User Mode Linux on Red Hat Linux

Hi

I'm trying to install User Mode Linux (http://user-mode-linux.sourceforge.net) on my Red Hat 8.0 server.

I used an RPM (user_mode_linux-2.4.19.5um-0.i386.rpm) to do this, and tried use various bootable root filesystem from the downloads section of the web site.

Right at the very end of the boot process, I would get a "xterm Xt error: Can't open display:" error... I got this error using the RH7.2, Debian Woody and Mandrake 8.2 bootable root filesystems.

I decided to try this on a Red Hat 9.0 server, again, using the RPM. I didn't even get close with this, as a the boot process is interrupted quite early with a "Kernel panic: outer trampoline didn't exit with SIGKILL" error. Apparently, this is a bug with the RPM version of User Mode Linux, and the kernel in Red Hat 9.0

My question:

I'd like to install this from source, but have no idea what to download, where from and how to compile it. The UML site says I need should get the 'latest UML patch and matching kernel pool, and building an up to date UML kernel'.

I'm really not sure what to download and where from. There are instructions to compile the kernel here, http://user-mode-linux.sourceforge.net/UserModeLinux-HOWTO-2.html, but I'm not sure what I should be doing. I've tried to find newer RPM's, but 2.4.19-5 seems to be the last produced version.

I'd prefer to do this on a Red Hat distribution, either 8.0, 9.0 or Enterprise 3.0 ES.

Any guidance much appreciated.

In typical unix geek style, the default uml kernel available for download from the main site is broken. Obviously you should compile your new uml kernel while working on a quantum physics problem. In hexedecimal.
Try http://kernels.usermodelinux.org/kernels/linux-2.4.22-8um/linux
You may need to make it executable after down loading it. Chmod +x linux should do the trick.

The kernel on my server (from uname -a) is 2.4.21-4.ELsmp .... does it matter that the kennel you suggested was 2.4.22-8um.

Do I simply download it and execute it?

Thanks

It doesnt matter what kernel you are running on your server.
