Then you must be checking the “Edit virtual hardware (Experimental)” box when you are cloning… DON’T DO THAT! Leave it unchecked and you won’t have any problems…

  1. Yep – I can verify this one… it’s an irritating little bug, but nothing that can’t be overcome.

    @Brian Goh: I think it may have something to do with the number of VMs in a given farm. Back when I only had a handful, this wouldn’t really show up. OTOH, now that the average farm in my care has around 200+ VMs in it, it’s almost a guarantee that checking that little box will bring some sort of headache.
