Searching for a valid kernel header path... The path "" is not a valid path to the ***** kernel headers. Would you like to change it? [yes]

在centos 6.5安装vmtools时候，解压包，mount挂载后，安装pl过程中报 这个问题，半天没有解决，google 后发现这样就行了

I installed the kernel-devel package, but it turns out that the headers were for a different kernel version than the one that was running on my instance. In order to fix the problem, I ran

sudo yum upgrade

and rebooted, and then vmware-tools installed without a fuss.

输入 sudo yum upgrade ,之后重启，再次重新安装解决。

如果此时没有出现全屏，则将虚拟机的【View】->【Autosize】->【Autofit Guest】,【Autofit Window】都选上。即可实现全屏。

另外：如果上不去网，直接用：dhclient -v
