I agree that this is harsh, but it's quite difficult to undo the page exchange that was previously done up to the point of failure. And a pinning error can only be caused by a misbehaviour of the guest. Overall this is a simple solution to a difficult problem. I'll make the changes according to all the comments, thanks. _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxx http://lists.xen.org/xen-devel
