Thanks for the response, but my question was whether it's possible to start
libvirtd (and hence, activate the virtual networks "automatically") on 
boot, but
without dnsmasq being started along the way.

along with libvirtd. Why do you want to start it again by "net-start"
when it's already not started along with libvirtd? :-)
