I fail to see how this is caused by cgroups. They seem to be setup correctly. The eexist on last error is only happening because a prior container start failed and the cgroups did not get cleaned up properly.
Clearing out the cgroup files did not alleviate the problem. Also upon the first run of the container after boot, there were no such errors as the files didn’t exist.
I might be able to set up a test machine at some point, but I’m fighting fires left and right here right now. Thanks for your reply.
Then what’s the startup failure in that log? That’s the only thing that appears to cause an error and tear down.
Here’s the full trace I have from when I attempted to start a stock Ubuntu container after having purged the cgroup dirs that it was complaining about in the other logs:

Yeah, I’m looking at the liblxc code and trying to figure out where it fails and why we don’t have an error message.
@wdelgenio can you check that this is not segfaulting, please.
I saw no core dumps when I was working on this, so I don’t believe there were any segfaults. Can’t be sure, but I no longer have the CentOS environment to test.
Hm, so for the container. It uses macvlan. Does the interface eth0 exist?
Yeah, that’s not it.
Here’s the log from 3.0.4 before I did the echo 1000 > /proc/sys/user/max_user_namespaces and unshare -U and unshare -m

I did eventually get that working-gopher container to run on 3.0.4
I really can’t explain the error at the moment. The only thing that comes to mind is a segfault.
Hi everyone,
I recently encountered a very similar problem, the containers did not start with the same error that the TS @wdelgenio indicated. In my case, the cause of the problems was commonplace - time desynchronization on cluster members. One of the servers was 10 seconds lag due to an ntp configuration error. After correcting ntp settings the containers were created and launched without problems. Maybe this will be useful to someone 
Too many dependencies on all the nodes working exactly 100% correct for the cluster to work well. We have seen one bad server cause lots of issues for the whole cluster.
