There's no mention of shutting off the built-in DHCP server.
Maybe a specific ip address shuts it off.
qemu-system-i386 \
-nic user,model=ne2k_pci,ipv6=off,id=qemunic,net=10.0.2.2/24 \
...
Qemu works. The options aren't catastrophic.

I added this stanza to /e/n/i .
# An interface for subnet to qemu guest.
auto qemunic
allow-hotplug qemunic
iface qemunic inet static

netmask 255.255.255.0

The qemu -nic option above has "id=qemunic" and the stanza above
has qemunic. Nevertheless, host networking isn't happy with it.
" -nic tap, ..." might be a better bet than " -nic user, ...".
Other tips?
