The Quantum network manager included with recent versions of OpenStack does not support the
--bridge-interface arguments to the
nova-list network create command. Short of writing a new Quantum plugin, is there any way to get Quantum to use existing bridge devices rather than creating new ones?
We are deploying OpenStack in an environment where we have a small number of VLANs assigned for use by our cloud environment. Our typical KVM host configuration exposes these via a number of bridge devices, and when manually bringing up new guest instances using
virt-install we simply assign them to the appropriate bridge device and we're good to go.
We haven't yet figure out how to integrate Quantum into this environment (or if it's even possible). As a fallback we can use some of the other networking support available in OpenStack, but we're having a hard time determining if our problems with Quantum are simply design decisions in the code or problems in our reading of the documentation.
