This is really strongly recommended against. It is better to mount each controller separately at /sys/fs/cgroup/<controller name> and have /sys/fs/cgroup as a tmpfs. http://www.freedesktop.org/wiki/Software/systemd/PaxControlGroups eg to get something alo...

No, systemd is definitely /not/ mandatory. Can you provide your /proc/mounts file contents Libvirt seems to be failing to detect the mount points 2013-0...

...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 the problem manifests itself.

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

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 Slackware's init system's scripts: /sys/fs/cgroup is mounted in /etc/rc.d/rc.S, the mai...

Hi all, This is a new release of blkio-cgroup v11. Changes: - The function cgroup_get_from_page() is added which determines to which cgroup a given page belongs. This function is introduced from Vivek's io-controller patch. Thanks Vivek. - Fix a type mismatch of the refcount of io_context. The refcount has been changed to atomic_long_t. This patch can be applied to 2.6.31-rc7. The
