After you designate a host for virtual machines in System Center Essentials 2010, you can select the host when you create a new virtual machine. You will not be able to create a new virtual machine until you have first designated a server as a host for virtual machines.

When you select a host for virtual machines, you can choose between servers that use either Hyper-V or Virtual Server technology. We recommend that you choose hosts that use Hyper-V. Core feature set differences between these technologies include support for up to 64 guest virtual machines, symmetric multiprocessing (SMP) support, performance improvements, 64-bit guest and host support, and host clustering. Hyper-V also uses several new networking technologies in Windows Server 2008 R2 to improve overall virtual machine networking performance. The technology type for host servers is displayed in Essentials 2010 when you perform tasks such as creating new virtual machines, converting physical machines to virtual machines, importing virtual machines, or migrating virtual machines to a new host.

To select a host when creating new virtual machines
  1. In the Essentials console, click the Computers button, click Computer Groups, and then click All Virtual Machines.

  2. In the Tasks pane, click New Virtual Machine.

    You must first designate a host server for virtualization management in order to create a virtual machine from a template. Read Designating a Host for Virtual Machines if this step has not yet been completed.
  3. In the New Virtual Machine wizard, select the template to use. Click the Change Properties button if you want to change any of the template properties before the virtual machine is created, and then click Next.

  4. On the Select a Host page, select the server you want to use as a host for the new virtual machine, and then click Next.

  5. Complete the New Virtual Machine wizard. A progress bar will be displayed while Essentials creates the virtual machine. After the virtual machine is created, Essentials will automatically start the virtual machine and connect you to it.
