In other word, would you say it is something in rc5 that is introducing this behavior, which was not happening of earlier versions?

Well, we absolutely need serial output (either of the guest, of the host, or of both) to be able to tell.

I am interested in and did ask why you tested Credit2, how you tested it, and how you do find it, though, if you're keen on sharing that. :-D Thanks and Regards, Dario -- <> (Raistlin Majere) - Dario Faggioli, Ph.D, http://about.me/dario.faggioli Senior Software Engineer, Citrix Systems R&D Ltd., Cambridge (UK) signature.asc Description: This is a digitally signed message part ___ Xen-devel mailing list Xen-devel@lists.xen.org https://lists.xen.org/xen-devel
