Hi William,
>From the looks of it, you seem to be trying to use the Quantum LinuxBridge plugin and facing the issue. The error you mention below suggests that you might not be pointing to the right linuxnet_interface_driver (you should be seeing bridge names starting with a "brq-" and then first 11 characters of the network uuid, not the entire uuid). In the snippet of the nova.conf that you have below, I see that the option names for the drivers are spelt incorrectly as "*_drive" as opposed to "*_driver"; you should be having: libvirt_vif_driver=nova.virt.libvirt.vif.QuantumLinuxBridgeVIFDriver linuxnet_interface_driver=nova.network.linux_net.QuantumLinuxBridgeInter faceDriver Also, in case you are using devstack for your installation, you might want to look at the changes in this patch for getting the Quantum Linux Bridge plugin to work: https://review.openstack.org/#change,5667 Thanks, ~Sumit.
