Comment 1 for bug 1677325

I don't think we'll be able to get tagging in for 2.2. To create tags, you need to use an entirely separate API/SDK: http://pubs.vmware.com/vsphere-65/index.jsp#com.vmware.vapi.progguide.doc/GUID-80558230-E905-46D3-BFAA-E99061835F3F.html There is currently no vSphere Automation SDK for Go.

What I will look at doing is putting VMs into folders, so they're organised by controller and model.
