System Center 2012 – Virtual Machine Manager

This year Microsoft release a new palette System Center 2012 products. Virtual Machine Manager is probably the System Center 2012 product with the most significant updates.
There are a lots of updates in Virtual Machine Manager 2012 to mention them all, but here are few of the most important enhancements.

Virtual Machine Manager 2012 – New features

Virtual Machine Manager 2012 new features can be divided in four segments as shown on picture below:

1

1. Infrastructure enhancements

Highly Available VMM server. As Virtual Machine Manager is core of management infrastructure for virtual environment it is really important for this infrastructure to be highly available in todays big datacenters.

2. Fabric Management

Virtual Machine Manager 2012 can now manage even more hypervisors: Hyper-V, VMWare and Citrix XenServer. Also it can integrate with remote management such as iLO and SMASH. One interesting thing here is also ability for bare metal provisioning meaning that with Virtual Machine Manager 2012 you can provision Hyper-V even on bare metal computers without much manual work. Cluster creation with storage provisioning is also one of the interesting new features. Regarding the network management enhancements, Virtual Machine Manager 2012 can now integrate with load balancers. Besides that now you can also assign IP and MAC from pools. Dynamic Optimization and new Power Management features are also important updates as described in Cool Features.

3. Cloud Management

Virtual Machine Manager can now abstract server, network and storage resources into private clouds, delegate access to private clouds with control of capacity, capabilities and user quotas. Also now it is rather easy to enable self-service usage for application administrator to author, deploy, manage and decommission applications in the private cloud.

4. Service Management

With Virtual Machine Manager 2012 you can now define service templates to create sets of connected virtual machines, OS images and application packages. Maybe the most important feature in service management is ability to leverage great and power full technologies like Server Application Virtualization (Server App-V).

Virtual Machine Manager 2012 – Cool Features

1. Support for cloud, fabric, and services management

Virtual Machine Manager 2012 has moved into the cloud and services management space. VMM 2012 adds cloud support, where the Cloud is defined as a collection of resources that can be assigned to users or groups. The cloud is composed of a Fabric, which is the underlying IT infrastructure, and Services, which are collections of virtual machines (VM’s) that perform a given task.

2. Dynamic Optimization

The addition of Dynamic Optimization is Microsoft’s answer to VMware’s Distributed Resource Scheduler. Dynamic Optimization provides cluster-level workload balancing for VM’s. Like the older VMM Performance and Resource Optimization (PRO) feature, Dynamic Optimization lets VMM analyze workloads and dynamically move VM’s to different hosts by using Live Migration. Unlike PRO, Dynamic Optimization doesn’t require Operations Manager. The PRO feature will still be available in Virtual Machine Manager 2012.

3. Power Optimization

A feature closely related to Dynamic Optimization is the ability to optimize the placement of VM’s to minimize power consumption. Power Optimization in Virtual Machine Manager 2012 can use Live Migration to consolidate running VM’s onto fewer virtualization hosts, then power down the unneeded hosts.

4. Enhanced placement rules

Intelligent Placement enabled the previous version of Virtual Machine Manager to evaluate host capacity and suggest the most appropriate virtualization hosts for deployment. Virtual Machine Manager 2012 extends this capability with over 100 virtual machine placement checks and also adds support for custom placement rules. In addition, Virtual Machine Manager 2012 supports multiple virtual machine deployments as services.

5. Upgrade support

Nice feature in Virtual Machine Manager 2012 is the ability to perform in-place upgrades from existing Virtual Machine Manager 2008 R2 with SP1 installations. Customers will be able to upgrade from Virtual Machine Manager 2008 R2 with SP1 to the Virtual Machine Manager 2012 RC, and then upgrade from the Virtual Machine Manager 2012 RC to the final RTM release of Virtual Machine Manager 2012.

6. Bare-metal Hyper-V provisioning

Another new feature in Virtual Machine Manager 2012 is the ability to perform bare-metal provisioning of Hyper-V servers. This feature lets Virtual Machine Manager create new Hyper-V hosts on bare-metal systems by using predefined templates.
Virtual Machine Manager 2012 is also integrated with remote management technologies such as iLO (HP’s Integrated Lights Out) and SMASH (Systems Management Architecture for Server Hardware).

7. Manage multiple hypervisors

Virtual Machine Manager 2012 is able to manage all the major virtualization platforms. In Virtual Machine Manager 2008 R2, Microsoft added the ability to manage VMware’s vSphere Server via vCenter Server. With the release of Virtual Machine Manager 2012, Microsoft is adding the ability to manage Citrix XenServer. Microsoft Virtual Server 2005 and ESX 3.0 is not supported.

8. Cluster awareness

At the previous version of Virtual Machine Manager we did not have a cluster-aware application. Virtual Machine Manager 2012 is cluster aware and can be installed on a Windows Server 2008 R2 failover cluster, giving Virtual Machine Manager 2012 improved availability and the ability to fail over to a backup node in the event of a server failure.

9. PowerShell 2.0

Virtual Machine Manager provides PowerShell cmdlets for command-shell management, and actions in the Virtual Machine Manager console can be used as a basis for generating PowerShell management scripts. Virtual Machine Manager 2012 enhances this management capability with full support for PowerShell 2.0.

