Hi,
Seems the communication with the host is slow and you get a timeout error.
Is there a chance you opened the SetupNetwoks dialog while installing the host (it may slow down the host since it queries the host for lldp information)?
Please try to re-install (or remove and re-add) the host (don't open the setup network dialog during the installation).
More technically, there is a bug in the code -
Collecting and persisting the data from the host is done inside a transaction.
Only the persisting should be done in a transaction.
According to the attached log seems the collection of the data from the host finished successfully (was slow, but finished without a timeout), but the persistence of the data fails since during the persistence the transaction reached to the timeout.
Can you please file a bug in the bugzilla and attach the relevant logs (engine.log, server.log and vdsm.log)
Thanks.
Alona.
