Hi, I work wtih Xen in Quad IA 64, and may question is under the BVT: Xen scaling processes between processors or Xen scaling VMs between processors? For example, I have 4 MV, this MV are load balanced between the processors or just his processes are distributed? thanks _______________________________________________ Xen-ia64-devel mailing list Xen-ia64-devel@lists.xensource.com http://lists.xensource.com/xen-ia64-devel

I think you''re asking if the schedulers in xen schedule domains or processes and if that''s the case, I have the answer: They schedule domains or, more accurately, they schedule VCPU''s which are assigned to domains. The kernel in the domU schedules processes within itself. If you see the term "process" in a variable name or comment in xen-level scheduler code, consider it synonymous with the term "VCPU."
