[Rdo-list] Packstack, Neutron, and Openvswitch

[Dan Mossor]

Howdy folks!

I am still trying to get an Openstack deployment working using 
packstack. I've done a lot of reading, but apparently not quite enough 
since I can't seem to get my compute nodes to talk to the network. Any 
pointers anyone can give would be *greatly* appreciated.

Here's the setup:
Controller - 1 NIC, enp0s25
Compute Node node3: 3 NICs. enp0s25 mgmt, enp1s0 and enp3s0 slaved to bond0
Compute Node node4: 3 NICs. enp0s25 mgmt, enp1s0 and enp2s0 slaved to bond0

I wanted to deploy the neutron services to the compute nodes to take 
advantage of the bonded interfaces. The trouble is, I don't think I have 
my answer file [1] set up properly yet.

After the packstack deployment, this is what I have on node3 (I'm going 
to concentrate solely on this system, as the only difference in node4 is 
one of the physical interface names).

     ovs_version: "2.1.3"


The trouble lies in the fact that I have NO IDEA how to use 
openvirtualswitch. None. This ovs-vsctl output is foreign to me, and 
makes no sense.

At the very least, I'm simply looking for a good reference - so far, 
I've not been able to find decent documentation. Does it exist?

Thanks,
Dan
