Hi All, Recently i have started using tool (lxc-0.4.1.tar.gz) for container creation released by Daniel. I am not sure if inside container cgroup support is there or not. If it is not supported till now then here is the point where we can start to look into it. Steps executed: - Executed following command on host: mkdir /cpu mount -t cgroup -ocpu cgroup /cpu mount umount /cpu mount After executing above commands you can see mount will not show extra mounted file as: cgroup on /cpu type cgroup (rw,cpu) But If the same thing you do inside container, you will be able to see this line (cgroup on /cpu type cgroup (rw,cpu) ) still with mount command. - create a container : lxc-create -f /etc/lxc-no-netns.conf -n xray rishi :~ # cat /etc/lxc-no-netns.conf # Container with non-virtualized network lxc.utsname = delta - Execute container :~ # lxc-execute -n xray /bin/bash delta:~ # - Execute the following command inside container delta:~ # mkdir /cpu delta:~ # mount -t cgroup -ocpu cgroup /cpu - delta:~ # umount /cpu delta:~ # mount ... cgroup on /cpu type cgroup (rw,cpu) cgroup on /cpu type cgroup (rw,cpu) cgroup on /cpu type cgroup (rw,cpu) delta:~ # umount /cpu umount: cgroup: not found umount: /cpu: not mounted umount: cgroup: not found umount: /cpu: not mounted umount: cgroup: not found umount: /cpu: not mounted umount: cgroup: not found umount: /cpu: not mounted delta:~ # As i can understand cgroup has been mounted and unmounted inside container so it should delete the mount entry also. And also you will be able to see from host too .
