I believe the problem is caused by libvirt not shutting down dnsmasq.
I seem to have had a previous configuration, that I had deleted, which used the
same network. Even though I had restarted libvirt-bin in between, dnsmasq
wouldn't be killed, so it somehow was refusing to start with same network
again, AFAICT.
Shutting down dnsmasq when a network is stopped / removed and when libvirt
daemon is shut down would fix the issue, IMHO.
Hope this helps.
