Hi Yes I agree with Steffen, I'd be surprise this is something related to DB access. A couple of thoughts from your data:
1.- Prolog Times constant means that your are not suffering an storage problem 2.- Pending Times increasing. This depends on the number of VMs to schedule, and the number of available resources. The default scheduler parameters are quite conservative in order not to overload the other systems but this can be tunned considering each setup. There are huge improvements in performance in OpenNebula 2.2 and OpenNebula 3.0 in this area. 3.- Increase Boot times depends directly on the hypervisor. This usually increases when starting multiple VMs in the same host at the same time.
