First mitigation was to edit "agent.conf" and add the host.cpu.manual.speed.mhz - option manually. So the hosts are availeable for migration purposes.
So actually the warning " [kvm.resource.LibvirtComputingResource] (agentRequest-Handler-3:null) (logid:44ab098e) Couldn't retrieve free memory, returning -1. " is left to deal with. Any help / information is appreciated. Regards Chris Am So., 28.
