This has been on my “to do” list for a while now – but I have finally got around to checking out the 5nine Manager for Hyper-V ( http://5nine.com/5nine-manager-for-hyper-v.aspx ). If you are unaware of this product – it is a management solution that is...

Before I get started today – I want to make one thing very clear: the content of this post is not officially supported by Microsoft.  Feel free to try it out – but if you hit problems do not go contacting Microsoft Product support – as this is unsupported...

Here is a problem that I was asked about a while ago: When I try to start a DOS application that switches to fullscreen in Windows XP Mode – it fails with an error that states “The video device failed to initialize for fullscreen mode.  Choose ‘Close...

If you are using Windows XP mode on an LCD display – you may notice that the font looks a little jagged.  The reason for this is simple.  ClearType is not enabled. While Windows Vista and Windows 7 both enable ClearType by default – Windows...

By default, Hyper-V will not let software inside of a virtual machine attempt to generate network traffic with a MAC address other than the address that Hyper-V has assigned to the virtual machine (known has MAC address spoofing ).  The reason why...

After the relatively trick “taking a snapshot” script – today’s snapshot script is quite easy. Listing the snapshots that a virtual machine has: # Prompt for the Hyper-V Server to use $HyperVServer = Read-Host "Specify...

Now that we know how to take a snapshot, and how to list snapshots – let’s start applying snapshots: # Function for handling WMI jobs / return values Function ProcessResult($result, $successString, $failureString) { ...

Here is a script that will allow you to delete a single snapshot from a Hyper-V virtual machine: # Function for handling WMI jobs / return values Function ProcessResult($result, $successString, $failureString) { #Return success...

A recent forum poster asked: How do I write a script that figures out how many virtual processors a virtual machine has, when it is offline (i.e. not running)? His question showed that he had made a classic mistake when working with the Hyper-V...

If you are like me, and obsessively ensure that all your virtual machines are kept up-to-date with the latest patches at all times, you may have wondered why your Windows XP mode virtual machine seems to be stuck with Internet Explorer 6. No matter how...

This week I am going to be sharing a bunch of scripts that show you how to interact with virtual machine snapshots in Hyper-V. And I am going to start off with the hardest one – taking a snapshot: # Function for handling WMI jobs / return...

A while ago I did a number of posts talking about the different controls that are available to you in regards to how Hyper-V schedules virtual machine processor resources ( Hyper-V CPU Scheduling–Part 1 , Hyper-V CPU Scheduling–Part 2 , Hyper...

Here is a dangerous script! Given a virtual machine name and a snapshot name, it will delete the specified snapshot *and* any snapshots underneath it in the snapshot tree that Hyper-V manager displays: # Function for handling WMI jobs / return...

I am running late on getting this post up – but a promise is a promise: We talked a lot about what is happening in Windows 8 at BUILD – and we also covered a lot of material about Hyper-V.  Luckily, all the sessions were recorded and can now be viewed...
