I got an interesting question from one of my co-authors of the PowerCLI Reference book. He was looking for a method to find the port used by a VM when connected to a portgroup on a dvSwitch.
Finding the answer to that question is not too difficult, once you know which property holds the value. But while writing and testing the script, I thought that this question would be a good opportunity to show several ways and methods that you have at your disposal in PowerCLI and PowerShell, to come to a solution.
Here it goes.

There was an interesting thread in the PowerCLI Community today. It raised the question how one could report on the current vCenter sessions, including the IP address or hostname from where the session was started.
Unfortunately the SessionManager doesn’t hold any information from where the session was started.
But there are other ways of finding that information. The UserLoginSessionEvent object has a property, called ipAddress, that has the information we’re after.
Btw if you are only interested in looking for idle sessions, independent from which host they were started, there is a great post, called List and Disconnect vCenter Sessions on the PowerCLI blog.
Update May 4th 2012: function updated to handle multiple vCenter connections.

In PowerCLI 5.0.1 a handy feature that showed the connected vSphere Servers in the title bar of the PowerCLI window was apparently removed.
In a PowerCLI Community thread some users found this a useful feature that they would like to have back.
I’m sure the PowerCLI Team will listen to their users and fix this problem in the coming PowerCLI version.
But while we are waiting for a new PowerCLI build that brings back the title bar text, you can fix this for yourself thanks to the proxy cmdlet feature.

For good security measures you should change the password of your root account on your ESX(i) servers on a regular basis. Instead of logging on to each and everyone of your ESX(I) servers, you can easily automate this process.
But what about the new ESX(i) hosts you will roll out in between root password changes and where you use a Host Profile to configure these new ESX(i) hosts ? Will you need to run a script after the deployment to change the root password ?
Turns out that you can easily update the root password in your Host Profile with the help of an SDK method.

As a belated Christmas present the new PowerCLI version 5.0.1 is available. This new build brings us the Cloud snapin. The availability of vCD cmdlets was already announced during VMworld 2011 and now the vCD cmdlets make their public appearance.
The first release of the Cloud snapin brings us primarily Get type cmdlets. But there is more, just as the Get-View cmdlet opened up access to the vSphere API, the new Get-CIView cmdlet, and the ExtensionData property, opens up access to all the vCD APIs.

The Invoke-VMScript cmdlet can be a very useful cmdlet, but sometimes it will fail against one or more of your VMs. And it is not always immediately clear why the Invoke-VMScript cmdlet will not work against that specific VM.
The cmdlet help contains a number of prerequisites, but how do you verify if all the prerequisites are fulfilled?
I decided to create a function that would verify the prerequisites, and that would, if requested, which of the prerequisites was missing.
