ovn编译

 编译参考：https://github.com/ovn-org/ovn/blob/master/Documentation/intro/install/general.rst

 git clone http://github.com/openvswitch/ovs.git

yum -y install python3
 pip3 install six

[root@kunpeng82 ovs]# ls ~/rpmbuild/

./boot.sh

./configure --with-ovs-source=../rpmbuild/SOURCES/openvswitch-2.12.0/ --with-ovs-build=../rpmbuild/BUILD/openvswitch-2.12.0/   

   make

报undefined reference to `ovs_cmdl_env_parse_all'

1、 重新下载一个openvswitch-2.13.0

2、先编译openvswitch-2.13.0

3、./configure --with-ovs-source=../ovs  --with-ovs-build=../ovs

4、make -j 96  编译 ovn

5、make install
