Didn''t see a reply to this, so...

I''m not sure what the absolute maximum is but you can configure it
above the
number of physical CPUs in the system (if you really want ;-)

Yep, I believe there''s CPU hotplug support in there. You should be
able to
add / remove CPUs using an xm command, although I''ve not tried it.

Probably both, although again I''ve not checked. If it hooks into the
standard
Linux hotplug CPU patch, the guest can do it at its discretion.

For number of CPUs? That''d probably be sensible, guests certainly
won''t be
able to exceed a given allocation. You''ll also be able to tweak the
scheduling parameters to determine how the virtual CPUs are scheduled, i.e.
how "good" the CPUs the domain sees are.
Cheers,
Mark
