linux9.0 vmware配置网卡不能起的bug：简单的说这是vmware虚拟网卡的bug，RH9包含检测网卡状态的脚本，但是在vmware下总是返回"link down"，解决方法如下： On Mandrake 9.1 add NO_MII_SUPPORT=yes to /etc/sysconfig/network-scripts/ifcfg-eth0.
On RedHat 9 add check_link_down() { return 1; } to the same file (just write it as is, Redhat fortunately allows functions in their config files...).
