Soon after I started using kvm and created guests with bridged network, I asked the same question as yours. I have not been able to find a clear answer to date. If I'm not mistaken, there is no easy solution as you suspected. The host has no knowledge of the guests' IPs because an outside DHCP server (in my case at home, it is a router/cable modem) provides the IP addresses. So, I've been using the "console" method.
Your router/cablemodem most likely has a web interface where you can find a log and a mapping of MAC addresses to the IP addresses it has given out. You might even be able to configure it to syslog to your centos box. You should also be able to see the DHCP traffic activity by running tcpdump or wireshark on the bridged host physical interface as the guest starts.
Sure, I can retrieve the info from my cable modem. I also tried wireshark. I then decided looking at the console was much "quicker" for me. But if I'm in a situation where the guests are constantly created and there is a need for semi-automatic retrieval of guest's IPs, I would spend some time for that.
