Hi yep, I've started from scratch again, cos I got fustrated with it. Basically I'm now trying to run the 2.4 kernel on FC4. I got the kernel from the xen site i.e 2.06. the problem is that it won't boot. It keeps crashing saying something like "Xen will only boot images made for xen 3.0" Here's what I did Currently I am running fedora core 4 with kernel 2.6.11-1.1369_FC4xen0 mkinitrd /boot/initrd-2.4.30_xen0.img 2.4.30-xen0 I then added this to /etc/grub.conf title Xen (2.4.30-xenU) root (hd0,0) kernel /xen.gz dom0_mem=150000 module /vmlinuz-2.4-xen0 ro root=LABEL=/ module /initrd-2.4.30_xen0.img and then reboot. Any idea where the problem is?
