Creating a new Network for a dual NIC VM

I need a second network for testing a packstack deployment. Here is what I did to create it, and then to boot a new VM connected to both networks.

Once again the tables are too big for the stylesheet I am using, but I don’t want to modify the output. The view source icon gives a more readable view.

The Common client supports creating networks.

But not any of the other neutron operations…at least not at first glance. we’ll see later if that is the case, but for now, use the neutron client, which seems to support the V3 Keystone API for Auth. Create a subnet:

The router needs an interface on the subnet.

Not sure if I need to create a port, but worth testing out;
