We could provide flags to represent useful configurations: e.g., run on all CPUs atomicaly, run on CPU0 only and quiesce others, etc. I thought the goal of Jan's proposal was to have Dom0 take over this kind of thing, not extend Xen to do it. So his idea of getting CPUs in a known state, then letting Dom0 handle it, is different, is it not? Does this really address his problem? ron _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel |
