LXC/cgroups process group scheduling in linux 3.18+

Hi, Apologises if I am asking a dump question. Is there any support for container(lxc/cgroups) scheduling in linux scheduler(3.18+). I want to use only unprivileged containers. Basically I want to give more priority to processes in a container(basically to app in the container). Can we use RT scheduling?. one more question is how process scheduling happens inside the container(lxc/cgroups), is it like for some time(till the next container is selected), only processes inside container(lxc/cgroups) is scheduled? Thanks
