Hey @rechjq !
In our test rootfs, we set the IP address depending on the MAC address. Ref: https://github.com/firecracker-microvm/firecracker/blob/main/resources/overlay/usr/local/bin/fcnet-setup.sh
What was your expectation? What issue is this causing you?

Assuming you're following the getting started guide and you were expecting 172.16.0.2, then the MAC should be 06:00:AC:10:00:02.
