Hi Simon, Please check you neuron server configuration. To support VXLAN networks, you should have the following configuration in the ml2_conf.ini:
[ml2] type_drivers = vxlan,local tenant_network_types = vxlan mechanism_drivers = openvswitch [ml2_type_vxlan] vni_ranges = 65537:69999 For the rest of the configuration, you can check the reference at http://www.opencloudblog.com/?p=300 Regards, Irena From: Xu (Simon) Chen [mailto:xche...@gmail.com] Sent: Thursday, October 02, 2014 6:47 PM To: openstack@lists.openstack.org Subject: [Openstack] [openstack][neutron] ml2 network creation question Hey folks, I was using vanilla openvswitch plugin and upgraded to ML2 recently. My existing networks work fine, but new networks are causing me troubles. It seems that a new network defaults provider:network_type to "local". Since I am running openvswitch agents with network_type set to VXLAN only everywhere, all ports are down in this setup. So, I tried to create a network and specify provider:network_type to vxlan (which is the case for my existing networks). This time, the network cannot be created at all, got an error of NoNetworkAvailable: Unable to create the network. Any ideas? Thanks. -Simon
