Title:
Sudden hard reset (reboot) caused by VirtualBox
Status in linux package in Ubuntu:
Confirmed
Bug description:
Starting from today, whenever I (try to) start a virtual machine in
VirtualBox, the host system suddenly reboots without warning, without
even shutting down.
There's certainly some bug in VirtualBox, but if a program, no matter
how buggy or even malicious, can cause the whole operating system to
reboot suddenly, there's by definition some very serious bug in the
operating system itself.
WORKAROUND: Disabling 3D _and_ 2D acceleration in the virtual machine
fixed the issue.
