How to install User_Mode_linux?

I tried to install and run it, but get the following error message:

user_mode_linux-2.4.12.1um-0.i386.html
The user-mode port of the Linux kernel
SourceForge
user_mode_linux-2.4.12.1um-0.i386.rpm


看了这篇文章不懂的地方还真多
user_mode_linux是做什么的
查了一下解释是The user-mode port of the Linux kernel
但是又发现他的distribution是SourceForge

这个是什么系统，一起没有听说过

看了下面一段，明白了许多。
其实就是一个虚拟机，也就是一个linux子系统运行在user mode，
可以用来测试软件和内核而不影响到主系统。

http://user-mode-linux.sourceforge.net/
User-Mode Linux is a safe, secure way of running Linux versions and Linux processes. Run buggy software, experiment with new Linux kernels or distributions, and poke around in the internals of Linux, all without risking your main Linux setup.
User-Mode Linux gives you a virtual machine that may have more hardware and software virtual resources than your actual, physical computer. Disk storage for the virtual machine is entirely contained inside a single file on your physical machine. You can assign your virtual machine only the hardware access you want it to have. With properly limited access, nothing you do on the virtual machine can change or damage your real computer, or its software.
