Currently 0 = Xen 3.0, 1 = VMI. I think this is a really really bad idea because you're requiring that all operating systems agree on these values or you impose it upon the hypervisor's domain builder to be operating system specific. I really don't think either of those are very appealing, especially considering that there's a much simpler solution using hypervisor specific entry points. That said, %ebx = 0 works for us, so maybe I should just not care... Christian
