[RFE] Add per-node network-to-NIC mapping

[Dan Sneddon]

In order to test spine/leaf, we need to be able to configure nodes so that they appear to be on different networks. This can be achieved by creating multiple networks and attaching the virt-host to each bridge and performing routing between networks on the virt host.

The problem is that when multiple networks are created, each node gets the same network/NIC mapping. So each node has NIC1 attached to the provisioning network. Since spine/leaf will have multiple provisioning networks with routing between them, we need to be able to configure some nodes to have NIC1 on network 1 and others to have NIC1 on network 2 or 3, etc.

This could be achieved with a map of network-to-NIC on a per-node basis.

Is this still needed?

[Harald Jensås (harald-jensas)]

How are planning to test edge cases such as Distributed Compute, as well as the Spine-Leaf usecase without it?

NOTE: We do have support in OVB to set up a lab with routed networks now, so it's less urgent. Still I think it makes sense to keep this around as a wishlist item?
