Logoff the Windows 7 SP1 session.
In summary, the RemoteFX feature allows Windows 7 SP1 and applications running in virtual machines to provide the same user experience as though they were running on a physical computer. The Remote FX feature The RemoteFX feature also allows remote users to redirect local USB devices to their Remote Desktop sessions. The proceeding steps help show how RemoteFX improves the user experience when running Windows 7 and applications in a virtualized environment.
Dynamic Allocation of Virtual Machine Memory
The Dynamic Memory feature in Hyper-V in Windows Server 2008 R2 SP1 allows users to run Windows 7 SP1 and applications in a virtualized environment that can dynamically allocate memory for virtual machines. The Dynamic Memory feature allows IT administrators to specify starting value and a maximum value for virtual machine memory allocation. Because virtual machine memory can be dynamically allocated, the system resources are utilized more efficiently and are automatically adjusted based on the needs of each virtual machine.
To evaluate the Dynamic Memory feature of Hyper-V in Windows Server 2008 R2 SP1, you need to have the system requirements listed in the following table in addition to those in the “System Requirements” section in the “Getting Started” section, earlier in this guide.

Description and system resources
|
W2K2R2SP1
|
This is a physical computer that can be a standalone server or a member of a domain. This computer runs Windows Server 2008 R2 SP1 with the Hyper-V server role installed. The system resources of this computer are as follows:
Two or more processor cores running at 1.6 gigahertz (GHz) or faster
4 gigabytes (GBs) or more of physical memory
One disk partition that has 250 GB or more of available disk space.
|
WIN7-02
|
This is a virtual computer that can be a standalone computer or a member of a domain. This computer runs Windows 7 SP1 with the following system resources:
One or more virtual processors running at 1.6 gigahertz (GHz) or faster
1 GB or more of memory
One virtual hard disk that is 120 GB or larger.
| Evaluate Dynamic Memory User Experience
Evaluate how the Dynamic Memory feature in Hyper-V enhances user experience by performing the following steps:
Prepare Windows Server 2008 R2 SP1 for evaluating the Dynamic Memory feature in Hyper-V by installing the Hyper-V server role.
Install Windows 7 SP1 in a virtual machine running in Hyper-V.
Enable the Dynamic Memory feature in Hyper-V on the Windows 7 virtual machines.
Verify enhanced user experience for running additional programs in Windows 7 using Dynamic Memory.
Step 1: Prepare Windows Server 2008 R2 SP1 for Evaluating Dynamic Memory
Prepare the physical computer running Windows Server 2008 R2 SP1 for evaluating RemoteFX by performing the following steps:
Install Windows Server 2008 R2 SP1 on the computer.
Install the Hyper-V server role.
For more information about installing the Hyper-V server role, see “Installing Hyper-V” in the Hyper-V Planning and Deployment Guide available at http://www.microsoft.com/downloadS/details.aspx?FamilyID=5da4058e-72cc-4b8d-bbb1-5e16a136ef42&displaylang=en.
Step 2: Install and Configure Windows 7 SP1 in the Virtual Machine
Install Windows 7 SP1 in a virtual machine running in Hyper-V by using the default installation options. No additional software or device drivers are necessary in Windows 7 SP1 to evaluate the Dynamic Memory feature in Hyper-V.
Step 3: Enable Dynamic Memory Support on Windows 7 Virtual Machines
The Dynamic Memory feature must be configured for the Windows 7 virtual machine by performing the following steps on the computer running Windows Server 2008 R2 SP1:
Start Hyper-V Manager.
In Hyper-V Manager, select the first Windows 7 virtual machine and in the Actions pane click Settings.
In the navigation pane, under the Hardware section, click Memory.
In the properties pane, click Dynamic.
In Startup RAM, type 512.
In Maximum RAM, type 3192.
The Dynamic Memory settings are configured as show in the following figure.
Figure 2: Dynamic Memory configuration in virtual machine settings
In the virtual machine settings dialog box, click OK.
Step 4: Evaluate Dynamic Memory User Experience
To verify that Dynamic Memory is properly installed and configured and to evaluate the Dynamic Memory user experience, perform the following steps:
Connect to the virtual machine running Windows 7 SP1 using Hyper-V Manager.
Start the virtual machine running Windows 7 SP1.
Log on using an account that is a member of the local Administrators group on Windows 7 SP1.
Start Task Manager.
On the Performance tab, view the amount of memory currently available to Windows 7 SP1.
Tip: The total amount of available memory is displayed in Total under the Physical Memory (MB) section.
The amount of memory is close to the 512 MB value specified for Startup RAM in the virtual machine settings, as illustrated in the following figure.
Figure 5: Initial memory available to Windows 7
Start Calculator.
Start Paint.
Start WordPad.
Start Windows Explorer.
Start XPS Viewer.
Start Command Prompt.
Start Windows Media Player.
Start Windows Update.
Start Computer Management
Minimize all programs except Task Manager.
In Task Manager, on the Performance tab, view the amount of memory currently available to Windows 7 SP1.
Tip: The total amount of available memory is displayed in Total under the Physical Memory (MB) section.
The amount of memory available is now larger than the 512 MB value specified for Startup RAM in the virtual machine settings, as illustrated in the following figure.
Figure 5: Memory available to Windows 7 after running a few programs
In summary, the Dynamic Memory feature in Hyper-V in Windows Server 2008 R2 SP1 allows Windows 7 SP1 and applications running in virtual machines to dynamically allocate memory on demand. The starting amount of memory and the maximum amount of memory allocated to a virtual machine can be configured on a per virtual machine basis, allowing granular control over memory allocation for all virtual machines.
