Packstack Newton configuration with VLAN interface
I am trying to install a Packstack Newton in my LAB and I am having a big problem with the network because I don't understand how it should be configured the physical network.
So, I am using Packstack Newton, installed in Centos 7.3. I have 3 servers (1 controller with 2 computes) I am attaching a image to have a better understanding of the scenario.
The idea is that I can't figure out how the physical interface, that will be connected in the external bridge, should be configured.
All the interfaces for controller and computers are connected in a HP Switch that has the ports in trunk mode. I need to use VLAN 150. I have the interface em1 used for management and configured with VLAN in em1.150
The problems that I have is how to configure the physical interface em2: 1. Should I create em2.150 and add the VLAN and IP details and create the external network as a flat network? How should I have the answer file in this case? or 2.Should I let the interface unconfigured and create the external network from openstack as a VLAN network?
Thanks in advance, Razvan
