As you all know that SP1 for Windows Server 2008 R2 and Windows 7 just gone RTM adding two new virtualization capabilities: Dynamic Memory and RemoteFX
Let’s first understand these capabilities in details.
Dynamic Memory: An enhancement to Hyper-V R2, Dynamic Memory pools all the memory available on a physical host. Dynamic Memory then dynamically distributes available memory, as it is needed, to virtual machines running on that host. Then with Dynamic Memory Balancing, virtual machines will be able to receive new memory allocations, based on changes in workload, without a service interruption.
