Hi Stefan,
I have gotten you example to list the UUID's of all VM's successfully
but im having issues trying to get information on specific VM's. Im
sure its something im overlooking but when I run the code below I get
the following errors returned:
EPERMDENIED
Session Invalid
My code is below. Thanks for your help.
