How to set vmGuestOsIdentifier within of a scriptable task?

Hello,

i am struggling with the fine-tuning of my workflow fo VM creation.

As you probably know, when creating a VM, the guestOS needs to be set.

At first, i've set the input type to vmGuestOsIdentifier, but this didn't look so nice, because the IDs aren't exactly like the original OS-names (e.g. "winLonghorn" is "Windows Server 2008 32-bit").

So i've created a list of all the OS names, that are being used on our VMs, set the input type to string and set the list as a list of predefined elements.

Nonetheless i still need to have a variable of the type vmGuestOsIdentifier which needs to be set, but now within a scriptable task.

And that's what i'm struggling with.

How can i set the the vmGuestOsIdentifier within a scriptable task?

Thanks and

Regards

Andreas
