Therefore, you must follow the following four steps for basic configuration before you apply the update: 1. Record the static IP configuration: If the virtual machine is set up to use a static IP address, write it down. As part of the upgrade process, the virtual machine will need to be re-created using the old virtual hard disk VHD. Additionally, because virtual machines will need to be re-created, actively using a snapshot when the RTM update is applied can possibly lead to data loss. Record virtual network names: Any virtual networks that were created under the beta of Hyper-V will need to be re-created.
If you want to maintain the same names after the update is applied, record the name of each virtual network so it can be re-created after updating. Re-create virtual networks: Create any custom virtual networks that were present in the earlier version of Hyper-V. Re-create virtual machines: If virtual machines were running on the host before you updated to the RTM version of Hyper-V, they will need to be re-created. Update integration components: The Hyper-V RTM update includes new integration components that need to be updated in the virtual machine.

You can find information about how to apply the updated integration components in Chapter 4. There are three ways to do it. By performing an in-place upgrade, your virtual machines will be preserved in the Hyper-V Manager and your settings will be maintained. You can check to see whether KB is installed.

If KB is not installed, then the upgrade is blocked. However, before exporting, make sure that the virtual machine is shut down and that any snapshots are merged. After the host operating system has been upgraded successfully, make sure Integration Services is updated in the virtual machine. For more information on Integration Services, refer to Chapter 4. A full installation of Windows Server includes the full user interface. This is the only installation option that has been present for Windows Server until now. Windows Server Core uses the same device drivers, has the same kernel installed on disk, and behaves the same way as a full installation of Windows Server.
The main difference is that the graphical subsystem of Windows, as well as other products and services, are absent from a Server Core installation. Additionally, items such as Internet Explorer and Windows Mail have been removed. With Windows Server R2, the. By including the. NET framework are now available in a Core installation. No longer will your Windows Servers need updates for Internet Explorer, Outlook, or other little-used components. Systems running Windows Server Core can see up to 40 percent fewer patches compared to systems running Windows Server This memory savings can be used for more or larger virtual machines.
Many of the Windows administration tools that are accessed through the Microsoft Management Console MMC can be configured to administer other computers in either a workgroup or a domain setting. Not all administrators prefer that approach, however. To move to a full installation of Windows Server , you must reinstall the system.
Resolving The Problem
Some vendors have provided command-line functionality, but not all have—check with the hardware vendor for the latest drivers. This allows administrators to perform the same tasks using a common tool set. Administrators can connect to the Server Core system from another Windows system for administrative purposes. The user experience is identical—the user logging in from the remote system will only get a command prompt in their Remote Desktop session.
It provides a common method for systems to access and exchange management information across the entire IT infrastructure.
To add Windows Remote Shell, follow these steps: 1. You can write scripts in a variety of different languages—Jscript, VBScript, and so on providing the scripting engine for that language is installed. A Windows Server Core installation can also be administered from a full installation of Windows Server.
Installation Considerations and Requirements As we detailed in the previous section, there are pros and cons to running Windows Server Core. Before you implement Windows Server Core, system planners should ensure that their tools and scripts work as expected in the Windows Server Core environment and that administrators are comfortable in the command-line environment.
Additionally, you should confirm system management and antivirus tool functionality. The main difference is in the amount of disk space required. Because Windows Server Core has fewer binaries on disk, it requires less disk space. Memory MB minimum. Maximum supported memory depends on edition. Disk 20 GB space minimum, 40 GB or more recommended.
Select the version for which the system is licensed in the Server Core installation—this will install Windows Server in the Server Core configuration. Select the volume for installation, and the installer automatically proceeds and reboots a few times. In the full server install only, you must set the password for the administrator as the initial step. Doing the Initial Configuration Because Windows Server Core has no graphical elements, you need to use the command line to configure the system.follow site

You can find additional information about configuration at the Windows Server site: www. Specifically, the netsh command-line tool provides the functionality to set the IP addresses on the NIC, among other things. To set the management NIC to use a static IP address, run the following commands: Netsh interface ipv4 show interfaces c Run the following command: Netdom.
To enable Remote Administration, run the following command: Cscript. The released media for Windows Server includes the beta version of Hyper-V and must be updated. Browse to where the file is located, and run it. For the Hyper-V final update, the filename is Windows6.
After the update succeeds, you must restart the system. To install the role, follow these steps: 1.

After the system starts up, log in. The system installs all the necessary files for Hyper-V. Click Yes to reboot the system. After the reboot, the system is ready to run virtual machines. From another system, use the Hyper-V Manager to connect as the local administrator account on the Server Core host. Before you create a virtual machine, you must create virtual networks. You can now use the system to run virtualization workloads on top of a Windows Server Core system. Summary In this chapter, we detailed how administrators can lay the groundwork for implementing virtualization in your environment.
By having Hyper-V as a role of Windows Server , Microsoft has provided an easy deployment scenario, allowing users to add the virtualization layer to Windows. For production servers where the host is running only the Hyper-V role, Windows Server Core is easily the best choice. The Hyper-V Manager is a powerful management interface that provides easy-to-use wizards for tasks such as new virtual machine creation, shows an all-up view of all virtual machines on a host, and has multiple host management built in.
By default, only one host is listed: the local host on which the MMC is running. After typing the host name in the Another Computer text box, you can perform all Hyper-V administrative tasks against that system. This section also lists the status of all the VMs, including the state running, off, saved, and so on , central processing unit CPU utilization, the amount of time the VM has been running, and operations that are currently taking place against the VM. The snapshot functionality is one of the new features in Hyper-V. A snapshot is a point-in-time representation of a VM.
As an administrator, you can move back and forth between snapshots and easily perform tasks such as resetting a test environment. On the right is a list of actions that you can take against the selected host. If you create a VM and select it here, more options appear below; these are actions you can take against the selected VM and are dependent on the state of the VM.
This enables you to remotely configure and control a Hyper-V host. Select Features, and then select Add Features. Make sure you select the correct package to download—packages for both x86 and x64 architectures are available. It will walk you through the initial configuration of the VM. Click Next to continue. One common gotcha is assigning the same name to two different VMs.
These files include the. When a VM is powered on, both. This file ensures that, in case of a system shutdown, the VM can be saved. When the state of the VM is saved, the. One common reason to change the default location of the VM is so you can create a highly available VM. On the Assign Memory page, the memory assigned to the VM is set.
