virtualbox.org

I just upgraded my MacBook Pro and used migration assistant. On the new host the Windows VM gets no network. I've checked network settings, refreshed the MAC address but it still gets no network. Since then I've reinstalled VirtualBox and re-copied the known-working VDI file back from the other Mac. I'm at a loss now as to what to try next other than re-install Windows. I have a second VM setup for macOS Sierra that was copied over and networking has no issues there.

We're going to need to see a VM log from a complete VM run:

• Start the VM from cold-boot (not from a paused or saved state) / Observe error / Shutdown the VM (force close it if you have to).
• With the VM completely shut down (not paused or saved), right-click on the VM in the VirtualBox Manager and select "Show Log".
• Save only the first "VBox.log", ZIP it and attach it to your response. See the "Upload attachment" tab below the reply form.

log attached. thank you!

This tells me that you're using Bridged mode over "en0". Typically that's the WiFi adapter on a MBP. Have you tried NAT with this VM? Can you?

You mentioned a second VM. Is the 2nd VM connected with Bridged as well? Over WiFi?

When I switched to NAT it did indeed work. I am using Wifi, and was on my previous Mac. The other VM was set to NAT. Thank you!
