fog--fog/lib/fog/libvirt/compute.rb
Patrick Debois 4740174f12 [Libvirt] renamed 'raw' connection to raw in the Fog Connection
Because the initial provider was copied from the virtualbox example we ended up with a notation
connection.connection for the raw provider

The function of the raw are injected on the connection object. Still in analogy with the raw
for server , volume, ... it makes sense to rename connection.connection to connection.raw

Also all calls to the raw connection are now explicit
