There's already some BIOS-configuration logic in libxl (see
libxl__domain_bios()) which I would assume you hook up to. Ian Campbell
would know better -- he wrote it.
I'd probably prefer to let xend grow obsolete quietly than add further
features. Noone's maintaining it to fix it up if new features break it. No
strong opinion on that though, it's up to the tools maintainers.
