Ubuntu 18.04.4 LTS and Thunderbolt 3

Hello,
I am starting with the MangOH Yellow.
I am using Ubuntu 18.04.4 VM on my MacBook Pro with Touch Bar. I only have 4 Thunderbolt 3 and the VM is not communicating with the Mangoh Yellow board.

Appreciate your help.

Seems you need to manually set IP address
