[Users] Installing Host - action is taking longer than allowed by configuration

Hi I Installed ovirt 3.1 all in one package under centos 6.3 . but when i trying to install localhost as virtualization node (I have one server with local storage) i got a error: The required action is taking longer than allowed by configuration. I know the reason for it. i have very slow connection. I think ovirt clean yum metadata and try to get metadata again. but my internet connection is very slow (about 64Kb/s) and takes a lot of time to finish. how can i increase the allowed time by configuration or some change on postgresql database.? Thanks
