You can disable listening on the dhcp port by simply not having a <dhcp>
section in the network definition. The DNS service is always present if
you define an IP address for the network though.

The confusion comes when someone tries to start up their own dnsmasq,
which also wants to run its own DNS service, on the same bridge - the
entire thing fails. If you run a pure dhcp server though, it should work
with no problems.

I have plans to disable even the dns server if someone specifies "<dns
enable='no'/>" in their network config (we can't do it based on the
absence of a <dns> element, since that has never before meant "no dns"),
but that's not implemented yet.
