Couple of things to check and try.  I just ran into a nasty corner case
with Ubuntu running on a Fedora 20 host where the Fedora 20 system was
in selinux permissive mode and caused all kinds of grief in the Ubuntu
Trusty container.

Since your problem is Fedora on Fedora, check your selinux settings in
the host and in the container...

/etc/selinux/config
/selinux/enforcing

If they are NOT the same between host and container, make them the same and retest.

If your host is in "enforcing" mode or "permissive" mode, try switching
it to "disabled".  The Fedora template sets up containers set to
"disabled" by default.  I cringe at making that a recommendation but we
should, at least, test at that level.

Regards,
Mike
