You may already know this, but don't rely on hyperthreading giving you very much extra. At best it's squeezing some useful work out of what would be a few idle cycles waiting for the instruction pipeline to re-fill. At worst it degrades performance and has been known to be a security hazard. Therefore, in your given case, think six not twelve. Common advice is to leave one core for the host OS/scheduler. Which leaves you with 5 physical CPUs to allocate.
