Hi yong,
It seems you didn't mount all of the 'cpuacct', 'devices' & 'memory' cgroups.
You can see If you missed mounting one of them in the cgroup dir
"/sys/fs/cgroup" or execute command "mount" to see which cgroup you mounted.
Thanks

hello
I have a problem when trying to get LXC running on CentOS6.4 + OpenStack
Grizzly .
I did flowing things
1. Change nova.conf ,"libvirt_type=lxc"
2.compile nbd and qemu-nbd
3.create image and update" --property hypervisor_type=lxc"
4."mount none -t cgroup -o cpuacct,memory,devices,cpu,freezer,blkio
/cgroup",based on https://wiki.openstack.org/wiki/LXC
When I launch instance,something still wrong.I got the following error message
from nova-compute node (I am not quite sure whether there are other error msgs
or not):

but I do mount subsys on /cgroup.Has anybody seen the same problem and any
solution?
