In a fresh raring instance I mounted a btrfs disk on /mnt, and did
lxc-create -t ubuntu -B btrfs -P /mnt -n c1
for i in `seq 1 10`; do
lxc-clone -s -p /mnt -o c1 -n x$i
done
for i in `seq 1 10`; do
lxc-start -d -P /mnt -n x$i
done
Then connected to two of the containers with lxc-console,
lxc-console -P /mnt -n x2
lxc-console -P /mnt -n x9
both were up and had unique ip addresses.
Again this was a raring instance with ppa:ubuntu-lxc/daily installed.
