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

[Mohsen Saeedi]

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
