RE: [Xen-ia64-devel] [Patch] booting Guest domains w/o initrd on RHEL4

["Magenheimer, Dan (HP Labs Fort Collins)" <dan.magenheimer@xxxxxx>]

This is the same point I got to when I tried this two weeks
ago.  I think the problem is that just like dom0 requires
an initrd to boot RHEL4, domU also requires an initrd to
boot a RHEL4 image.  I don't think initrd for domU is
implemented yet.
