See bug 999926 for the selinux fix. (In reply to Daniel Berrange from comment #6) > See bug 999926 for the selinux fix. Thanks for your quickly reply. bug 999926 fix in selinux-policy-3.12.1-73.el7, but i update selinux-policy and restart guest, the permission deny error still there. Please help to confirm this, thanks very much. If you are still getting an AVC, then please provide an update on the selinux bug rather than this one. The AVC you list in comment #5 is the one the selinux bug is supposed to fix.
