Description Paolo Bonzini 2009-12-07 04:47:33 EST
> latest grub had changed to "don't pass filename in multiboot
> command line".
> The old cmdline format is: "module-name options..."
> The new cmdline format is: "options..."
> So xen + grub2 always loss the first option, because xen will
> skip the first option.

Can be tested by installing e.g. RHEL5 and Ubuntu 9.10 on the same boot block.

The thread including http://permalink.gmane.org/gmane.comp.emulators.xen.devel/75161 outlines two possible approaches.

This problem was fixed in upstream grub-2 (bzr revno 2480):

2010-06-28  Vladimir Serbinenko  <phcoder@gmail.com>

        XEN with Linux grub-mkconfig support.

        * conf/common.rmk (grub-mkconfig_SCRIPTS) [linux]: Add 20_linux_xen.
        * util/grub-mkconfig.in: Export GRUB_CMDLINE_XEN and
        * util/grub.d/20_linux_xen.in: New file.

Did you test it?  If you didn't, this should be reopened as TestOnly.
Comment 4 Laszlo Ersek 2011-06-27 07:58:04 EDT
