Recently I want to try the new Windows Home Server 2011, but I don’t want to re-format my entire harddisk, therefore I have to give a try on the virtualization technology provided in Windows Server 2008 R2. Daniel Petri has written two articles (Preparation and Installation) explaining how to install and enable Hyper-V for Windows Server 2008 R2 , and in this article I’d like to make a summary for my own memory.
Hyper-V can only be enabled for CPUs that support Virtualization Technology and Execute Disable Bit. It might be necessary to change the BIOS settings in order to enable these options. As an example, the image below shows where to change them in a Dell PC:
Next, we install and enable Hyper-V through Server Manager. Please follow the steps below:
1. Open Server Manager click "Roles" and then "Add Roles".
5. The installation continues after the server is rebooted, and after about a minute, a message telling you that Hyper-V has installed successfully should pop up. Click "Close" to complete the wizard.
Create a new virtual machine
Now it is possible to start Hyper-V Manager to play with the virtual machines. Please follow the following steps to create a new virtual machine:
1. Start Hyper-V Manager either from Server Manager or through Start –> Administrative Tools menu:
3. A wizard should pop up, click "Next" on the Before You Begin window. Now you’ll see Specify Name and Location window, where you need to write the name of the virtual machine (Windows Server 2008 R2 in our example) and to specify the location where this virtual machine will be stored. After it’s done, click "Next" again:
5. Then we should get a window where we can choose what to do with the installation of the operating system. We can choose to install the OS later, install the OS now with either a physical disk or an ISO image, install the OS from a boot floppy disk, or install the OS from a network-based installation server:
Issues of Hyper-V
Be aware that once Hyper-V is enabled, it is not possible to hibernate the hosting computer. Furthermore, Hyper-V significantly decreases the performance of the graphics card, and it also seems to break DXVA H264 decoder with my HD5770.
