Virtualization Nation,
The good news just keeps coming and we’re pleased to keep the momentum rolling with the latest release of our rock stable, feature rich, standalone Microsoft Hyper-V Server 2008 R2 with Service Pack 1! For those who need a refresher on Microsoft Hyper-V Server 2008 R2, it includes key features based on customer feedback such as:
-
Live Migration
-
High Availability with Failover Clustering
-
Cluster Shared Volumes
-
10 Gb/E Ready
-
Processor Compatibility Mode
-
Enhanced Scalability
-
…and much more.

Service Pack 1 for Hyper-V Server 2008 R2 includes all the rollup fixes released since Microsoft Hyper-V Server 2008 R2 and adds two new features that greatly enhance VDI scenarios:
-
Dynamic Memory
-
RemoteFX
After installing the update, both Dynamic Memory and RemoteFX will be available to Hyper-V Server. These new features can be managed in a number of ways:
-
Using the updated R2 SP1 Hyper-V Manager user interface on a full version of Windows Server 2008 R2 SP1
-
-
-
Dynamic memory is an enhancement to Hyper-V R2 which pools all the memory available on a physical host and dynamically distributes it to virtual machines running on that host as necessary. That means based on changes in workload, virtual machines will be able to receive new memory allocations without a service interruption through Dynamic Memory Balancing. In short, Dynamic Memory is exactly what it’s named. If you’d like to know more, I've included numerous links on Dynamic Memory below.
Configuring RemoteFX with Microsoft Hyper-V Server 2008 R2 SP1
Although using Dynamic Memory does not need any additional server side configuration beyond installing the R2 SP1 update, enabling RemoteFX does require some additional configuration on the host. The exact steps for enabling the RemoteFX are detailed below:
1) Verify the host machine meets the minimum hardware requirements for RemoteFX.
2) Verify the host has the latest 3D graphics card drivers installed before enabling RemoteFX.
3) Enable the RemoteFX feature using the following command line:
Dism.exe /online /enable-feature /featurename:VmHostAgent
4) From a remote machine running the full version of Windows Server 2008 R2 SP1 or a client OS running the latest version of RSAT, connect to the Hyper-V Server machines, create a Windows 7 R2 SP1 virtual machine and under “Add Hardware”, select “RemoteFX 3D Video Adapter”. Select “Add”.
If the “RemoteFX 3D Video Adapter” option is greyed out, it is usually because RemoteFX is not enabled or the 3D video card drivers have not been installed on the host yet. Before attaching the RemoteFX adapter , make sure to set user access permissions, note the computer name and enable Remote Desktop within the VM first. When the RemoteFX 3D video adapter is attached to the VM, you will no longer be able to connect to the VM local console via the Hyper-V Manager Remote Connection. You will only be able to connect to the VM via a Remote Desktop connection. Remove the RemoteFX adapter if you ever need to use the Hyper-V Manager Remote Connection.
How much does Microsoft Hyper-V Server 2008 R2 SP1 cost? Where can I get it?
Microsoft Hyper-V Server 2008 R2 SP1 is free and we hope you enjoy it! Here’s the download link: Microsoft Hyper-V Server 2008 R2 SP1 .

Part 1: Dynamic Memory announcement . This blog announces the new Hyper-V Dynamic Memory in Hyper-V R2 SP1. It also discussed the explicit requirements that we received from our customers. http://blogs.technet.com/virtualization/archive/2010/03/18/dynamic-memory-coming-to-hyper-v.asp...
Part 2: Capacity Planning from a Memory Standpoint . This blog discusses the difficulties behind the deceptively simple question, “how much memory does this workload require?” Examines what issues our customers face with regard to memory capacity planning and why. http://blogs.technet.com/virtualization/archive/2010/03/25/dynamic-memory-coming-to-hyper-v-par...
Part 3: Page Sharing . A deep dive into the importance of the TLB, large memory pages, how page sharing works, SuperFetch and more.
