Hi,
I have a topology like this;-
There are 3 Xen machines hosta, hostb, hostc with openvswitch installed in them.
Each of the machines has 3 VMs running in them.
In each Xen machine,
VMs are connected to bridge br0.
And there is a separate bridge br1 with a port em2.
In hosta's br0: There is a gre tunnel to hostb's br1.
In hostb's br0: There is a gre tunnel to hosta's br1 and to hostc's br1.
In hostc's br0: There is a gre tunnel to hostb's br1.
All the bridges are connected to a floodlight controller.
VM1 in 3 Xen machines is connected to port 7 of respective br0's.
Ping from VM1 in hosta to VM1 in hostb is succeeding and vice-versa.
Ping from VM1 in hostb to VM1 in hostc is succeeding and vice-versa.
But ping from VM1 in hosta to VM1 in hostc isn't succeeding though the route in
topology queried from floodlight is displaying the correct ingress, egress
traversals.
I see some errors in ovs-vswitchd.log
2012-12-30T00:22:49Z|49582|dpif|WARN|system@ovs-system: failed to flow_del (No

Can anyone please help me to figure out why VM1 in hosta isn't connecting to
VM1 in hostc?
I have attached ifconfig and floodlight route logs in the text file.
