Is this physical hardware? Or a (cloned) VM?

This is hardware

Have you checked that you can connect with the other monitors on port 6789 / 3300 (and vice versa)?

Yes, of course:

root@mon2:/var/lib/ceph

# telnet 10.40.0.81 3300

Trying 10.40.0.81...

Connected to 10.40.0.81.

Escape character is '^]'.

ceph v2

Terminated

root@mon2:/var/lib/ceph

# telnet 10.40.0.83 3300

Trying 10.40.0.83...

Connected to 10.40.0.83.

Escape character is '^]'.
