Booting an instance with multiple fixed addresses
Multiple external networks with a single L3 agent
In the old days (so, like, last year), Neutron supported a single external network per L3 agent. You would run something like this...
$ neutron net-create external --router:external=true
...and neutron would map this to the bridge defined in
/etc/neutron/l3_agent.ini. If you
wanted to support …
Video: Configuring OpenStack's external bridge on a single-interface system
I've just put a video on Youtube that looks at the steps required to
set up the external bridge (
br-ex) on a single-interface system:
Open vSwitch and persistent MAC addresses
Normally I like to post solutions, but today's post is about a vexing problem to which I have not been able to find a solution.
This started as a simple attempt to set up external connectivity on
an all-in-one Icehouse install deployed on an OpenStack instance. I
wanted to add
br-ex in order to model a typical method for
providing external connectivity, but I ran into a very odd problem:
the system would boot and work fine for a few seconds, but would then
promptly lose network connectivity.
