I believe we will be testing and running a xenbits pv_ops-based tree within 6 months, yes. Obviously we will have branches containing patches not yet in, or perhaps suitable for, upstream. Actually I hope we can move decisively towards this in the next couple of months, once Jeremy has the basic dom0 stuff working well enough. -- Keir _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel
