Hi Darren,
I have moved along a bit, but now running a different issue related to
launching a VM. The latest issue is related to an "RPC message timeout" in
nova-network. If you have a few minutes, would really appreciate your help.
I have a two node setup:
- controller-node (hostname: bodega. running nov-* services, including
nova-network, but no nova-compute)
- compute-node (hostname: sonoma, running nova-compute)
Two issues:
- I see the controller-node, nova-network sending a message to sonoma which is
timing out. Did I not setup a consumer of the message on the compute-node
properly? I am guessing rabbitmq-server is dropping the message on the floor
(but no log entry about dropped message, probably need to configure some log
config).
- Why is nova-nework assigning an floating IP to the VM instance?

Subject: Re: [Openstack] [nova-network] question about nova-network
Ahmed,
Are you still having issues here? What error are you actually getting when
trying to spin up the vm? The API log shows no errors, but it's likely the
compute.log from the compute node is where the errors show up.

Hello,
I have two physical servers, one server configured as as the controller node
(running all nova services, except nova-compute), and second server as a
compute node (running nova-compute). My question is how does the controller
node know there is a compute node "out there", and that all Vms should be
instantiated on it?
Also, my understanding is when the first VM is instantiated, the bridge
interface "br100" will be created automatically by nova-network on the
controller node. I am assuming user has to manually create the "br100" on the
compute node(s). Is that right?
The reason I ask is I am trying to instantiate a VM, but running into an error.
