| fault | {u'message': u'No valid host was found. ', u'code': 500, u'created': u'2013-12-18T08:44:07Z'}

I found the error "Error: Unable to associate floating IP. "

but I don't know how to resolve it.

This means most propably that there is no compute host that can boot that image. Maybe the flavor has more RAM then what is maximum on the compute host?

Can you give us more details about your configuration: host cpu/ram and what overcommiting you have, how many VMs are already runnning?
