Hi,Am trying to get a multi-node setup with Devstack having one controller and two compute nodes.Am able to get the vms on the controller node to ping each other, but vms on the compute node is not reachable. I have a single interface. Please let me know what am i missing here or if any different steps are required to get it working. local.conf on controller node is:[[local|localrc]]HOST_IP=10.21.18.30FLAT_INTERFACE=em1 LOGFILE=/opt/stack/logs/stack.sh.logADMIN_PASSWORD=adminMYSQL_PASSWORD=adminRABBIT_PASSWORD=adminSERVICE_PASSWORD=adminSERVICE_TOKEN=abcdefghijkl

Therefore, as before, no manual bridge creation is necessary to run openvswitch in single-node or multi-node configuration on systems that support OVS GRE tunneling. Regards,srindu
