[Users] Guest life-cycle

Hi, after being able to start my first guest I noticed two things: 1) When I started the guest with the "run once" option the console button didn't become available. Navigating to another section of the GUI and back didn't help. I was only able to make is available by closing the browser tab and then going to the admin portal again from scratch. 2) When my guest froze (due to nested virtualization experimentation that apparently doesn't work yet) I had no (obvious) way to kill the vm. Hitting the stop button apparently only sends a shutdown command but I couldn't find any way to issue a destroy command. After killing the qemu process on the host manually the guest in the portal gui apparently went into an unknown "?" state which isn't surprising but now there seems to be no way to get rid of the vm. What is proper way to get rid of such a misbehaving guest? Regards, Dennis
