Hi Bruce,

this mailing list is for the lxc-tools which are different from the 
libvirt-lxc which has implemented its own lxc driver.

I think you should ask at the libvirt@ mailing list. At the first 
glance, what you are describing is correct. It is the simpler way to 
create a system container. If you plan to run a lot of containers, there 
are some alternatives with btrfs or the ro-bind mounts to not duplicate 
the rootfs again and again.

Thanks
