If we expect a lot of tweaking from user-space tools, then we should go with 3. If we expect people to set parameters and then leave them alone, we should go with 1. -George _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxx http://lists.xen.org/xen-devel
