Can we disable write to /sys/fs/cgroup tree inside container ?

This is really strongly recommended against. It is better to mount each controller separat...

RHEL6 cgroup error after a few days of uptime
I have a RHEL6 that hosts many kvm virtual machines. It has been working fine for a couple years. I apply errata updates about once a week. In the last couple weeks, I've ran into a bug where the virtual machines start failing to start with a cgroup error message. If I reboot the host (very disruptive) then things start working normaly for a few days. Can I configure qemu/libvirt not to use cgroups at all as a temporary workaround? How would I do that? Here is example of trying to start a vm (that hasn't been started since boot) after th...

How to deal with LXC cgroup access control with apparmor ?
I am playing with libvirt 1.1.1 (lxc) when I was starting a LXC container, the process location of cgroup is pretty , just the root directory from the process. But I could tune the cgroup in a container as an user that logged, This is not accepted... I wonder how to restrict it with apparmor ,so one can not modify files in the cgroup fs, e.g the cpus or mem, if i restrict it with "deny /sys/f...

Re: cgroup error starting domains
Tried with commenting out cgroup_controllers but with no change. Tried also unmounting /sys/fs/cgroup and mount the cgroups in a subfolder hierarchy manually but it remounted still all together (I think this is related at the unmounting support going away, I'm with kernel 3.10-rc4 on the test machine). So I had a look at Sla...
