I just installed openstack with one controller and one compute node following the documentation in the web. I can start instances, but they aren't getting the ip in openstack

I'm having this message in the logs: "Could not load neutron.agent.linux.interface.BridgeInterfaceDriver"

When I launch an instance, I got this:

| c4b2e251-b542-482c-b872-5fb93f1a8045 | provider-instance3 | ACTIVE | provider= | cirros |

but that ip addres is not present in any interface/bridge of my compute/controller node and I can't reach the instance

Some output here:

openstack network list

| 21e175bd-d49f-49a6-b510-c909b3c0e90e | provider | c8971772-4951-4bd3-8dea-40b9f5c08ce5 |

openstack network agent list

| 273e90d9-20fc-465f- | Metadata agent | controller | None| True | UP | neutron-metadata-agent |

| 815008db-f031-489a- | Linux bridge agent | controller | None| True | UP | neutron-linuxbridge-agent |

| d3b5b172-b323-4fc5- | Linux bridge agent | compute1 | None| True | UP | neutron-linuxbridge-agent |

| ee2a777d-db8d-4cfd- | DHCP agent | controller | nova | True | UP | neutron-dhcp-agent |

Any idea? Thanks

If the message is not marked as ERROR, you can probably ignore it. See also In this case, unreachable instances or other problems are caused by something else.

From the original question: "that ip addres is not present in any interface/bridge of my compute/controller node". That's normal, since the IP address belongs to the instance and not an interface on the controller or compute nodes.

Hi, Having the same issue. The file ./usr/lib/python2.7/site-packages/neutron/agent/linux/ contains class BridgeInterfaceDriver(LinuxInterfaceDriver): """Driver for creating bridge interfaces.""" For me both mechanism and extension drivers are not loading
