GNOME Boxes can't start a VM anymore
Submitted by Alberto Ruiz
Link to original bug (#769308)
Description
I just had a situation that I can't reproduce but that I've encoutered a few times, basically Boxes is unable to connect to a specific machine anymore even though virt-manager can turn it on and off.
Once I enter the vm the spinner keeps going forever and these 4 threads keep starting and stopping.
I tried to attach to the app but the backtrace doesn't look very helpful:
