Comment 1 Mairi Dulaney 2014-08-19 18:34:31 UTC 
Proposing as a beta blocker bug under the  Self hosting virtualization criteria.
Comment 2 Daniel Walsh 2014-08-19 20:21:45 UTC 
What AVC's are you seeing?

Looks like you need to turn on the virt_use_execmem boolean.

I think we can fix this long term if we just change libvirt to use a different type for containers running with qemu-kvm versus qemu-system
Comment 3 Daniel Walsh 2014-08-19 20:23:02 UTC 
This works the same way in Fedora 20 BTW, so it is not a blocker.
