IceHouse - no valid host was found - RamFilter

Hi,

I'm using Openstack IceHouse on top of one physical machine (all in one) for quiet a while now, and today for some reason I couldn't deploy anymore instances. I'm getting an error on nova scheduler of ram filter returned 0 hosts, which according to my hyper-visor there is still plenty more.
