Thanks for you responses and sorry for not specifying the guest's device tree.
I've summed up your proposals and sketched and algorithm: N - the number of vcpus from the '-c' parameter X - the number of vcpus from the device tree if there isn't the parameter -> start the vm with X vcpus if there is the parameter --> if N <= X -> start the vm with N parameters |-> if N > X -> throw an error I believe this gives the opportunity to rebuild the device tree and use all vcpus (first branch) or let the device tree as it is (more vcpus) but use only a subset of them. Is this alright?
