This means we'll need to modify the LXC XML so that it creates a 
filesystem device.  We could do something like:

         <filesystem type='mount'>
             <source dir='/tmp/lxc_files'/>
             <target dir='/tmp/'/>
         </filesystem>


/tmp/lxc_files is a directory we'll need to create in order to define / 
create a container.  For testing purposes, we aren't concerned with 
contents of /tmp/lxc_files.  However, a customer would create such a 
directory for storing config files / executables / etc that the 
container would need to access during runtime.

We'll also need to do something similar for DefineSystem() case as well.
