In order to move the hypervisor specific parts of the VM exit handling path, we're defining a generic, hypervisor agnostic VM exit enum. This is what the hypervisor's Vcpu run() call should return when the VM exit can not be completely handled through the hypervisor specific bits. For KVM based hypervisors, this means directly forwarding the IO related exits back to the VMM itself. For other hypervisors that e.g. rely on the VMM to decode and emulate instructions, this means the decoding itself would happen in the hypervisor crate exclusively, and the rest of the VM exit handling would be handled through the VMM device model implementation.
