If there is something to fix in dbus, please mention what it is. The numeric ID for the denial should be fixed with the changes in bug 1364485. We need to allow systemd_machined_t domain to communicate with lxc container via dbus. Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA. For information on the advisory, and where to find the updated files, follow the link below. If the solution does not work for you, open a new bug report. https://rhn.redhat.com/errata/RHBA-2016-2283.html |
