Description James R. Leu 2013-05-28 13:11:42 EDT
Description of problem:
redhat 6.4 kernel does not support /sys/fs/cgroup but /cgroup does exist in the LXC. systemctl does not work without /sys/fs/cgroup and systemd cannot shutdown without /sys/fs/cgroup

Version-Release number of selected component (if applicable):
In the LXC:

How reproducible:

Steps to Reproduce:
1. create fedora17 LXC on redhat 6.4 host
2. run systemctl

Actual results:
Failed to get D-Bus connection: No connection to service manager.

Expected results:
systemctl should list systemd services/targets

Additional info:
Is there a way systemd can use /cgroup if /sys/fs/cgroup does not exist?
Comment 1 Lennart Poettering 2013-06-04 07:49:02 EDT
Sorry, but we do not support these old kernels with systemd.
Comment 2 James R. Leu 2013-06-04 08:11:38 EDT
Lennart, I've read the original bug report where you rant on and on about not
supporting old non cgroup kernels.  I would like to point out that my use case is RedHat's bread and butter for the future - virtualized desktops (Fedora 17 LXC) on a RHEL 6.4 host.  Not only that, but all that is needed is for systemd to look for /cgroup as opposed to /sys/fs/cgroup.  I understand you've 'put your foot down' but I'm not sure you should be speaking on behalf of a $1bn company especially in such a huge growth area as desktop virtualization.  As a long time user of RHEL on over 500 systems, your standpoint does not make business sense.
Comment 3 Lennart Poettering 2013-06-04 09:05:22 EDT
It's really no that simple I fear. The mount point change is one among many things we require from modern kernels. You will run into many similar issues pretty quickly.
