Description Dr. David Alan Gilbert 2016-04-11 16:06:20 UTC 
Description of problem:
This is a nested VM; host is T530/F23/4.4.6-301.fc23 kernel/qemu-kvm-2.4.1-8.fc23
Guest is f24 daily (dated 9th April).

Crash occurred while installed the L2 guest (again with the f24 daily).
I've done it a couple of times before and it's been OK; so not that repeatable.

reporter:       libreport-2.6.4

*********** 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 24 kernel bugs.
 
Fedora 24 has now been rebased to 4.7.4-200.fc24.  Please test this kernel update (or newer) and let us know if you issue has been resolved or if it is still present with the newer kernel.
 
If you have moved on to Fedora 25, and are still experiencing this issue, please change the version to Fedora 25.
 
If you experience different issues, please open a new bug report for those.
