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
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
- Using the updated Remote Server Administration Tools (RSAT) for Windows 7 & Windows 7 SP1
- System Center Virtual Machine Manager 2008 R2 SP1
- System Center Virtual Machine Manager 2012 Beta
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.
