Transport - no network transfer available?

Hi,

I have a couple of VMware Vms that I am loading (very nicely, to be sure) in Fusion on the Mac. I was *thinking* about moving them to Parallels VMs. The Vms are beautifully connected to the Internet and host, but I get the message that a network transfer is not available. Enter the external hard drive. The Parallels USB driver blue screens the VM.
