User Mode Linux: Anybody Tried It Yet ?

Recommended Posts

Hi guys,

Just today while browsing Sourceforge I came across this software called User Mode Linux.

 

Here's a short intro. straight from their site:

    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.

 

Source: http://user-mode-linux.sourceforge.net/


This seems to be the mini brother of VMWare. My question is has anybody tried this out yet - and can give me some sort of a comparative review of this one and VMWare ? I'd really like to know. I was thinking of designing something similar to this for Windows, some cut-down version of a Virtual Machine, that'll enable you to test all the downloaded software - that way you are free to keep ONLY the one's which you find useful and not worry about your registry getting filled with chunks and chunks of useless trash.

 

Cheers,

m^e

User mode linux if not an emulator / virtual machine.
User mode linux is simply a kernel that runs in userspace, rather than kernel space.

Usermode Linux was origonally designed to allow Linux Kernel hackers to test kernels without having to re-boot.

It is a bit like a chroot environment, with its own kernel.
To be honest, unless you are planning on kernel hacking, there is no advantage to usermode linux over using chroot.

DESCRIPTION
      chroot  changes the  root  directory  to that specified in path.  This
      directory will be used for path names  beginning  with /.  The  root
      directory is inherited by all children of the current process.

You may want to look at coLinux. Its an OpenSource emulator to run Linux on Windows.
