Hello. I followed the installation guide for OpenStack Icehouse, and the installation was completed successfully; Two Instances could ping with each other through GRE tunnel.
After that, I've tried to modify the Networking from GRE to VXLAN by following the Configuration Reference described http://docs.openstack.org/trunk/config-reference/content/networking-plugin-ml2_vxlan.html Although I modified all the parameters like "type_drivers", "tenant_network_types", "vni_ranges", etc. and restart all the related services on the every nodes, the VXLAN network doesn't work fine at all. First, I could not add an additional network on dashboard. Second, the br-tun on both Compute Node and Network Node did not have a port for VXLAN. I read the configuration guide at http://kimizhang.wordpress.com/2014/04/01/how-ml2vxlan-works/, and the guide describes /etc/neutron/plugins/openvswitch/ovs-neutron_plugin.ini also needs to be modified. But I didn't because the Installation Guide for OpenStack Icehouse didn't mention such things even though the guides shows how to set up the GRE as default. Should I modify /etc/neutron/plugins/openvswitch/ovs-neutron_plugin.ini? Or what I need to do? Best regards Byeong-Gi KIM
