[Users] Ovirt 3.1 Issue

Hello anyone have any ideas about this error? I am setting up Ovirt 3.1 on CentOS 6.3, the nodes are also running CentOS6.3 and the engine appears to be ok but when I try and add a Node I get this error.. Failed to install Host Node1. Step: INSTALLER LIB; Details: deployUtil.py download failed. Pathname could not be resolved (verify computer/domain name).. -- Jonathan H Cox
