Sapien have released a FREE thumb drive app which is stored as a single EXE, this editor allows you to edit your scripts in the code highlighted environment we all love, step away from notepad and into the future.

This app also has code highlighting features for the following scripting languages:

  • BScript

VI Toolkit Presentation

imageThis week I gave a presentation to the UK PowerShell User Group at the Microsoft HQ in the UK, this was also available over live meeting and seemed to go quite well, despite the issues with the projectors, wifi, sound and rooms we were in.

For those people who couldn’t make the live meeting or the UK PowerShell User Group I have uploaded my slide deck for you to have a look through.

Download the slides here in PDF format… http://virtu-al.net/Downloads/VMwareVIToolkitPSUKUG27-03-09.pdf

My Presentation followed a nice insight into the 2008 Active Directory cmdlets that are being released by Microsoft, Jonathan Medd gave a great comparison of this and the Quest tools and also showed us a nice demo of the new Recycle bin feature in 2008 Active Directory.


These were both recorded and presented over Live Meeting, I will include a link so that you can watch them as soon as it is available.

VI Toolkit One-Liner: VM Guest Disk Sizes

A Simple One-liner today but it shows you how to add information along the pipe line to enable new properties which can be formed using other cmdlets or simple math statements on existing properties:

This one-liner will give you the VM disk or partition sizes for each of your VMs:

ForEach ($VM in Get-VM ){($VM.Extensiondata.Guest.Disk | Select @{N="Name";E={$VM.Name}},DiskPath, @{N="Capacity(MB)";E={[math]::Round($_.Capacity/ 1MB)}}, @{N="Free Space(MB)";E={[math]::Round($_.FreeSpace / 1MB)}}, @{N="Free Space %";E={[math]::Round(((100* ($_.FreeSpace))/ ($_.Capacity)),0)}})}

VI Toolkit One Liner: Correct HAL ?

I have just re-worked an old script which I created to check each VM to ensure they are using the correct HAL based on the amount of processors they have installed, as it turns out I managed to get this into a nice one-liner:

Or to break it down so it fits on my blog…



VI Toolkit One Liner: Who’s busy ?

Most of my work with the VI Toolkit has been scripts so far, well the work that I  have added to this blog anyway, I use one-liner’s on a daily basis to make my job easier.

It was suggested to me that I should add some one-liners to my blog as I’m going to be busy over the next couple of weeks so I had a quick tinker.

This one-liner is quite a simple but long one-liner just to get started:

View the top 10 VM’s which have been using memory for the last 48 Hours:

PowerGUI VMware PowerPack 2.1.5 released


Scott and Kirk have done it again, they are really kicking out the updates to this powerpack recently and this one adds some great features:

1. As you can see by the image, they have greatly improved the icons making a great visual experience.

2. You may notice a new Action on the menu… Generate vDiagram


Yes that’s right, Kirk has taken my Visio script, torn it up, threw it out and come up with something completely amazing.

VI Toolkit Lab @ VMWorld

Whilst at VMWorld I managed to sit in on the very popular VI toolkit Lab, this was one of around 10 labs which were running during the day and people could go up and run through some testing on a pre-built lab environment all for themselves.

This gives people a great opportunity to play and mess with things that they may not get a chance to do in there normal line of work.

Setting MMU for your VMs

I was asked by my friend Duncan if it was easy enough to set the Memory Management Unit (MMU) for each of his VM’s.  Read his post here for more information on what he was working on.

He was about to set this by hand for 50+ VM’s which would take a while, so with the power of the VI Toolkit he can now take it easy whilst PowerShell does the hard work:

For one VM:
Get-VM -Name "MyVM" | Get-View | foreach {
    $spec = New-Object VMware.Vim.VirtualMachineConfigSpec
    $spec.flags = New-Object VMware.Vim.VirtualMachineFlagInfo
    $spec.flags.VirtualMMuUsage = "on"
    $taskMoRef = $_.ReconfigVM_Task($spec)
For all VMs you could use:
Get-VM | Get-View | foreach {
    $spec = New-Object VMware.Vim.VirtualMachineConfigSpec
    $spec.flags = New-Object VMware.Vim.VirtualMachineFlagInfo
    $spec.flags.VirtualMMuUsage = "on"
    $taskMoRef = $_.ReconfigVM_Task($spec)
Or for each of the VMs in a cluster:
Get-Cluster "MyCluster" | Get-VM | Get-View | foreach {
    $spec = New-Object VMware.Vim.VirtualMachineConfigSpec
    $spec.flags = New-Object VMware.Vim.VirtualMachineFlagInfo
    $spec.flags.VirtualMMuUsage = "on"
    $taskMoRef = $_.ReconfigVM_Task($spec)

To list each of the VM’s and their current MMU setting use this one-liner:

Get-VM | Get-View | ForEach {Write "$($_.Name) - $($_.Config.Flags.VirtualMmuUsage)"}

The VESI is on its way

Whilst at VMworld Europe 2009 I managed to get a sneak preview of the VESI, if you are unsure what this is then please check my previous post here.   Judging by the interest of the Vizioncore stand and the fact that Scott Herold was looking rather tired at the end of each day I am sure this product is going to AMAZING.

I managed to capture a few sneaky pics of the vDiagram portion of the app and let me tell you, if you liked my original script then you are in for a treat when they release this app, as you can see below they have added more features, nicer shapes and a whole can of kick ass in the process.

VI Toolkit voted Number 1

In a recent VMTN Round table podcast we were asked what our predictions would be for 2009, mine was “Automation of VMware Products”,  after visiting VMWorld Europe 2009 in Cannes it would seam that my prediction was coming true.

Whilst there I attended ‘TA01 – Managing VMware With PowerShell’ presented by Carter Shanklin (VI Toolkit Product Manager), one of the developer of the VI toolkit and also Dennis Zimmer (CTO of Icomasoft).
