I guess that was a little unclear. There are various host columns. One on the networks table, one on the floating ops table one on the fixed ops table and one on the instances table. You should check all of these for the old hostname and change them to the new one. On Aug 11, 2011 5:41 AM, "Mercadolibre CloudBuilders" < question167613@answers.launchpad.net> wrote:

Mercadolibre CloudBuilders is still having a problem: Hi Vish!

Since is not an option for us to change the hostname of the new controller, cause that machine WAS a compute and is running a lot of machines, i want to understand the solution regarding update the network database.

What do mean with "update the host reference in the network database to use the hostname of the new controller" is a specific table inside the "nova" database ??? if yes, what table would that be ?

Is a way also, to know what fields in the database affects

Thanks vish !
