There haven’t been any new blogs on Hyper-V.nu in the past weeks because of …. you know … an absolute dearth of time. It so happened that my other Hyper-V.nu colleagues had the same luxury problem in these economical challenging times.
So while I was doing a lot of other things which I will soon be able to talk about, I asked my colleague Sander Klaassen to fill in the gap and write a guest blog. Sander is also a Microsoft virtualization enthusiast and combines this with his broad other expertise.
Please welcome our guest blogger Sander Klaassen!
Over de last years I developed a script to quickly scan a customer’s IT environment. Recently I added a Hyper-V module which collects data from Hyper-V hosts and VM’s. I showed Hans Vredevoort the output and he asked me to write a blog about it. I was not sure to share the code, because it isn’t very clean, since I only occasionally work on it.
I created a VBScript and not a PowerShell script because I wanted to be able to run it without installing anything, and VBScript is part of windows since Windows 2000 so it’s always available.
This is also the reason why I made this script besides the regular Microsoft scan tools like ACT and MAP. They all need installation of components or even agents.
I modified the script for this blog, I changed the script by requesting input in a text file instead of Active Directory. This text file is a simple list of machine names:
Save it in the same directory as the VBScript with the name “machinelist.txt”
The script queries WMI name spaces of each machine and when it finds the Hyper-V role, it collects the following information:
Several hotfixes have been issued after the formal release of Windows Server 2008 R2 SP1. There was one particular hotfix in the making that we have really been waiting for. Many enthusiastic installers of SP1 in Hyper-V clusters with 3 or more nodes would face a problem with Cluster Validation. See the thread for more details.
We are glad that the hotfix has been made available today:
KB2531907 Validate SCSI Device Vital Product Data (VPD) test fails after you install Windows Server 2008 R2 SP1
A nice blog called Working Hard In IT by Didier van Hoye, describes all post SP1 hotfixes and can be found here.
Here are two RemoteFX hotfixes:
Now that SP1 is finished it is time to upgrade both our physical servers and virtual machines with Windows Server 2008 R2. Be aware that your Virtual Machines should be either upgraded to SP1 or upgraded with the latest Hyper-V Integrations if you want to use new features such as Dynamic Memory or RemoteFX.
Checking your Hyper-V Integration Version
One way of checking the IC version is by looking at the Driver version of the Microsoft Virtual Machine Bus Network Adapter in Device Manager
In a TechNet blog Michael Kleef announced that the number of VM’s per logical processor (LP) has been increased from 8:1 to 12:1, a 50% increase of VM density.
The increased ratio is supported if all guests run Windows 7. This is clearly aimed at Virtual Desktop Infrastructure (VDI) environments on Hyper-V R2. During the keynote of TechNet Europe 2010 we already heard increased VM density per host by at least 40%.
As from today the release candidate for SCVMM 2008 R2 SP1 is available from Microsoft Connect.
This version supports managing Hyper-V hosts with the new SP1 functionality: Dynamic Memory and RemoteFX.
Hopefully you can still find the SCVMM 2008 R2 SP1 RC section, because moments after I started downloading the package I could not find the dashboard entry for the product in Microsoft Connect

Just got news that SP1 Release Candidate is ready for download:
Today, Microsoft has made available a Release Candidate (RC) for Service Pack 1 for Windows Server 2008 R2 and Windows 7. SP1 includes both a roll-up of operating system updates and several new capabilities for Windows Server.
Microsoft RemoteFX introduces a new set of remote user experience capabilities that enable a media-rich user environment for virtual and session-based desktops. RemoteFX can be deployed to a range of thick and thin client devices, enabling cost-effective, local-like access to graphics-intensive applications. RemoteFX also supports a broad array of USB peripherals to improve the productivity of users of virtual desktops.
SP1 also includes Dynamic Memory, which enables servers running Hyper-V for server virtualization, to be more efficient in the use of memory. Dynamic Memory pools and distributes memory among the virtual machines running on a physical host, enabling higher consolidation ratios, increasing server utilization rates, and providing more flexible workload management. Furthermore, memory is dynamically added based on the demands of the current workloads and without service interruption.
Expect to see Service Pack 1 released in its final form during first quarter 2011 and whether you’re virtualizing servers or desktops, take a few minutes to learn more about Service Pack 1 here. You needn’t wait for SP1, however – you can join those already enjoying the benefits of Windows Server 2008 R2 by deploying today.
The official beta of Windows Server 2008 R2 (and W7) SP1 is now available:
So if you want to test Dynamic Memory and RemoteFX for superb graphical user experience in a virtual machine, here is your chance.
As Ben Armstrong pointed out in his blog that the full choice of supported operating systems will be available with the official version of SP1:
Supported with beta:
Additional support with final version of SP1:
