Environment

System: Ubuntu 12.04 TLS
OpenVSwtich : v.20 openvswitch
Controller: Floodlight controller

#Install#

OpenVSwitch

按照文件中的INSTALL 即可安裝完成，

./configure (如果要安裝kernel module的話，./configure --with-linux=/lib/modules/uname -r/build 來建置)
make
make modules_install
/sbin/modprobe openvswitch
用 lsmod | grep openvswitch 檢查kernel module 是否載入
mkdir -p /usr/local/etc/openvswitch
ovsdb-tool create /usr/local/etc/openvswitch/conf.db vswitchd/vswitch.ovsschema (創造ovs-db)

ovsdb-server –remote=punix:/usr/local/var/run/openvswitch/db.sock \

--remote=db:Open_vSwitch,Open_vSwitch,manager_options \
--private-key=db:Open_vSwitch,SSL,private_key \
--certificate=db:Open_vSwitch,SSL,certificate \
--bootstrap-ca-cert=db:Open_vSwitch,SSL,ca_cert \
--pidfile --detach

ovs-vsctl –no-wait init
ovs-vswitchd –pidfile –detach

Network Environment

主機板網路孔*1 + 4 port 網卡
eth0 藉由internet與controller連接 (out-bound)
用ovs 創造一個虛擬的interface br0,把eth1, eth2, eth3, eth4加入 (in-bound)
eth1 & eth4 分別連上兩台host
host1: 192.168.122.100
host2: 192.168.122.101

Operation

ovs-vsctl add-br br0
ovs-vsctl add-port br0 eth1
ovs-vsctl add-port br0 eth2
ovs-vsctl add-port br0 eth3
ovs-vsctl add-port br0 eth4
ovs-vsctl set-controller br0 tcp:x.x.x.x:6633

Controller side

Switch 00:00:90:e2:ba:49:58:84 connected.
Watch x.x.x.x:8080/ui/index.html to see switch

Ovs side

ovs-vsctl show
