Hi, I'm sorry, I missed reading the end of your post.
Using GRE tunnels inside VMs with OVS firewall driver. If GRE tunnels from VM to VM are going to be used, the native OVS firewall implementation requires nf_conntrack_proto_gre module to be loaded in the kernel on nodes running the Open vSwitch agent. It can be loaded with the command: # modprobe nf_conntrack_proto_gre Some Linux distributions have files that can be used to automatically load kernel modules at boot time, for example, /etc/modules. Check with your distribution for further information. This isn’t necessary to use gre tunnel network type Neutron. If you didn't load nf_conntrack_proto_gre, you'll need to load it. Then you can ping.
