Over time we had kernel problems in that area, so much would depend on when exactly you found it necessary to switch. Also I don't think your reply really demonstrates any observed misbehavior with the pv-ops kernel, yet that's the only criteria based upon which fixing that kernel or considering to re-introduce that control would become possible routes forward. > After a lot of research, we switched to using > independent_wallclock for all guests. Afair, this was/is also the > SUSE/Novell recommendation. Not as far as I know. As long as there are no bugs, running e.g. NTP once in Dom0 would seem the more efficient model compared to running it in every DomU. But of course I don't know who gave this recommendation, and in which context that was. Jan -- To unsubscribe, e-mail: [email protected] To contact the owner, e-mail: [email protected]
