Thank you for the answer, but... How would I do that on Windows?
I tried installing the "tap" driver from
https://openvpn.net/index.php/download/community-downloads.html (NDIS6, since I
use Windows Server 2008 R2 == Windows 7), and then I assigned it an IP
(192.168.200.1/24), but if I then try to start the VM with
"-netdev" "tap,id=user.0" "-device" "e1000,netdev=user.0 "
Qemu just fails to start the VM, and quits with no error message on screen. I
even tried to rename the tap adapter to "br0", to be closer to the examples on
the linked page, but the same thing happens.
The docs from the Qemu sources don't seem to provide any more hints either.

You can use a bridged network setup, so your guest and host have their own IPs.
