I installed a new CentOS-6.3 kvm guest on a recently provisioned kvm host also running CentOS-6.3. This guest will not connect to the network and the host cannot connect to it via its public IP address. I had previously installed a guest system on thst same kvm host using the same ISO and that system connects to the network without problem.
I next created a third guest instance and this too does not connect with either the kvm host or the gateway.

It may turn out that I have inadvertently some configuration value set incorrectly but at the moment it seems to me to be a problem with virt-manager. Basically, new guest instances are having this put into their definition file by virt-manager:
<interface type='network'> <mac address='52:54:00:6c:35:1a'/> <source network='default'/>
when it should be:
<interface type='bridge'> <mac address='52:54:00:6c:35:1a'/> <source bridge='br0'/>
