I think you've got something odd going on.... I'm using a bridged setup 
with libvirt and although I do have a dnsmasq running it is for the 
private network defined in libvirt (which I'm not using) and it is only 
listing on that private network's address.

So when I list networks I just have the default one:

virsh # net-list
Name                 State      Autostart
default              active     yes

and it is defined over a private address range:

virsh # net-dumpxml default
   <forward mode='nat'/>
   <bridge name='virbr0' stp='on' delay='0' />
   <mac address='52:54:00:37:0B:C2'/>
   <ip address='' netmask=''>
       <range start='' end='' />

and that is what lsof shows dnsmasq as listening on:

dnsmasq 2229 nobody    6u  IPv4              23692      0t0       TCP (LISTEN)

Though like I say, I don't actually use that as I have br0 setup as a 
bridge to my ethernet card and use bridged networking with that instead.
