work in progress hypervisor for learning purposes but also hoping to build something around it in the future.

• apic virtualisation is very initial and only includes TPR shadowing. It technically works for a very short period but then the cpu hard faults. Ive tried to reference freebsd and linux but i cant seem to get it consistently working and the manual is fairly vague when it comes to TPR shadowing.
• unconditional io exiting is buggy and will crash u

windows versions

ive only tested it on win10 22h2, so use are ur own risk
