Hello, I'm trying to configure small openstack infra (one network node, 2 compute nodes) with linux bridge and vxlan tenant networks. I don't know what I'm doing wrong but my instances have no connection between each other. On compute hosts I run neutron-plugin-linuxbrigde-agent with config like:
------------------ [ml2_type_vxlan] # (ListOpt) Comma-separated list of <vni_min>:<vni_max> tuples # enumerating # ranges of VXLAN VNI IDs that are available for tenant network # allocation. # vni_ranges = 10000:20000 # (StrOpt) Multicast group for the VXLAN interface. When configured, # will # enable sending all broadcast traffic to this multicast group. When # left # unconfigured, will disable multicast VXLAN mode. # # vxlan_group = # Example: vxlan_group = 239.1.1.1 [securitygroup] # Controls if neutron security group is enabled or not. # It should be false when you use nova security group. enable_security_group = True # Use ipset to speed-up the iptables security groups. Enabling ipset # support # requires that ipset is installed on L2 agent node. enable_ipset = True firewall_driver = neutron.agent.linux.iptables_firewall.IptablesFirewallDriver [ovs] local_ip = 10.1.0.4 [agent] tunnel_types = vxlan [linuxbridge] physical_interface_mappings = physnet1:eth1 [vxlan] local_ip = 10.1.0.4 l2_population = True enable_vxlan = True ------------------- Eth1 is my "tunnel network" which should be used for tunnels. When I spawn vms on compute 1 and 2 and after configuring network manually on both vms (dhcp is not working also because of broken tunnels probably) it not pings. Even when I started two instances on same host and they are both connected to one bridge: ------------------- root@compute-2:/usr/lib/python2.7/dist-packages/neutron# brctl show bridge name bridge id STP enabled interfaces brq8fe8a32f-e6 8000.ce544d0c0e5d no tap691a138a-6c tapbc1e5179-53 vxlan-10052 virbr0 8000.5254007611ab yes virbr0-nic ------------------- those 2 vms are not pinging each other :/ I don't have any expeirence with linux bridge in fact (For now I was always using ovs). Maybe someone of You will know what I should check or what I should configure wrong :/ Generally I was installing this openstack according to official openstack documentation but in this docs there is info about ovs+gre tunnels and that is what I changed. I'm using Ubuntu 14.04 and Openstack Kilo installed from cloud archive repo. -- Best regards / Pozdrawiam Sławek Kapłoński sla...@kaplonski.pl
