QEMU can run of real file systems just fine - just point it to a device
file instead of disk image. Of course, you should not expect it to run
an OS that was not installed trough QEMU itself.
By the way, QEMU is an emulator, not virtualizer. The OS inside QEMU is
almost totally isolated from your real hardware.

Xen runs at native performance, QEMU does not.
QEMU can run any OS, Xen cannot.
