Description Aswin Suryanarayanan 2017-07-26 11:04:42 UTC
Description of problem:
Traffic between Two VM having FIP is not working if the VM are in the same compute node when Openstack is installed with Opendaylight as the network controller.

The packet is dropped by security groups which is implemented using ovs-conntrack. The netfilter fails to receive some of the packets submitted from the pipeline and marks it as invalid.

Version-Release number of selected component (if applicable):


How reproducible:
A Openstack setup with opendaylight is required.
Steps to Reproduce:
1.Spawn two VM in the same compute node. 
2.Assosiate  FIP both the vms
3.SSH from vm1 to vm2 using the FIP

Actual results:
SSH should succeed.

Expected results:
SSH is failing

Additional info: Thread regarding the issue ovs-discuss[1]. A similar issue is observed in Ovn controller as well.

This bug is for tracking an immediate fix for OpenDaylight/NetVirt. BZ 1464061 is still there to track the long-term fix in Open vSwitch.
