Thank you for this excellent suggestion! I upgraded to 4.1 and attempted to use this command, however it appears this opens up a new can of worms, and I am unable to complete automated install of Qubes Windows Tools. Details on this can be found in my new post at Qvm-create-windows-qube Qubes Windows Tools install hangs infinitely
Interestingly, the broken network adapter issue seems to be showing up again even with the qvm-create-windows-qube command. The XEN network adapter is visible and the Xen drivers were successfully installed (along with Tools) however I am unable to access the internet.
