Well, I believe the issues are sorted out for paravirtualised guests at least. Maybe there are lurkers for HVM guests -- if so, and they're of the scale of hangs and softlockups, we'd really like detailed info so we could try to repro. Some HVM instability is also doubtless due to the current rate of churn in the unstable tree, which will be carrying on for at least another week (while more pv driver and shadow mode patches are applied). -- Keir _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel
