[lxc-users] Setting up unprivileged container in LVM

[Gordon]

I've been able to create and run an unprivileged container simply using 
the standard ext4 filesystem.

I'm trying to do the same thing inside a logical volume so the container 
is limited to that space. I know unprivileged users can't manipulate 
volumes, so I'm creating and mounting the logical volumes first, and 
then creating the container inside the directory. I'm getting the 
following when I try to create the container and am stumped. Not sure if 
it's a permission problem or what. I can create files by hand.

$ lxc-create -t download -n xxx -P /home/gmc/.local/share/lxc -- -d 
ubuntu -r trusty -a amd64
