I have two virtual machines running on Parallels desktop (v11 if that makes a difference). They are operating in Shared network mode.

When I have a wireless or Bluetooth network connection they can communicate between each other fine.

When I lose that connection (phone tether drops out, flying, etc) the virtual machines no longer are able to communicate with each other.

I have also tried the network in Host Only mode to no avail.

Is there some way I can have these virtual machines communicate with each other even when I do not have an external network connection?

  • Do you mean it cannot communicate outside its virtual subnet or it cannot communicate with each other on the same virtual subnet?

  • Clearly, they're not actually operating over your local network—it's traveling from you, out over the wider internet, then back to you your local machine. Why, I don't know. Oct 6, 2018 at 0:55

From Parallels Knowledge Base the following indicates an internet connection is required for this to work. No idea why that would be a requirement.
