Kurt, could you please retest with today's unstable? I have put your first patch in (thanks for that) and we have made some changes to the xenstore watch interface recently, so that may help with the second problem. The idea is that the memory/target value gets written by Xend, and and the balloon driver holds a watch on that value in the store. When the watch fires, the balloon driver should respond by setting the new target (drivers/xen/balloon/balloon.c:watch_target). Watches have been broken in various ways over the last few days, and the bugs we know about there have now been fixed, so I would be interested to know whether your bug has been fixed in the process. Cheers, Ewan. _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel
