We have updated the minimum requirements for OSP 10, and the minimum amount of RAM listed refers to physical memory, and it is expected that you would also have swap >= 1/2 RAM size on top of that.

Unfortunately, I have found that even a 6GB Undercloud is insufficient to deploy an HA overcloud, so really you need at least 8GB of RAM for the Undercloud, preferably more.
