I've seen a number of questions around issues with Icehouse producing NovaException: Unexpected vif_type=binding_failed. There have been a number of suggestions none of which worked for me so hoping someone can tell me what I'm missing here. I'm running a 4 node configuration controller, network, compute & block storage.

Nova-compute.log extract from compute node

What are the suggestions of which none worked for you? If you can tell us what you've looked at we can avoid suggesting things you've already tried.

Sorry good point. 1. (checked conf file included fixes) 2. (added suggested libvirt_vif_driver=nova.virt.libvirt.vif.LibvirtGenericVIFDriver to nova.conf on compute node)

  1. Tried the suggestion: without success. Found both options are valid dependent on section see:

Most likely your bridges need to be recreated on your compute nodes. I ran into exact same issue after running "yum update" on two of my compute nodes, and started getting same error on both nodes.

I end up running the following commands to get it back...

ovs-vsctl del-br br-int
ovs-vsctl add-br br-int

I recommend a reboot after running these commands.

Thanks Yellow circle. I tried your suggestion same issue but I do get a new info/error mesg from neutron api in the nova log " INFO - Unable to reset device ID for port None" so progress. There wasn't a corresponding error/info mesg in openvswitch-agent.log.

The bridge was definitely the cause of the issue. It took a reinstall to get it running.

I tried to do the same what you mentioned above , but that bridge is not deleted or i also tried to delete port inside that br but not successful .

I am also unable to delete that br-int bridge using "ovs-vsctl del-br br-int". Any suggestions as to how did you resolve this issue
