I think it's possible to shut down domain0 and leave other domains running,
isn't it? Just besides the sende of this :)

If this is possible, i see a more generic quistion on how about handling
domain0. One might want to set up all domains and then terminate the
"controlling master" if this is somehow possible (don't know if i tried this
with Linux so far).

If it's not possible, i also think we should separate reboot/halt here (i wrote
about this issue in my patch mail). For now i didn't think about the
differentiation between Dom0 and DomU at this place. SCHEDOP_yield() on halt
(looped), SCHEDOP_exit on reboot (as Xen reboots automatically afterwards,
which is also configurable i think)
