Kilo: compute node binding_failed
Hello,
I am currently configuring OpenStack Kilo on one machine as follows:
- host -> Compute Node
- VM on host -> Network Node
- VM on host -> Controller Node
After following all the instructions in the install guide (OpenSUSE13.2) I receive an error when starting up an instance.
In the compute node logs it indicates: NovaException: Unexpected vif_type=binding_failed.
As far as I have been able to determine, this error appears to be triggered by an empty or undefined bridge_mappings for the ml2 plugin. However, the install guide does not specify a bridge_mappings entry for the compute node so it is unclear to me if that is intentional or missing when using the GRE tunnel configuration.
When I put in: bridge_mappings = external:br-tun
the instance boots but I am not sure if this is correct.
Any guidance appreciated.
external network should be public network not bridge tunnel interface if you are using ovs ceheck the interface mapping aswell
