[Openstack] Quantum with OVS and floating IP

[Razique Mahroua]

Hi guys,  I'm trying to setup Quantum on my lab (VM), the setup is quite simple, yet I can't have it working WAN (admin) <--->  eth0 LAN  <----> eth1 WAN  <----> eth2 Actually, I'm able to have the local connectivity working, VMs retrieve their private IP from quantum, yet the routing to the external network doesn't seem to work. When I add eth2 to the br-ex bridge, I lose connectivity to the VM (not the instance, but the openstack VM) root@ubuntu-precise:~# ovs-vsctl list-br br-eth1 br-ex br-int root@ubuntu-precise:~# ovs-vsctl list-ports br-eth1 eth1 phy-br-eth1 root@ubuntu-precise:~# ovs-vsctl list-ports br-ex    root@ubuntu-precise:~# ovs-vsctl list-ports br-int gw-82009a93-1a int-br-eth1 qvo5c1b075c-58 tapee397b47-c9 /etc/quantum/plugins/openvswitch/ovs_quantum_plugin.ini root@ubuntu-precise:~# cat /etc/quantum/plugins/openvswitch/ovs_quantum_plugin.ini | grep -v -e "#" -e "^$" [DATABASE] sql_connection = mysql://ovs_quantum:openstack@10.211.55.20/ovs_quantum reconnect_interval = 2 [OVS] tenant_network_type = vlan network_vlan_ranges = physnet1:1:4094 tunnel_id_ranges = 1:1000 integration_bridge = br-int local_ip = 10.211.55.20 bridge_mappings = physnet1:br-eth1 [AGENT] polling_interval = 2 root_helper = sudo /usr/bin/quantum-rootwrap /etc/quantum/rootwrap.conf The quantum-settings-partay http://paste.openstack.org/show/22356/ Best regards, Razique Nuage & Co - Razique Mahroua  razique.mahr...@gmail.com
