[one-users] combining network drivers

[Jaime Melis]

Hi Alexandre,

Basically what you need to know is that every network driver has three
scripts: pre/post/clean. You can call any functionality whatsoever from
within those scripts.

In particular I recommend you reuse the 802.1q driver, if you take a look
here [1]

pre: during the pre stage the HostManaged (OpenNebulaHM) driver is called,
which creates the bridge and the vlan tagged physical interface
post: at this stage the firewall drivers are called

You can of course add any extra calls in those scripts.

Alternatively, you can add add a new set of drivers (cp
-r /var/lib/one/remotes/vnm/802.1Q/ /var/lib/one/remotes/vnm/802.1Q_route)
and edit those. Remember that your host needs to have 802.1Q_route as the
VNM driver (delete the host and recreate it).
