打开Makefile,发现

INCLUDE         = -I/usr/src/linux/include -I.. -I.

需要做个软连接。

进入/usr/src目录

[vagrant@localhost src]$ pwd

/usr/src

[vagrant@localhost src]$ ll

total 20

drwxr-xr-x 2 root root 4096 Jan 26  2010 debug

lrwxrwxrwx 1 root root   49 Nov 21  2012 vboxguest-4.2.0 -> /opt/VBoxGuestAdditions-4.2.0/src/vboxguest-4.2.0

ln -s生成一个软连接。

[vagrant@localhost src]$ sudo ln -s /usr/src/kernels/2.6.18-238.el5-x86_64/ /usr/src/linux

再进行编译安装ipvsadm就成功了。
