安装 Quantum openvswitch agent, l3 agent 和 dhcp agent:

service quantum-plugin-openvswitch-agent restart service quantum-dhcp-agent restart service quantum-l3-agent restart service quantum-metadata-agent restart 计算节点 网络设置 cat /etc/network/interfaces auto eth0 iface eth0 inet static address 172.16.0.53 netmask 255.255.0.0 auto eth1 iface eth1 inet static address 10.10.10.53 netmask 255.255.255.0* 因为没有内网 apt 源，所以临时设置个虚拟网卡来 apt-get：
ifconfig eth0:0 192.168.8.53/24 up route add default gw 192.168.8.1 dev eth0:0 echo 'nameserver 8.8.8.8' >> /etc/resolv.conf 添加源添加 Grizzly 源，并升级系统:
echo 'deb Ubuntu-cloud.archive.canonical.com/ubuntu precise-updates/grizzly main' > /etc/apt/sources.list.d/grizzly.list apt-get update apt-get upgrade apt-get install ubuntu-cloud-keyring设置 ntp 和开启路由转发:
# apt-get install ntp # sed -i 's/server ntp.ubuntu.com/server 172.16.0.51/g' /etc/ntp.conf # service ntp restart # vim /etc/sysctl.conf net.ipv4.ip_forward=1 # sysctl -p OpenVSwitch安装 openVSwitch:
apt-get install openvswitch-switch openvswitch-brcompat设置 ovs-brcompatd 启动：
sed -i 's/# BRCOMPAT=no/BRCOMPAT=yes/g' /etc/default/openvswitch-switch echo 'brcompat' >> /etc/module启动 openvswitch-switch:
/etc/init.d/openvswitch-switch restart * ovs-brcompatd is not running # brcompatd 没有启动,尝试再次启动. * ovs-vswitchd is not running * ovsdb-server is not running * Inserting openvswitch module * /etc/openvswitch/conf.db does not exist * Creating empty database /etc/openvswitch/conf.db * Starting ovsdb-server * Configuring Open vSwitch system IDs * Starting ovs-vswitchd * Enabling gre with iptables再次启动,直到 ovs-brcompatd、ovs-vswitchd、ovsdb-server等服务都启动：
# /etc/init.d/openvswitch-switch restart # lsmod | grep brcompat brcompat 13512 0 openvswitch 84038 7 brcompat如果还是启动不了 brcompat，执行下面命令：
/etc/init.d/openvswitch-switch force-reload-kmod创建 br-int 网桥:
ovs-vsctl add-br br-int
