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.
Thank you. I never planned to allocate to any guest more cpus that were physically available. What I was checking was that a single physical cpu with four cores actually counted as four cpus insofar as kvm itself was concerned. I have allocated guests their processors on the basis that 1 core = 1 cpu. But it occurred to me that core might actually mean something different and so I wanted to verify my understanding.

You are welcome. It took me forever to get a straight answer on this issue (~3 years). I am glad I could share it with you.
