Package: qemu-kvm
Version: 2.1+dfsg-5~bpo70+1
Severity: important

Dear Maintainer,

first off, I am not sure whether this is the right package to report the
bug against. Feel free to re-assign as you see fit.

One of my VMs will not run correctly. Under circumstances which I have
not yet been able to pinpoint, the VM goes to 100% cpu and stops
reacting to about any input. I have to kill it hard (eg. "Force off" in
the virt-manager).

The problem occurred twice today, always under load in the VM. The
second time, it occurred while I tried to install a new kernel package
(see screenshots).

I have opened the console and saw a series of kernel oopsies floating
by. I have attached two screenshots, one from my SSH session, and one
from the console showing the kernel problems.

Here is a list of related packages that I have installed on my host:

Closing the bug, then.
