Some observations: - this has nothing to do especially with devstack, this also happens e.g. on f18. - it is caused by quantum calling internally ip netns exec - ip remounts /sys and destroys /sys/cgroups - systemctl tries to access /sys/cgroups and returns that misleading error message: Failed to get D-Bus connection: No connection to service manager. - no ability to shut down the system cleanly anymore. So, I think, these are at least two errors: - ip remounting /sys and destroying the hierarchy below that mountpoint - (at least) misleading error message from systemctl. My proposal here would be to try to remount /sys/cgroups etc. because this error might happen even by accident Matthias -- Matthias Runge <mrunge@xxxxxxxxxxxxxxxxx> <mrunge@xxxxxxxxxxxxxxxxx> _______________________________________________ cloud mailing list cloud@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/cloud
