Hi Stefan and list,

Is there special magic necessary to boot a Xen dom0 from FILO (0.5)?
I've not
tried myself (I will tomorrow!) but my colleague says that when he tries
boot Xen 3 via the xen-3.gz image (with Grub support enabled in FILO),
just gets 'unsupported format'.

Is that a known problem? I only found this 2 year old thread via Google
talks about Xen2, and predates Filo's Grub support I believe:
