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
