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
