That's still unclear, even after having read this message.

You should state what is your actual _end_goal_. Only in that case we
can figure out if you're posting in the right list and, if yes, how to
help you.

I don't understand what you mean with "two identical vcpus". What is it
that makes two vcpus identical (or different)?

Not if you're not more clear on what you want to achieve.

The scheduler, for example, can help if you want that two or more vcpus
_always_ executes at the same time, on different pcpus (in the sense
that you can modify it so that it will believe that way, it's not
something that is supported out of the box right now).

Is this what you meant with "having two or more from one vcpu when
creating and then run them together on different cores"?
