5.3 Viewing Dynamic Memory at work
Sometimes small changes make a big difference in the usability of a
user interface feature. In the Hyper-V Manager of Windows Server 2008
R2, you could monitor in real time how much physical memory was
allocated to each VM that had Dynamic Memory enabled on it. This
real-time allocation amount is called the assigned memory. In addition, you could monitor the memory demand (the total committed memory) and the memory status (whether the current amount of memory assigned
to the VM as a buffer is sufficient) for the VM. The problem, though,
was that these real-time measurements were displayed as columns in the
Virtual Machines pane of Hyper-V Manager, which meant that you had to
scroll horizontally to see them.
Hyper-V in Windows Server 2012 adds a series of tabs to the bottom
central pane, and by selecting the Memory pane, you can view the assigned memory, memory demand, and memory status for the selected VM quickly (see Figure 7).
You also can use the Get-VM cmdlet in PowerShell to display these same real-time measurements, as shown in Figure 8.
