[one-users] Host-Based VLAN

[Hutson Betts]

I have a question regarding virtual networking by VLAN tagging using
OpenNebula's OCCI server.

Under the current OCCI implementation, and documentation, you specify
the bridge on which all vnets will be attached. This is accomplished by
configuring the following option:

# Configuration for OpenNebula's Virtual Networks
#:bridge: NAME_OF_DEFAULT_BRIDGE

This bridge is then associated with a physical network interface
manually, as seen in the bridge.png.

Unfortunately this configuration limits network isolation to isolation
enforced by ebtables.

I would like to leverage VLAN tagging to isolate virtual networks from
one another across my virtual machine hosts using OCCI as seen in
vlan.png.

There is an example given on the "Host-managed VLANs 3.0" configuration
page for managing VLAN tagging using VNET templates. In the given
example, you specify the physical network interface on which the VLAN
tagged virtual interface will be attached, and subsequently, the bridge
on which the vnet is attached.

However, there is no documentation containing instructions on how to
specify a physical network interface for OCCI.

How can OCCI be modified so that virtual machine created using the OCCI
interface as given virtual network interfaces attached to a physical
network interface?
