[Xen-users] Using mainline PVM

[Joel Becker <Joel.Becker@xxxxxxxxxx>]

Hey folks,
        I have a non-VT/Pacifica box.  I have happily running PVM domUs
with distro kernels.  I need to test some mainline code (unrelated to
virtualization).  Xen 3.1 x86_64 in dom0.  So, I build a mainline 32bit
kernel with CONFIG_XEN.  The files in arch/i386/xen seem to be built
just fine, but I can't figure out what object to boot.  bzImage fails
with:

----------------------------------------------------------------------
Error: (2, 'Invalid kernel', 'xc_dom_find_loader: no loader found\n')
----------------------------------------------------------------------

        I also tried vmlinux.bin, which gets the same.  I tried
arch/i386/boot/compressed/vmlinux, but that gets:

----------------------------------------------------------------------
        Error: (2, 'Invalid kernel', "elf_xen_note_check: ERROR: Not a Xen-ELF 
image: No ELF notes or '__xen_guest' section found.\n")
----------------------------------------------------------------------

        Lastly I tried vmlinux from the toplevel kernel source
directory, and that just appears to hang the domU.
        What am I doing wrong?  Is there a particular make target I'm
supposed to use?  A particular kernel image file I'm not seeing? 

Joel
