Hi,

this is the area that is somewhat actively worked on.

The leases file is located under 
/var/lib/libvirt/dnsmasq/default.leases, however I'd strongly recommend 
using libvirt API for that:

   virsh net-dhcp-leases default

BTW: it's not KVM's default network. The network is created and managed 
by libvirt ;-)
