One of my colleagues pointed out that this is a known bug. It will be fixed shortly. *** This bug has been marked as a duplicate of bug 915485 *** I apologize that 915485 is not public, but it's currently ON_QE. Just a note: switching from disabled to "permissive" allowed libvirt to start the lxc container. |
