I have two servers, one running control and compute in the same node and another running just compute. Intention is to communicate between VM's running in different servers (in turn hypervisors) using tunnels. I am using Grizzly branch and i use devstack for installation. My localrc has ENABLE_TENANT_TUNNELS=TRUE in both control and compute.

When i run in the compute node, i get an error:

 [ERROR] ./ You are running OVS version 1.11.90. OVS 1.4+ is required for tunneling between multiple hosts.

In Folsom branch, i have seen the same error, and had the code as follows. But, in Grizzly, it's probably moved to some python library and i don't know where the code is:

The had the following comparison. Either the OVS versioning is not right (after 1.9, it should be 2.0?) or the comparison is wrong. Is that right? Then, is this a bug? Any workarounds?

     if [[ "$OVS_ENABLE_TUNNELING" = "True" ]]; then
         # Verify tunnels are supported
         # REVISIT - also check kernel module support for GRE and patch ports
         OVS_VERSION=`ovs-vsctl --version | head -n 1 | awk '{print $4;}'`
         if [ $OVS_VERSION \< "1.4" ] && ! is_service_enabled q-svc ; then
             echo "You are running OVS version $OVS_VERSION."

Thanks, KP

The code you mentioned still exists. It's in:

This looks like a bug to me. Please report it at which will get the developer's attention.

As a workaround in the meantime, you can consider editing lib/quantum_plugins/openvswitch directly in your devstack directory.
