Hi, Ruben.

Thanks for your explanation. I understand the problem now.

We could add a VCPU option to specify the number of virtual CPU's, and
use the CPU setting (rounded up) as the default value for the VCPU
setting? That way, we maintain the current semantics for the CPU
setting, and add a way to customise the number of virtual cpu's assigned
to a virtual machine.
