Just spotted this in the new shared VMs options. I've always been a little unsure what happens to a shared auto-start VM when you shutdown the host in v12. I was pretty sure that it suspended the VM in that I tested it where the console was logged in and after restarting the host, it was still logged in.
So I assume this new options just enforces that process. But what happens if the box is unchecked? Is the VM shutdown and then restarted after reboot?
Will do a test...
