A couple of weeks ago VMware released a new fling called “PowerActions for vSphere Web Client”. What it does, is to integrate PowerCLI, which means that you can now run PowerCLi/PowerShell scripts directly from the Web Client.
All you need is a server where you install the PowerCLI version that matches your current VMware vSphere version. Then you run the PowerActions executable, and you’re good to go.
