Priority: Critical
Fix For: 4.4.0
[SDN] OVS bridge/tunnel ports are not getting deleted from Host even though
there are no vms in the network
Steps to Reproduce:
================
1.Bring up CS in advanced zone with two hosts in a cluster
2.Create physical network with GRE isolation
3.Create network with Connectivity service and OVS as the provider
4.Deploy couple of vms in the above network.
5.Migrate vms to one host and make sure that all the vms (including vr) are
running only on one host
6.Verify tunnel ports on the host where there are no vms running
Expected Result:
==============
Tunnel ports and ovs bridge shall be deleted from the host where no vms are
running
Actual result:
===========
OVS bridge and tunnel ports are still present even after migrating all the vms
to another host in the cluster
Observations:
============
Following bridge info is from the host on with all system vms and guest vms are
running
[root@xen-host-13 ~]# ovs-vsctl list-br
xapi0
xapi1
xapi2
xenbr0
xenbr1
On the host where only guest vms are running
[root@xen-host-14 ~]# ovs-vsctl list-br
xapi2
xenbr0
xenbr1
Before migration:
==============
[root@xen-host-13 ~]# ovs-vsctl list-ports xapi2
t997-1-2
vif12.0
vif13.0
[root@xen-host-14 ~]# ovs-vsctl list-ports xapi2
t997-2-1
vif7.0
After migration:
=============
[root@xen-host-13 ~]# ovs-vsctl list-ports xapi2
t997-1-2
vif12.0
vif13.0
vif15.0
[root@xen-host-13 ~]#
Following is the target host on which no vms are running:
[root@xen-host-14 ~]# ovs-vsctl list-br
xapi2
xenbr0
xenbr1
[root@xen-host-14 ~]# ovs-vsctl list-ports xapi2
t997-2-1
