I decided to migrate my virtualization host to FreeBSD bhyve. During installation in my current hardware and one of the issues I had was the ethernet interface not being recognized in the system. Luckily I had access through a usb ethernet so I could run the following steps to make my onboard network work.

  1. Install the package realtek-re-kmod:
pkg install realtek-re-kmod
  1. Add the following 2 lines to your /boot/loader.conf:
if_re_load="YES"
if_re_name="/boot/modules/if_re.ko"
  1. Reboot your server
  2. You should be able to see the your device listed with ifconfig
re0: flags=1008943<UP,BROADCAST,RUNNING,PROMISC,SIMPLEX,MULTICAST,LOWER_UP> metric 0 mtu 1500
  1. Cheers!
