I tried it again and it happens systematically. I cannot start my VM. Last time I used it, it worked, and I could turn it off nicely. I'll file also a bug report on Linux, because if VirtualBox can cause the host OS to go down this way, no matter how bad the bug in VirtualBox, there's certainly something wrong in the host OS." defect closed host support VirtualBox 4.1.14 duplicate Windows Linux
