James, I have been testing version 0.10.0.134 today with very good results. Clearly, whatever was causing my live-migration problems has been fixed. Keith, thanks for cluing me in on those other discussions. Sounds to me like there is some uncertainty about the expected behavior which is unresolved. I will stay tuned to that. Best wishes. -- Charlie _______________________________________________ Xen-users mailing list Xen-users@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-users
