This includes<br> the LibvirtBridgeDriver, and the LibvirtHybridOVSBridgeDriver (which<br> devstack now defaults to for Quantum with OVS plugin). This is<br> being tracked here: <a href="https://bugs.launchpad.net/nova/+bug/1050433" data-mce-href="https://bugs.launchpad.net/nova/+bug/1050433">https://bugs.launchpad.net/nova/+bug/1050433</a> . I<br> suspect the fix could be just a simple if-check, and could probably be<br> included in a later stable release. This bug hasn't really been a<br> priority, as the main reason for using the<br> LibvirtHybridOVSBridgeDriver is to work with nova security groups, and<br> using the NoopFirewallDriver disables
