefinitely.

So I'd like to find a way to set this one guest VM OS to save state rather than shutdown upon host shutdown. The either boot fresh or restore saved state upon the host's booting up.

I don't see any way in any settings in virt-manager to make this change. Is there a way?

Thanks...
