but it says "<device-vm-name>" on the detatch, where the attach is
"<file-vm-name>"... they are different...
So naturally, I assumed that fince it didn't say anything about
"<file-vm-name>" that since I turned the file into a device on the guest, that
the guest was the device-vm.
I merely looked at it the way that it said it's things.
But now I know better.
