<p>A flat network for LB management should work as well. However,
the LB management network has nothing to do with your VMs (except
the amphorae), and it's unclear to me what ports you are adding to
them and the Neutron router. There is no router for a flat
network. <br>
</p>
<p>You seem to imply that your machines (controllers, computes) are
virtual. My experience with Kolla is also in a virtual
environment. I had to abandon VLAN or flat LB management networks
because I was not competent enough to solve the networking
problems outside of Kolla and went for the tenant network solution
that I shared. <br>

<p class="MsoNormal">Thank you! I am trying the path of adding
a separate physical (although its really virtual..) network
that will be exclusively for lb-mgmt….that would work also,
correct? I added a port to my virtual router and the added a
corresponding port to each openstack vm. It sounds like only
control and compute nodes need it but I was going to add it to
everything to start and then eliminate one by one once it
worked.

<p class="MsoNormal">The stacktrace shows that Octavia can't
reach an Amphora. I suppose you get this log when trying to
create a loadbalancer? If so, most likely the Amphora
management network is not set up correctly.
<o:p></o:p></p>
<p>The difficulty is that Octavia workers, which are <i>processes
</i>running on the controllers, need to have access to the
same management network as the Amphora
<i>instances</i>. If you implement the management network as a
normal tenant network, some non-trivial manual Openvswitch
configuration is required. See

moz-do-not-send="true">
https://docs.openstack.org/octavia/latest/install/install-ubuntu.html#install-and-configure-components</a>
for instructions. In production settings, usually a VLAN is
used, which is easy to access from controller processes.<o:p></o:p></p>
<p>I succeeded running Octavia on a Kolla cluster with three-way
controllers, with a tenant network (VXLAN-based) for amphora
management. My notes are attached (they are tailored to my
configuration, of course).<o:p></o:p></p>

<p>Well…it gets. A lot further…. I see this error now…. Im
looking around to see if it’s a security group missing or if
there is some other setting I missed. Im not seeing any
scripts to prep the env…usually there is something like that
if it’s a security group…anyone know?<o:p></o:p></p>
