> Will it ever be possible to run a 64-bit guest kernel under a 32-bit > (PAE) Xen and domain0 ? It seems pretty unlikely. The guest kernel would be expecting 64-bit virtual addressing, 64-bit registers, etc, which just wouldn't be available on a CPU which wasn't in (or didn't have) 64-bit mode. Supporting non-PAE 32bit kernels on a PAE hypervisor, and maybe supporting 32-bit kernels on 64-bit Xen are rather more likely. i.e. being able to run a guest on a hypervisor that only uses *more* features of the hardware. The first effort in this direction may be (something like) supporting non-PAE guests on a PAE hypervisor. Cheers, Mark -- Dave: Just a question. What use is a unicyle with no seat? And no pedals!
