Re: [Xen-devel] Consideration of cpu-processing in domain-0 by credit scheduler

[George Dunlap <George.Dunlap@xxxxxxxxxxxxx>]

At the moment, there is no consideration of work done in dom0 on
behalf of a guest domain, and no work planned as of yet.  Long-term,
the plan is to use stub domains, and potentially have some kind of
"co-scheduling", where work done in the stub domain is counted as part
of the guest VM.  That still doesn't account for work done in back-end
drivers, of course.
