==============================
p4lang官网p4.org上的视频比较老，不能简单执行成功，下面是根据p4factory的guide安装过程，运行成功，仅供参考：
#虚拟机安装ubuntu1404版本，升级到最新
#克隆p4factory mast分支
git clone https://github.com/p4lang/p4factory.git
cd p4factory
git submodule update --init --recursive

# 用github 账号ssh clone应该不会看到以下问题

# 安装编译依赖工具，虚拟机内存要大于512M
./install_deps.sh
#如果中间thrift出错，手工进去sudo make install; sudo ldconfig 然后修改脚本，跳过这段继续执行
sudo tools/veth_setup.sh
# prepare workspace
./autogen.sh
./configure
# Run first sample:
cd targets/basic_routing/
make bm
sudo ./behavioral-model
# To test the sample
sudo python run_tests.py --test-dir tests/ptf-tests/
# To run Mininet
./run_demo.bash

# 新开窗口Add some entries， 这里应该看到前面窗口 ping成功
./run_add_demo_entries.bash

BMv2是新的switch模拟器，通过json文件动态加载生效，p4-factory这里的过程可以跑起来, 但是runtime_CLI.py调试工具跑不起来，请参照后面Behavioral-model文章。
Docker HUB上没看到现成image, TBD
