Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Set up RHOS 3 with Nicira plugin.
2. Launch some virtual machines and configure networking.
Quantum database queries get slow - like up to 1 min.
Quantum database queries should be sub-second.
Created attachment 791503 [details]
This backport has only been smoke-tested. It was modified a fair amount from the upstream backport.
We did some testing this afternoon. This patch introduces a bug where routers aren't deleted properly from the environment. Please do not use.
Ofer - could you please verify that the backporting did not cause any regressions, the scratch build to test is specify in comment #6.

Done - I've install the following packages on clean rhel 6.5 and then installed Grizzly/2013-11-14.2 ran my auto-test, all passed successfully:
Michael, we backported the fix and QE tested that there are no regressions.
We do not have access to setup with the required software (NVP/NSX plugin), who can verify the bug?
Adding >=POST to next async release
The patch with the backport and a scratch build was attached we did not get any feedback on the patch.
If we want this fix we need someone to verify it.
The customer found a temporary workaround by disabling the metadata service and believes the issue will go away when they move to Havana, and thus they closed the ticket.
