External issue ID:

7606

Description

Steps:

Create a network
Create a VM in Compute_1 node
Perform live-migration
nova live-migration <VM_ID> <Compute_2 node>
Ping operation between DHCP and VM
ip netns exec qdhcp-<network_ID> ping -c <VM_IP_ADDRESS>

Observation:

Before live-migration, the ping operation between DHCP and VM was successful.
After VM migrated from Compute_1 node Compute_2 node, the ping fails.
Once the migration happened in new compute node (Compute_2) the tunnel flow for the VM is missing.
Multiple flow entries for the same VM in table:110
Before_migration/ovs_comp2.log -> 2 similar entries in table:110 for DHCP Agent.One with additional match attribute on priority and the other without.
Before_migration/ovs_ctrl.log -> 2 entries for the VM one with priority and the other without.
