How to tell if your CPU Supports SLAT

emma — Mon, 30 Jan 2012 16:12:05 +0000

SLAT-enabled processor is the requirement of Hyper-V RemoteFX feature which is introduced in Windows Server 2008 R2. It’s the requirement of Windows 8 client Hpyer-V feature as well.

For INTEL CPU models, following CPU models are SLAT-Capable

Server: E5500 or higher.
Desktop/Laptops: I3/I5/I7/I7-qm

There is a handy tool named CoreInfo from systeminternals that can check if your CPU is SLAT-Capable, it’s pretty easy to use:

Download from http://technet.microsoft.com/en-us/sysinternals/cc835722
Launch an elevated command prompt
Run “CoreInfo.exe -v”

If you see EPT Supports Intel extended page tables (SLAT) then you are good.

Hyper-v Tip: Use windows key without fullscreen

emma — Wed, 25 Jan 2012 17:03:07 +0000

When connect to a remote VM with hyper-v manager, I have to full screen to make Windows key. Personally I think Hyper-V should have a Windows key button in toolbar like "Ctrl+Alt+Delete" button.

Actually Hyper-v manager allows you to select where the Windows keys goes when you press it. Open up the Hyper-V Settings dialog from with the Hyper-V Manager and go to the keyboard setting, you will see 3 settings.

Use on the physical computer
Use on the virtual machine
Use on the virtual machine only when running full-screen

The default one is #3. Once you change it to #2, you will be able to use Windows key inside VM without *full-screen* it.

You will find this helpful if you are connecting to a VM has Windows 8 Metro UI enabled. Without a windows key it’s hard to exit Metro style app and go back to start screen.

How to turn on client hyper-v in Windows 8

emma — Wed, 25 Jan 2012 16:39:00 +0000

In Steven Sinofsky’s this blog – Bringing Hyper-V to “Windows 8”. He talks about that Windows 8 will support virtualization on the "client" OS. This is very helpful for developers as they typically have the need to setup additional test environment on their PC.

How to turn on client hyper-v in Windows 8

First, make sure your system meets the client hyper-v virtualization requirement, you have 64bit windows 8 OS and SLAT available on CPU.

Control Panel –> Programs
Turn Windows Features On or Off
Check Hyper-V, Click Ok

Note: If your system does not have the required virtualization support, the client Hyper-V feature will be greyed out. To check if your CPU is SLAT-capable, check this How to tell if your CPU Supports SLAT.

The other cool thing is you can turn hyper-v on even if you are booting from VHD. This behavior is same server Hyper-V in Windows Server 2008 R2.

TFS How to change the computer name or owner for a workspace

emma — Sat, 21 Jan 2012 14:34:40 +0000

The owner and computer name of the workspace are not editable in Visual Studio 2010. However, you might need it when you renamed your machine or your account is renamed. To do this, open a Visual Studio Command Prompt (2010) from program files, and cd to your workspace, then run following

Change the computer name for a workspace

tf workspaces /updateComputerName:<OldComputerName> /collection:

You need replace to your actual old computer name and to your actual TFS collection URL.

Using SCVMM 2012 Cmdlets in PowerShell

emma — Sun, 08 Jan 2012 11:39:23 +0000

SCVMM Cmdlets allow SCVMM admin/users to do everything they can do in SCVMM AdminConsole in windows PowerShell command line. In SCVMM 2008 R2, you can run following command in PowerShell to run SCVMM cmdlets.

Add-PSSnapin Microsoft.SystemCenter.VirtualMachineManager

But this does not work in SCVMM 2012 as SCVMM 2012 uses PowerShell module. For SCVMM 2012 now you need run following in PowerShell instead

Import-Module "C:\Program Files\Microsoft System Center 2012\Virtual Machine Manager\bin\psModules\virtualmachinemanager\virtualmachinemanager"

(This assumes that you have SCVMM 2012 installed on the default location C:\Program Files\Microsoft System Center 2012 )

The PowerShell cmdlets in SCVMM 2012 change a lot in SCVMM 2012, you can get a list of all SCVMM 2012 cmdlets by typing the following at the PowerShell command shell prompt

Get-Command -Module virtualmachinemanager -Type cmdlet

And you can run Get-Help on any of the cmdlets to get the syntax for that cmdlet.

Get-Help -detailed

Update: Microsoft has published the SCVMM 2012 cmdlets help to TechNet, check it out http://technet.microsoft.com/en-us/library/hh801697.aspx

SCVMM use BITS over https to deploy virtual machine to host server. To improve the performance of virtual machine deploy, you can disable encrypted file transfers for Host Group.

Open Virtual Machine Manager Administrator Console (aka SCVMM Console) on the Application Tier and connect to VMM Server
Click Host on the left side pane.
Right Click on All Host node, and select Properties.
Select the check-box “Allow unencrypted file transfers”

Note: if you use library server, you should set Allow unencrypted file transfers for every library servers.

The same can be done in following SCVMM PowerShell command

Set-VMHostGroup -VMHostGroup “All Hosts” -AllowUnencryptedTransfers $true
