Title:
  General protection fault kernel message from  qemu-system-x86

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  Basically, the system completely logged up when this happened, we can see the following trace on the console. Then we reset the box. The logs below are from /var/log/kern.log
  It's not reproducible at the moment. The issue happened when we tried to stop a VM (qemu-system-x86) hosted on the box via OpenNebula VM management web interface.

  Is there a way to figure out if this is a known issue that fixed on
  later kernel version?
