Hi Vang,
Sorry for delay in replying to you.
Thanks for including the contents of the ramdisk, too.
It all looks OK to me. The grub stanza is good; you're not missing any
specified /boot files; the files in lib/* appear to be the ones needed
for raid and lvm.
You should be able to use a "xenified" kernel to boot without the xen
hypervisor. You might want to try that first to prove that it boots
correctly before moving onto a xen hypervisor boot. Below is what that
grub stanza should look like.
title Fedora Core (2.6.15-1.2054_FC5xen0)
root (hd0,0)
kernel /vmlinuz-2.6.15-1.2054_FC5xen0 ro root=/dev/XenVol/MgtRootVol
module /initrd-2.6.15-1.2054_FC5xen0.img
That may help. Sure hope so !-)
