Good day. I''m testing live migration (infinitive migration in loop), and I found sometimes in dmesg of guest machine (2.6.34-xen from SUSE) following message: [35993.646804] XENBUS response ring is not quiescent (00058e85:00058eac): fixing up [36172.534582] XENBUS response ring is not quiescent (000675f9:00067620): fixing up [36228.133259] XENBUS response ring is not quiescent (0006debf:0006dee6): fixing up [36410.791326] XENBUS response ring is not quiescent (00082dd2:00082df9): fixing up [36572.713538] XENBUS response ring is not quiescent (0009521c:00095243): fixing up [36627.399482] XENBUS response ring is not quiescent (0009bae2:0009bb09): fixing up [36689.311589] XENBUS response ring is not quiescent (000a2382:000a23a9): fixing up AFAIK this message meaning underflow or overflow of ring buffer for xenstore. But I do not understand consequences for domU... What happens if ring buffer found over(under)flowed? Some device requests will be dropped, or some response will be lost? Or dom0/domU kernel have some kind of queue for those requests? _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
