Description Zbigniew Jędrzejewski-Szmek 2013-10-18 18:45:05 UTC 
Description of problem:
When terminating a qemu VM in virt-manager, host crashed.
On reboot I found the following in the journal:

*********** MASS BUG UPDATE **************

We apologize for the inconvenience.  There is a large number of bugs to go through and several of them have gone stale.  Due to this, we are doing a mass bug update across all of the Fedora 20 kernel bugs.

Fedora 20 has now been rebased to 3.13.4-200.fc20.  Please test this kernel update and let us know if you issue has been resolved or if it is still present with the newer kernel.

If you experience different issues, please open a new bug report for those.
