Explanation

Hyper-V Dynamic Memory Overview Minimum memory configuration with reliable restart operation As in the previous version of Dynamic Memory, you can configure a minimum memory amount for virtual machines, and Hyper-V continues to ensure that this amount is always assigned to running virtual machines. To provide a reliable restart experience for the virtual machines configured with less minimum memory than startup memory, Hyper-V uses Smart Paging. This memory management method uses disk resources as additional, temporary memory when more memory is required to restart a virtual machine. This approach has advantages and drawbacks. It provides a reliable way to keep the virtual machines running when there is no available physical memory. However, it can degrade virtual machine performance because disk access speeds are much slower than memory access speeds.
