This is a warning that we will not be able to report some of the stats that we only get from docker using the libcontainer exec driver. You should still be able to see regular cpu, memory stats, but they show under "subcontainers" rather than docker containers (eg. /lxc container in the logs above).

You can ignore these errors if the stats you are interested in are still showing up.

Yes, I manage to make it work, We use docker with option bridge=none and
setup our own bridge and specify part of lxc, once I remove this option it
works as you explained.

If you got any insights why we could not work would be gr8.
