If you look at the LXC_DiskResourceAllocationSettingData class in the
ResourceAllocationSettingData.mof file, you'll see an additional field
called "MountPoint" which is the target within the container. The
"Address" field specifies the source as on the other platforms.
However, the source for a container is a path on the filesystem, not a
device or an image file.
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.
