Memory Utilization reports in for HyperV Guest Machine with Dynamic Memory Option is not reading the Maximum Memory, insisted is reading the currently assigned memory which lead to give wrong Memory Utilization reports,
I have opened a case (Case # - 00048598) regarding this issue and the issue was with the WMI Query need to be modified to get the Maximum Memory insisted of Currently assigned.
So they suggest to open a Feature Request to modify the WMI Query and related reports.
