I also have same problem when trying to get LXC running on Folsom.

Based on the following links:

http://docs.openstack.org/trunk/openstack-compute/admin/content/lxc.html
https://wiki.openstack.org/wiki/LXC
http://honeybutcher.de/2012/09/openstack-lxc/
http://docs.openstack.org/trunk/openstack-compute/admin/content/adding-images.html

I did the following things:

1. mkdir /cgroup
    set /etc/fstab with none /cgroup cgroup
cpuacct,memory,devices,cpu,freezer,blkio   0 0
    and reboot.
2. glance image-create --location
http://uec-images.ubuntu.com/releases/12.04/release/ubuntu-12.04-server-cloudimg-amd64-disk1.img
    --is-public true --disk-format raw --container-format bare --name "Ubuntu"
3. glance image-update [img-uuid] --property hypervisor_type=lxc

and still no luck.

I got the following error message from nova-compute node (I am not
quite sure whether there are other error msgs or not):
