Dynamic Memory is a memory allocation feature for Microsoft
Hyper-V which pools the host's memory and sends resources to virtual machines (VMs) that
need it. When Hyper-V Dynamic Memory is enabled, the VM declares how much memory it needs and
the host provides that quantity plus an extra amount to be used as a buffer.
Dynamic Memory, which can be compared with Vmware’s memory overcommit feature,rebalances the
host's memory in one-second intervals and allows VMs to be prioritized in terms of memory
usage.
