Thread-topic: [nova-network] question about nova-network
User-agent: Microsoft-MacOutlook/14.2.4.120824
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.
