Title:
  crash with Ubuntu12.04 64bit guest on Ubuntu12.04 64bit host

Status in “linux” package in Ubuntu:
  Confirmed
Status in “qemu-kvm” package in Ubuntu:
  Confirmed

Bug description:
  I am on Ubuntu12.04 64bit updated to 7.4.2012.

  On this platform I am using qemu-kvm1.0 with virt-manager(?->latest).

  I have had runned a Ubuntu12.04 guest in this configuration. On
  newstart sequence to finishing updates of the guest(new kernel
  verison) the guest vm crashed.

  A .crash file was gathered in /var/crash/ for this, but apport failed
  to report it and crashed itself:

  https://bugs.launchpad.net/ubuntu/+source/apport/+bug/975832

  The .crash file of the qemu-kvm issue is above 600MB of size, which
  may be the cause for apport failing.
