This sounds very much more like a KVM system... The majority of Xen becomes the 'kernel and QEMU' part (i.e. it's the part that boot-straps the system, deals with IOMMU, APICs, etc. and incorporates the scheduler) and the tiny hypervisor is the 'kvm.ko' (deals with basic I/O and instruction emulation traps). Is that the general split you envisage?
