You can run OpenStack on a single node without switch, but I doubt you want this answer. I think that OpenStack requires nodes to be on the same network, but if they are not connected via switch, perhaps you could connect them to an overlay network. How are your nodes connected if not via switch?

Floating IPs are managed by routers connected to provider networks, so the second answer is no. See also https://assafmuller.com/2018/07/23/te....

my nodes are not connected using a physical switch. I think they are connected with virtual switches.

If i am using a switch, should i change anything in the OpenStack configuration (e.g., mangement interface, provider interface, etc) ?

As long as they are on the same layer 2 network, i.e. can talk to each other with MAC addresses, it should be OK. Everybody uses virtual machines connected with virtual switches to deploy OpenStack for fun and study.
