An important thing to note is that support in Xen userspace to boot from a bzImage is fairly new - so if you have any existing Xen based products/distros you should check that it has bzImage support if you want to be guarenteed able to boot mainline kernels. We're pushing updates to existing Fedora/RHEL Xen userspace RPMs to enable bzImage support. IIRC the primary changeset you'll need from xen-unstable is this one: changeset: 17332:db943e8d1051 user: Keir Fraser <[EMAIL PROTECTED]> date: Tue Apr 01 10:09:33 2008 +0100 files: tools/libxc/Makefile tools/libxc/xc_dom_bzimageloader.c tools/libxc/xc_dom_elfloader.c description: x86: Support loading Linux bzImage v2.08 and up. The latest -mm kernel (2.6.25-rc3-mm1) contains v2.08 of the Linux bzImage format which embeds an ELF file in place of the raw payload allowing it to be extracted and used by the Xen domain builder. It is expected that this functionality will be put forward for 2.6.26.
