I am running an Ubuntu 16.04.2 guest on a Mac host.

I am migrating a VMware Fusion VM from another Mac:

1. Creating a new VM using an existing disk.
2. Pointed disk at VMWare Fusion's .vmdk.
3. Memory set to 2048M.
4. Defaults for everything else.

The VM boots fine but when I run ifconfig on the guest it only finds the loopback interface, lo.

I tried to reset the network:

1. Shutdown the VM.
2. Disabled network. It was originally "NAT".
3. Rebooted guest.
4. Shutdown guest.
5. Reenable network: "NAT".
6. Rebooted.
7. ifconfig on guest: lo only

The network on VMware Fusion was originally "Local to my Mac". Why is the network device not recognized?

Make sure that all VMWare guest additions have been eliminated from the guest.

Or, create a VirtualBox VM from scratch.

I don't believe that Guest Additions was ever installed on VMware. Is there a way to verify?

I expect so. But you'd need to ask a VMWare expert about that.

If this VM was used in VMWare for any length of time then IMHO it's highly unlikely that the tools were never installed.
