Open Stack

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?


Thanks,
