Hi list, i have a nearly working neutron + openvswitch + VLAN setup but, i have a small problem however...
I am running neutron-server on a node controller and neutron-openvswitch-agent and neutron-dhcp-agent running on a compute node. On the compute node, i have an initial bridge, with two physical interfaces in bonding, with some VLANs trunked on the bond. On the controller node, i created a network with --provider:network_type vlan and --provider:segmentation_id xxx (xxx being one of the VLAN trunked on the bond inside my initial bridge). Then, i created a subnet on that network. When i launch neutron-dhcp-agent on the compute node, everything seem fine : the namespace is being created, there is a port with tag 1 on the integration bridge for the dnsmasq process and, i can ping the IP of the dnsmasq process from a device on the xxx vlan. I can also see the openflow flows for vlan modification on both bridge (vlan xxx to vlan 1, vlan 1 to vlan xxx). However, my problem is that when i launch a VM using the network i created in neutron, a port is being created in the integration bridge but, it is not tagged with vlan 1 so, the VM is unable to communicate on the network. As soon as i tag the port with vlan 1, with a command like : ovs-vsctl set Port tap1234-ab tag=1 the VM is able to communicate on the network. So, am i missing something obvious? Or maybe that i have something misconfigured in my neutron setup? Any help would be greatly appreciated.
