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.
