Wondering if I can get some opinions on dom0 CPU pinning and xm weighting. We have several xen servers on SLES11SP1 and up to this point we have never done anything with pinning CPU''s to dom0. We''re trying to decide if we should be doing that. Same goes for xm weighting (if I''m saying that correctly). For example, running the following command when a xen server boots. xm sched-credit -d domain-0 -w 512 We found the weighting mentioned in some documentation. Any help or thoughts are appreciated!
