I'm kind of new to this area, so I'm trying to get my head round a few things. I think the issue lies in me needing a initrd, I need to supply that with the xenu to boot the rhel 3 distro. I ran the following: touch /lib/modules/2.6.11-1.1369_FC4xenU/modules.dep mkinitrd /boot/initrd-2.6.11-1.1369_FC4xenU.img 2.6.11-1.1369_FC4xenU I then put this ramdisk in the rhel-3-es xen file kernel ="/boot/vmlinuz-2.6.11-1.1369_FC4xenU" ramdisk = "/boot/initrd-2.6.11-1.1369_FC4xenU.img" memory = 260 name = "rhel-3-es" nics = 1 disk = ['phy:hda3,sda1,w'] root = "/dev/sda1 ro" But when booting up rhel-3-es doesn't, it gives the following message: xm create -c rhel-3-es Using config file "/etc/xen/rhel-3-es".

I'm pretty sure its to do with using a 2.6 kernel image having troubles with booting a 2.4 kernel. Which is exactly what you said Daniel. The problem is I don't know how to make an initrd that will work under rhel-3-es or any other 2.4 kernel distro. I would be really grateful if someone could show me how to do this. I know this may be basic for you guys on the list, but I'm really stumped for ideas. I appreciate your help.
