Comment 41 for bug 1580459

I managed to fix that issue and properly load the VM with the rom file (what had gone wrong was it inexplicably acted like it had no hard drives, until I restored the libvirt XML file from a backup). I got a good test out of it: played video games in Windows for 2 hours, with the rom file loaded. It still froze on shutdown. So that's confirmedly not a fix.
