[Xen-devel] RE: [PATCH][RFC] to fix xm list memory reporting

["McAfee, Tommie M" <Tommie.McAfee@xxxxxxxxxx>]

patch updated to use domain_getinfo.

The balloon driver's write to xenstore is now a means of notification that the 
requested allocation has finished and that it is time to update 
self.info['memory'] using domain_getinfo.
