Are you certain you have a dhcp server that is listening on the network
segment connected to your ovs bridge named "virbr0"? (note that you must
have created that bridge outside of libvirt, as a libvirt network can
only reference an already-existing OVS bridge; it doesn't know how to
create them. It also won't run a dhcp server for an ovs bridge, you'll
have to do that separately too).
