To create a new VNM driver, you need to create a new directory
inside /var/lib/one/remotes/vnm, and execute 'onehost sync' as oneadmin in
the front-end. OpenNebula will copy the new files to each Host in the next
monitorization cycle.

You have the complete VM xml information accesible trough the ruby class
VM, see src/vnm_mad/remotes/OpenNebulaNetwork.rb. The operator [] lets you
get the text value of any element using an expath expression.
The XML contents are documented in the xsd files that can be downloaded
from the api documentation [1].

The files src/vnm_mad/remotes/*.rb should provide you a base to start your
own driver.

Regards.
