That looks correct.

dpkg-reconfigure -p medium lxd

choose the appropriate input. For example, enable IPV4 NAT, choose
10.0.3.1 as address, etc. Your input would end up on
/etc/default/lxd-bridge. The default profile should work as-is (it
uses lxdbr0), no need to edit it.

Note that it does not perform verification, so for example, if you put
10.0.3.1 as bridge IP address but use 192.168.0.100 as DHCP start IP,
dnsmasq would simply won't start. Which might explain the problem you
experienced.
