I am on the CTP for the VMWare Powershell Toolkit, and although I am unable to release any Information. I thought it would be a good idea to post some Powershell VMWare commands (old school) before they go live with the REAL Deal.
Hal from TechProsaic wrote a blog post here http://halr9000.com/article/445 about Using Plink to get Information about ESX and creating a custom object for the VM’s that the ESX host currently runs. I really liked the script, but I wanted a little more out of it. So I modified it (sorry Hal) and add some functionality. Below is a list of things it does.
Get Virtual Machines Running on ESX Host. Returns Custom Object
Provides a similar function to Get-Process from the ESX Host
Will Run a generic Command on the ESX Host
NOTE: At lines 16/31/62 I am having some issues with syntax highlight changing these to email addresses. Please make user the end up as $user @ $srv (no spaces)
