Is it a generally held belief that this arrangement is a good thing? Or does it just assume that I won't do anything silly like xen recompiles under dom0? The default basically assumes that dom0 is a server for other domains, so you want to favour it if it's runnable. There isn't much science behind that choice of default, I can assure you. :-) -- Keir _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel |
