Description of problem:
I was attempting to launch a vagrant libvirt instance (for OpenShift Origin)
SELinux is preventing qemu-kvm from 'write' accesses on the fifo_file fifo_file.

*****  Plugin catchall (100. confidence) suggests   **************************

If you believe that qemu-kvm should be allowed write access on the fifo_file fifo_file by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# grep qemu-kvm /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
