#rmmod igb
#modprobe igb max_vfs=1 #系统自带驱动只支持一个参数，但每一端口均能生成VF

上intel下载igb最新的驱动，本实验采用了igb-2.4.13
#cd igb-2.4.13/src
#make
#make install
#lspci | grep Eth
#rmmod igb
#modprobe igb max_vfs=1,3 #新驱动支持对每一个端口设定不同的VF数目

配置IP，尝试ping其它机器，通则成功。
若虚拟机没有加载igbvf
在虚拟机安装igbvf后，重启虚拟机

***********系统运行环境******************************
需安装python-sqlalchemy、python-mysqldb
正常运行rails工程还需安装以下两个包，可能需要安装第3个包libapache2-mod-fcgid、libfcgi-ruby1.8
libapache2-mod-fcgid 1:2.2-1+lenny1 an alternative module compat with mod_fastcg
libfcgi-ruby1.8 0.8.7-4.1 FastCGI library for Ruby
libfcgi0ldbl 2.4.0-7 Shared library of FastCGI
