Measures reported by HvMemReserveTest

As Hyper-V can dynamically allocate memory to virtual machines on demand, the host needs to ensure that some memory is kept for itself. Without which, Hyper-V may allocate a lot of memory to the VMs, starving the host of adequate memory resources. As a result, the host may start performing poorly. To avoid this, administrators need to time and again check the amount of memory that the host has set aside for its use.

This test periodically reports the amount of memory that the host has reserved for itself, thus enabling administrators to periodically check whether the host has sufficient memory for its own operations.

The measures made by this test are as follows:
