im using fedora10.
i have downloaded the uml and unzib then
run as
host% chmod 755 ./linux-2.6.24-rc7
host% ./linux-2.6.24-rc7 ubda=FedoraCore5-x86-root_fs mem=128M

it gives the segmentaion fault error

Please give more detail. What is the package 'uml' that you are referring to?

on search i found that for user mode linux we need to have
source kernal, filesystem and UML utilities
i downloaded the above bt didnt work can u give me the precise way to install User mode Linux in Fedora10. and how to configure
thanks

take a look at this: http://fedorasolved.org/installation...-Linux-Install
Google is your friend!

thanks

dear i tried another procedure mentioned at http://hanez.org/howto-user-mode-linux.html
as under

[safi@safi ~]$ mkdir linux
[safi@safi linux]$ wget http://kernel.org/pub/linux/kernel/v....23.13.tar.bz2
[safi@safi linux]$ tar -xjf linux-2.6.23.13.tar.bz2
[safi@safi linux]$ cd linux-2.6.23.13
To build the kernal
[safi@safi linux-2.6.23.13]$ make ARCH=um defconfig
To compile the kernel
[safi@safi linux-2.6.23.13]$ make ARCH=um

arch/um/sys-i386/ptrace_user.c:12:22: error: asm/user.h: No such file or directory
make[1]: *** [arch/um/sys-i386/ptrace_user.o] Error 1
make: *** [arch/um/sys-i386] Error 2

[safi@safi linux-2.6.23.13]$ ./linux
bash: ./linux: No such file or directory

i dont know what to do?? please guide me...

Installing a kernel that is older than the release kernel on a RPM based system is virtually impossible. There are too many things in the system that require the features that are in the newer kernel but not in the older kernel.
