If you do this, do it properly and warn if any qemu vlans have a single dev=

You are mistaken. -net user does not imply -net nic.
I suspect you're confusing it with the old network options.

=2Dnet creates devices and attaches them to the virtual network, whether th=

emulated devices on the host, or devices for communication with the "real"=
