Are you sure that the DHCP service is coming from QEMU? As far as I
know, QEMU only provides DHCP for the "-netdev user" interfaces, but not
for tap / bridge.

Are you using libvirt or something similar on top of QEMU? If so, the
DHCP service might be provided by that layer instead, see for example:
