rhel 6使用lxc报错 ：no ns_cgroup option specified

That's a known problem.  You don't have to remove them, merely disable

them, by running "chkconfig cgconfig off" and "ckconfig cgred off" and

rebooting.  Then mount your cgroup on a common mount point.  I get the

impression from Serge and Daniel that this problem can't be solved with

that kernel because that kernel doesn't support clone_children so you

don't have any recourse.

This sounds like my "failed" case in testing with libcgroup enabled.



The fact that it's mounted on /cgroup and not /sys/fs/cgroup does not

bode well all all.



1) uname -a



2) chkconfig cgconfig



You probably need to add a line to your /etc/fstab long the lines of

this:



cgroup  /sys/fs/cgroup    cgroup  defaults        0 0



Then run the commands:



chkconfig cgconfig off

chkconfig cgred off



The reboot (I have NOT had luck manually unmounting those cgroups and

remounting as a single mount point).



If I understand Serge's comments correctly, we can not get the

multipoint mounts to work even with the patched and updated lxc package

due to the lack of "clone_children" in that kernel, so you need to

switch a single mount-point mount to get lxc to work.  Then you don't

even need the multipoint patches to get it to work though you may have

tweaks to make.
