deletes flow table entries for other bridge as well

-------------------------------------
Summary: [OVS] Deleting one ovs bridge deletes flow table entries for other bridge as well
Key: CLOUDSTACK-6763
URL: https://issues.apache.org/jira/browse/CLOUDSTACK-6763
Project: CloudStack
Issue Type: Bug
Security Level: Public (Anyone can view this level - this is the default.)
Components: Management Server, Network Controller, XenServer
Affects Versions: 4.4.0
Environment: Latest build from 4.4 with commit d130530bd3e1cd6d8249d5045e00e4e4e2201521
Reporter: Sanjeev N
Assignee: Murali Reddy
Priority: Critical
Fix For: 4.4.0
[OVS] Deleting one ovs bridge deletes flow table entries for other bridge as well
Steps to Reproduce:
=================
1.Bring up CS in advanced zone with two hosts in a xen cluster
2.Create physical network with GRE isolation
3.Create network offering with connectivity service and OVS as the provider
4.Create a user account and deploy few vms with above network offering (make sure vms are spanned across the hosts)
5.Create another user account and repeat step4
6.Destroy all vms in account2
7.Verify flow table rules for the ovs bridge created for account1 network
Result:
=======
After deleting account2 vms ovs bridge for this network was destroyed from both the hosts and also the flow table rules for account1 network were also deleted from both the hosts
Observations:
===========
xapi3 is the bridge created for account2 network and xapi2 is for account1 network.
xapi3 is for network: OVSTunnel983
xapi2 is for network: OVSTunnel984
Following is the log snippet from MS log file for deleting OVS Bridge:
