It would be helpful to give their addresses so we know which documents did you read. For instance, http://uml.nagafix.co.uk/ gives very simple instructions: ./kernel ubd0=./root_fs if you tried something like that and it failed, please post the error messages. Also, give more details on the host system (for instance, there is a Debian-specific problem with 2.6 so knowing the OS you use could be useful). |

Hi Mr.Stephane, Thank you,for your reply.....and my host system is redhat linux 2.4.20-8 on i386. My question is very simple as i know that root file system for booting linux(O.S) is must ,since it needs to mount basic information of O.S.But why should we need a seperate file system for UML. i have followed the basic steps:- 1.Download linux kernel Image. 2.Add skas patck for that kernel to increase the speed. then compile the kernel.....then where comes the file system for UML. then can you tell about UML Utillityes?what are they? Please reply....... rgds, sai On 11/8/06, Stephane Bortzmeyer <ste...@bo...> wrote: > On Tue, Nov 07, 2006 at 11:42:48PM +0530, > battipatisainagendra Bhavaniprasad <sai...@gm...> > wrote > a message of 21 lines which said: > > > can any one help me in installing user mode linux on linux 2.4.20. > > It would be helpful to explain what you already did. > > > I need any UML image to be instaled > > In my experience, the "blaisorblade" kernels in > http://www.user-mode-linux.org/~blaisorblade/binaries/ work fine.

I must confess that I have a lot of trouble understanding your text, probably because english is not my native language. > But why should we need a seperate file system for UML. Each Unix machine (even if it is a virtual one) needs a separate file system, otherwise, what would happen of /var/log/messages? Everyone would write randomly in it? If disk space is scarce, the COW filesystem of UML is a good solution. > then where comes the file system for UML.

They allow you to create COW filesystems, to set up networking (the TAP device and so on) or other miscellaneous things. > Please reply....... Hmmm, sorry but I am not paid for that. |

First, just get the thing booted - download a kernel and filesystem and watch the thing boot then, get a recent kernel from kernel.org, build UML from it, then boot that the utilities will be needed when you want to put it on the net - http://user-mode-linux.sourceforge.net/new/uml_utilities_20060622.tar.bz2 Save the skas patch for later, when you have your UMLs running happily, doing whatever they need to be doing.

What filesystem did you think UML was going to boot? See http://user-mode-linux.sourceforge.net/new/index.html for booting UML. You can skip the part about downloading the kernel since you already have it, but pay attention to the filesystem and the command line. Jeff |

I would suggest you start with a prebuilt root filesystem to get things going. You can download one from uml.nagafix.co.uk. I believe that the preset login on those images is "root" with no password. I would also recommend that you not email the list until you have spent a fair amount of time searching the web (and the archives of this list) for your answer. Take at least 4-5 hours to search the web before you ask a question. You will get your answers quicker, and you will not have spent the time of all the people on this list for basic questions. I would also highly recommend Jeff Dike's book "User Mode Linux". It helped me get set up rather quickly, and answered many questions I could not find answers to any other place. It will step you through the setup of your first UML, and tell you what to type in many cases.
