Hi Kevin I'm trying the below link for the same functionality....
http://linuxmantra.com/2013/08/gre-tunneling-with-open-vswitch.html I'm able to reach tep0 of Hypervisor1 from both the VMs but I wonder why I'm not able to reach tep0 of Hypervisor2 from VM1 and VM2. Could you help regarding this? It will be great if you share your set-up configuration with me so that We both may be able to look onto this. Thanks.. Sonia...
