Hi, Byeong-Gi KIM.

In a 3-node deployment, you have a Controller, a Network and a Compute
node. If you want to do a 3-node deployment using only 2 physical
machines, I would deploy the Controller and the Network nodes in one
of the physical machines and deploy the Compute node in the other
physical machine on its own.

However, I don't have any strong reason to backup my suggestion.
That's simply what common sense dictates to me.

Hope it helps.

Cheers,
