It's feature. In fact, when your domains are using the default network
you want to have dnsmasq running as it is (beside others) dhcp server
for them. Even when libvirtd is down (domains tend to regain DHCP record
from time to time).

If you don't want to use the default network, you can just unset autostart:

    virsh net-autostart --disable default
