There are not many differences in the device emulation between qemu
mainstream and xen now.
I think Windows would complain even if you try with a brand new qemu
compiled from svn, because your image is probably too old (created with
a too old qemu).

If you want to be sure which device caused it you can try booting linux
on your qemu and on xen and do an lspci -vvv on both.
