rhev-guest-agent doesn't connect to rhev-m

Ive got a new rhel6.4 vm installed with the rhev guest agent, but nothing (no IP, cpu usage etc) appears in the rhev-m...

# yum list installed |grep rhev

rhevm-guest-agent.x86_64           1.0.5-8.el6ev             @rhel-6-server-rhev-agent-rpms

# service ovirt-guest-agent status

ovirt-guest-agent (pid  1845) is running...# service ovirt-guest-agent status

Can anyone point me in the right direction to diagnose?
