Fedora Kernel upgrade and Xen

By Shahram Javey

Each time you update the Fedora kernel, e.g., by using yum update, the file /boot/grub/grub.conf gets updated to use this kernel. This may result in you being unable to boot with Xen. The solution is to modify the grub.conf file and move the Xen kernel to the top of the file, e.g. tonight when I updated Fedora 8, the new kernel was placed a head of the Xen kernel. So you’ll need to edit this file and put the Xen kernel ahead of the latest Fedora update.
