[Xen-tools] What''s the main difference between BVT and EDF?,
Hi folks BVT and EDF are both xen scheduler. It is expected that administrator will choose the scheduler most appropriate to their application and configure the machine to boot with that scheduler. I just wonder What''s the main difference between BVT and EDF? What kind of scenario to use them? Thanks _______________________________________________ Xen-tools mailing list Xen-tools@lists.xensource.com http://lists.xensource.com/xen-tools

They''re both buggy. The new scheduler is supported by us, automatically load balances on SMP systems, and has a simpler administrator interface. Once credit scheduler has demonstrated its stability we''ll most likely remove the other two schedulers. -- Keir _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel
