Description of problem: System will not boot after installing. Steps: In Fedora Core 9 preview. Do a custom install and select components you want, select Xen kernel, install as normal. At first boot, you will be not able to boot because error: kernel /boot/xen.gz-2.6.25-0.24.rc9.fc9.i686 Error 15: File not found Version-Release number of selected component (if applicable): Fedora core 9 preview Solution: You can edit grub by pressing key e and modify the line like this: kernel /boot/xen.gz-2.6.25-0.24.rc9.fc9.i686.xen then the system will boot. Someone forget to add the .xen extension in the grub menu. I must also say that my system hangs after loading Xen kernel, last message is: (XEN) Xen is relinquishing VGA console. But this problem may not be related to then .xen extension missing. May be there are more parameters after .xen ?
The Xen Dom0 host is *NOT* supported in Fedora 9 http://fedoraproject.org/wiki/Features/XenPvops It may be re-introduced in FEdora 10 http://fedoraproject.org/wiki/Features/XenPvopsDom0
