Ubuntu VM and NIC

[tsr966]

I want to create an Ubuntu VM and utilize a separate NIC i have on my R720XD. I tried this initially and chose a NIC that wasn't the primary NIC for freenas. It worked fine until i rebooted and then it locked up my network. The switch went crazy and all the light flashed rapidly in sync. I couldn't log into freenas to fix it so i unplugged the network from that NIC and was able to boot up and delete the VM. I want to try it again but i want to know what i did incorrectly so i don't cause that loop again

Were you able to resolve this? If not, which FreeNAS version? What is the full output of ifconfig (within code tags)?
