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!

James