There are much more enhancements in System Center 2012-Virtual Machine Manager. Check them on technet and start your journey to the Cloud.

I can’t wait RTM, this would be/is a great product from Microsoft System Center team Winking smile.

Prepare Hyper-V virtual machine image for cloning

In one of my previous posts I explained how to Clone a virtual machine with the Virtual Machine Manager, but before Clone our virtual machine we need prepare the virtual machine for cloning.

As you probably know by now, Microsoft-based operating systems use SIDs (Security IDs) that are generated as part of the initial setup of Windows. If you have more than one computer with the same SID, this could cause problems, and cloning a computer (either physical or virtual) without re-generating this SID can cause SID duplication.

Due to the above, we need to prepare virtual machine image for cloning.
This guide assumes that you’ve got some sort of virtualization infrastructure in place. In my case this is a Microsoft Hyper-V. It also assumes that you’ve got some sort of virtualization management tool like System Center Virtual Machine Manager.

In addition, it’s important that you have a basic knowledge about how to set up and run your virtualization product, that you are knowledgeable about setting up virtual machines, and about the proper procedure to install and configure a Windows-based operating system on these virtual machines.

Also, , this guide assumes that you’re knowledgeable about the proper procedures needed to be taken prior to creating a virtual machine clone, how to use SYSPREP (the system preparation tool from Microsoft), and how to create proper answer files for the preparation procedure.

In this post I ‘ll describe how to prepare virtual machine images for Windows Server 2008 R2 and Windows 7.  In Windows Server 2008 R2 and Windows 7 the SYSPREP tool is already included in the operating system, therefore there’s no need to download it like for Windows XP.
To create the proper answer file under Windows Server 2008 R2, Windows 7, you need to either manually edit an existing answer file, or create one for your needs.
To create an answer file for Windows Server 2008 R2 or Windows 7, you must use the tools available in the Windows Automated Installation Kit (AIK) and you can download here.

Preparing the System for Cloning

Prior to cloning the virtual machine there are several steps that you need accomplish. This is not a requirement but is recommended.

  • Log on to the computer as an administrator.
  • Install and customize applications.
  • Customize the Default User profile.
  • Update Windows and other software components.
  • Clean temporary files.
  • Defragment the disk, and compact the VHD file.

Create the UNATTEND.xml Answer File for Windows Server 2008 or Windows 7

Unattended Windows Setup answer file in Windows Server 2008 R2 and Windows 7, is an XML file typically called Unattend.xml. This is the answer file for Windows Setup that is created by using Windows System Image Manager (Windows SIM). The answer file enables the configuration of default Windows settings, as well as the addition of drivers, software updates, and other applications.
The unattended Windows Setup answer file in Windows Server 2008 R2 and Windows 7 needs to be specified during the running of SYSPREP. To do so, run the SYSPREP tool with the /unattend:filename option.

If you wish to manually configure the Windows settings after SYSPREP, run SYSPREP from the C:\Windows\System32\sysprep folder.

1

Make sure you do NOT FORGET to select the “Generalize” option if you need to change the computer’s SID. It seems that this version will NOT change the SID unless you pick that option.

2

Sysprep is working.

3

When the process is complete the virtual machine will shut down.

OK, our VM is prepared for Cloning and if you want to know how to Clone VM with System Center Virtual Machine Manager read my previous post about that.

After starting cloned machine, you will be prompted to configure few settings like the user name, computer name, language and some other settings.

4

I need to mention, creating an answer file will greatly ease this process, and the entire process will automatically run.

Folks that’s it!

Clone Virtual Machine with Virtual Machine Manager

Today I had to Clone a virtual machine in my production environment and I would like to explain how it works. This is a simple procedure with few steps and the whole procedure will be explained as always with many pictures. Before the cloning of virtual machine image you have to prepare the System for Cloning.

As you probably know by now, Microsoft-based operating systems use SIDs (Security IDs) that are generated as part of the initial setup of Windows. If you have more than one computer with the same SID, this could cause problems, and cloning a computer (either physical or virtual) without re-generating this SID can cause SID duplication.

How to prepare the system for cloning I will write in another post.

Step 1.

You must first shutdown virtual machine which you want to Clone. When your VM is turned off, right click on VM and choose Clone.

1

At the second step choose new name for your new virtual machine.

2

On the Configure Hardware field if you need the same hardware configuration like previous VM leave hardware configuration by default or edit what you need.

3

At the next step you need to choose where you want to deploy the virtual machine. I chose “Place the virtual machine on a host”

4

At the next screen I chose host on which was located the previous virtual machine.

5

Select virtual machine path…

6

Specify virtual network…

7

At the end review the virtual machine settings. If you want to start cloned virtual machine immediately check mark “Start the virtual machine after deploying it on the host”  and click Create.

8

The process started.

9

When the process is finished we have two of the same virtual machines whit the same settings.

10

Before you turn on both virtual machines you need to rename the new one. How to do that, especially if your vm’s are in the domain,  I‘ll describe this in my next post.

Until then have a nice week!
