You mean running Xen within QEMU? It does, but you need to use a multiboot
loader and QEMU does not seem to support that. You can create an
.iso image with isolinux that loads mboot.c32 for that.

If you want to use qemu like that in Xen environment you can do it too.
Just need the upstream version and use -M xenpv
