Quite a few maintainers replied, and a few others, too. Thank you!

I still have to fully digest the replies, in particular whether there's
enough detail for me to actually boot a guest.

I'm still lacking information on 26 machines. If you're cc'ed, you're
considered a possible source of information. Please help.

If you're a supporter or maintainer, but can't help, please consider
adjusting MAINTAINERS to S: Odd Fixes for the machine.

Machines with at least one supporter:

Re: [Xen-devel] [Qemu-devel] Maintainers, please tell us how to boot your machines!
