Installed Fedora 9 with an Xen kernel, the grub boot entry has a wrong xen image
Other wise, grub complains with an 'Error 15: File not found' message
After booted to the correct xen image file, the system hangs. The screen shows

Keyboard LED is not responsive to Numlock key press. I had to hard reset the

Is this reproducible?
Describe the steps:
1. Install Fedora 9, make sure to select the Xen kernel and Xen support
2. Boot to Xen kernel

I didn't select not to install the generic kernel. But the grub only comes with
a xen-kernel. So I'm not able to boot into the system. 'Tab' on the grub edit
prompt also shows that the /boot doesn't have the generic kernel.
See if the entry in grub helps since I cannot copy the grub.conf inside the system:
module /boot/vmlinuz-2.6.25-0.2.rc4.fc9xen ro

I am able to reproduce the issue locally. I tried both custom partition layout
as well as the automatic partitioning. Both didn't have an effect on this.
Xen dom0 is not supported in Fedora 9, only DomU guests will be supported
The xen.gz is left in the RPM since we may be able to re-introduce Dom0 support
post-GA, or in F10
Until that time though, it is expected that booting Xen will hang.

Yes. That's where we can push. Thanks for the help!
