You can create a custom property by writing a script and providing a name for the property. The script evaluates when the custom property is called for the first time.

Prerequisites

Verify that you are connected to a vCenter Server system.

Procedure

  1. Create a new custom property named NameOfHost that stores the name of the host on which a virtual machine resides.
    New-VIProperty -Name NameOfHost -ObjectType VirtualMachine -Value { return $args[0].VMHost.Name }
  2. View the NameOfHost properties of the available virtual machines.
    Get-VM | select Name, NameOfHost | Format-Table -AutoSize

Results

You created a custom script property named NameOfHost for VirtualMachine objects.
