Unable to launch instances (Unexpected vif_type=binding failed)
Hi Community,
A lot many people have stopped by at the same error. I am trying to install openstack(3 node installation setup). When i try to create instances using the dashboard, i get a failure. Here is what i get in the nova-compute log.
==========================
Nova-compute.log

==========================
Have gone through all the similar questions on the forum, but unfortunately none of them have solved the issue for me. Have checked all the configuration files incessant number of times for any errors but to no avail. Some of these questions links that i went through are https://ask.openstack.org/en/question/57573/instance-failed-with-binding_failed-error-on-rhel7-openstack-icehouse/
Some of these answers are suggesting "Has created the tunnel in between Compute and Neutron and mapping the bridge communication" as the solution. But none of them have been kind enough to list the exact set of steps to do that.
Some of those answers have also suggested that deletion of the br-ex bridge and then manual creation will do. but when i try to delete the br-ex bridge . the bridge is not removed.
Can anyone suggest the set of steps that one need to do.
Thanking all of you lovely members in anticipation that the steps shall be suggested, or at least references to appropriate blogs on this issue will be given.
Forgot to tell the underlying OS is Centos 7 and have religiously followed the docs at http://docs.openstack.org/juno/instal... One more thing the compute and controller are not synced in time. Could that be an issue too?
