Depends ;)

Long term plan is to have three ways of supporting xen guests in qemu
(pv only for now):

#1: Xen emulation (aka xenner).  No code for this is submitted (yet).
    That will allow running xen kernels in qemu.  No xend, no xenstored
    needed.  Also no Xen hypervisor.

#2: Make qemu attach to an existing domain.  That is the way qemu-dm
    (xenified qemu version) works right now:  xend creates the domain,
    and qemu attaches to it to provide console and framebuffer backend.
    Obviously needs both xend and xenstored.

#3: Make qemu create xen domains.  xenstored is still needed then.  You
    can run without xend though.

#2 works with the first 4 patches applied.
#3 works with all patches applied.
#1 needs more patches which are bitrotting in my git repo right now.
   I'll dig them out once this patchset is merged.

cheers,
  Gerd
