Sure. You just need to support PCI drivers, ACPI, IOAPIC, IRQ, MSI/MSI-X and
naturally the hypercalls. Then you also need to support booting the kernel
from protected mode and parsing the DIRECTMAP_P2M array for your MMU code.

Ah, and be able to work with events (which is an IRQ mechanism for PV
guests). 

Oh, and packages the RTOS kernel in an ELF format.

I think that covers it.
