"The goal is to identify the host that the guest is running on."
And what would you do with this information if you had it?
Bear in mind that the host identifier could change underneath you at any time.
Thanks,
Sean

What is your end goal here? I'm still not certain about your request.
You're asking for a value from the host, which is the box running ESX.
However, you're referring to the UUID, which is a unique value that
each VM has. Are you looking to uniquely identify the VM, or the host
that its running on?
I'm sorry for the confusion. The goal is to identify the host that the guest is
running on.
