Can the simple server without GPU run as a host to save and share project data or the host should create a virtual environment and work for all of the machines connected?

Hello,
I would like to ask about “Multi-User Editing”. Me and my friend located in different part of the world and we want to use this feature of the UE4. However we have one question about it. Can the simple server without GPU run as a host to save and share project data or the host should create a virtual environment and work for all of the machines connected?
Thanks,
