在CentOS-6.9里安装openvswitch-2.5.4

第一步：安装依赖

yum install rpm-build openssl-devel gcc wget
yum install python-devel kernel-devel kernel-debug-devel libtool

第二步：下载包
wget -O /root/rpmbuild/SOURCES/openvswitch-2.5.4.tar.gz http://openvswitch.org/releases/openvswitch-2.5.4.tar.gz

第三步：解压并配置spec文件
cd /root/rpmbuild/SOURCES/
tar zxvf openvswitch-2.5.4.tar.gz
sed 's/openvswitch-kmod, //g' /root/rpmbuild/SOURCES/openvswitch-2.5.4/rhel/openvswitch.spec > /root/rpmbuild/SOURCES/openvswitch-2.5.4/rhel/openvswitch_no_kmod.spec

第四步：生成RPM
rpmbuild -bb --without check /root/rpmbuild/SOURCES/openvswitch-2.5.4/rhel/openvswitch_no_kmod.spec
error: Bad exit status from /var/tmp/rpm-tmp.hjPLog (%install)
编译失败

下面参考阿里云用1.9.3版本
https://yq.aliyun.com/articles/18204

wget -O ~/rpmbuild/SOURCES/openvswitch-1.9..tar.gz http://openvswitch.org/releases/openvswitch-1.9.3.tar.gz
cd ~/rpmbuild/SOURCES/
tar -zxvf openvswitch-1.9..tar.gz

cd ~/rpmbuild/SOURCES/openvswitch-1.9.
rpmbuild -bb rhel/openvswitch.spec

cd ~/rpmbuild/RPMS/x86_64/
rpm -ivh openvswitch-1.9.-.x86_64.rpm

chkconfig --list|grep openvswitch
service openvswitch start

卸载原来的
rpm -e openvswitch-1.9.3-1

开始下载新版本v1.11.0

wget -O ~/rpmbuild/SOURCES/openvswitch-1.11..tar.gz http://openvswitch.org/releases/openvswitch-1.11.0.tar.gz
cd ~/rpmbuild/SOURCES/
tar -zxvf openvswitch-1.11..tar.gz

cd ~/rpmbuild/SOURCES/openvswitch-1.11.
rpmbuild -bb rhel/openvswitch.spec

cd ~/rpmbuild/RPMS/x86_64/
rpm -ivh openvswitch-1.11.-.x86_64.rpm

chkconfig --list|grep openvswitch
service openvswitch start

OVS管理维护

1：查看版本及配置
ovs-vsctl show

2：添加一个虚拟交换机
ovs-vsctl add-br br0

3：把物理网口加入到虚拟交换机
ovs-vsctl add-port br0 eth0

4：删除虚拟交换机
ovs-vsctl del-br br0

修改KVM虚拟机配置
virsh edit vm12

把原来的
<interface type='network'>
  <source network='default'/>
  <model type='virtio'/>
</interface>

改成
<interface type='bridge'>
  <source bridge='br-usb0'/>
  <virtualport type='openvswitch'>
  </virtualport>
  <model type='virtio'/>
</interface>
