No valid host found means that the scheduler doesn't find a host suitable to run your instance. For example, the hosts in the AZ may not have sufficient memory/disk/CPU resources, or the wrong architecture.
The scheduler log may have details. For full detail, switch on debug logging.

I am surprised you have a scheduler on the compute node, but perhaps that's particular for OVM. The error indicates incorrect database permissions setup, or perhaps an incorrect database connection string in nova.conf.
The scheduler log on the controller contains no info about scheduling.
