Answer by darragh-oreilly for HI, I am trying to configure Juno Openstack with VLAN settings in ubuntu 14.04. Setup has an issue with VMs getting IP from DHCP agent. While troubleshooting, I have found the following errors in openvswitch.log file. Attached is the snapshot of the error log. Kindly help me with solutions. openVswitch-error-log-file [ml2] # (ListOpt) List of network type driver entrypoints to be loaded from # the neutron.ml2.type_drivers namespace. # # type_drivers = local,flat,vlan,gre,vxlan tenant_network_types = vlan type_drivers = vlan mechanism_drivers = openvswitch,brocade # Example: type_drivers = flat,vlan,gre,vxlan # (ListOpt) Ordered list of network_types to allocate as tenant # networks.
