xen installation error: error 13: invalid or unsupported executable format
 

Dear friends,

I am following the instruction on www.fedoraproject/wiki/fedoraXenQuickstart.
After installing the rpms for xen, kernel-xen0, kernel-xenU and reboot the pc then on entering the xen kernel, i got this error:

Error 13: Invalid or unsupported executable format. Press any key to continue.

After pressing any key, it returned to the kernel option menu again.
Anyone has any idea what might be the problem?
I have no idea what does the error message mean....

thanks for taking time reading my thread.

Regards
Y
