Comment 1 for bug 1514227

My view about developer deployment of kolla on single NIC is that it should not be recommended. Specially when someone is trying to deploy directly on their laptop. Here are the reasons

1) You need a physical connection to the network as wifi cannot be used.
2) You need to have a static IP address of machine, which is really difficult if it is a laptop
3) As you move from one network to another your setup is not going to work
4) At times you may end up messing up with your machine network and hence it may not work at all
5) We are complicating the already complicated networking by creating bridges, veth-pair which would make it difficult to debug some of the issues/problems.

Instead of deploying kolla direcltly on a baremetal with a single NIC, the user should do the same on VM. The advantages are as follows

1) No need for physical connection to the network as wifi can be used
2) No need of static ip address for the host machine
3) The setup is network agnostic and hence will work on any networks
4) No impact on physical machine instead it just impacts the VM which can always be deleted/restored from a backup copy.
5) In a VM you can clearly define the network interfaces and hence it makes easier to understand an debug issues,

So in my opinion the documentation section for baremetal with single NIC should advice the user to use a VM instead of baremetal deployment.
