Javier We saw that VM's were being deployed to the host where the allocated memory of all the VM's was higher than the available memory on the host.
We think OpenNebula is executing free command on the host to determine if there is any room and since free would always return the actual memory that is being consumed and not the allocated, opennebula would push the new jobs to the host. That's the reason we want OpenNebula to be aware of memory allocated to the VM's on the host.
