RancherOS VM fails to boot with MAC address set

[d1981]

Just updated to FreeNAS-11.1-U4 and now my RancherOS VM won't start if the MAC address is set. I originally used this guide, https://doc.freenas.org/11/vms.html , and it was working fine. If I remove the mac address from the VM nic device, it boots.

What error do you get in /var/log/messages when you try to start with the MAC address set?

This is what I see when trying to start it with a MAC address set

Code:

Mar 24 09:08:29 PILOT dhclient[94124]: Interface tap0 is down, dhclient exiting

Mar 24 09:08:29 PILOT dhclient[93422]: connection closed

Mar 24 09:08:29 PILOT dhclient[93422]: exiting.

Mar 24 09:08:29 PILOT kernel: tap0: link state changed to DOWN

Mar 24 09:08:29 PILOT kernel: tap0: link state changed to DOWN

Mar 24 09:08:30 PILOT tap0: Ethernet address: 00:bd:e0:6f:5b:00

Mar 24 09:08:30 PILOT kernel: tap0: promiscuous mode enabled

And without MAC address and Rancher booting:

Code:

Mar 24 09:08:30 PILOT tap0: Ethernet address: 00:bd:e0:6f:5b:00

Mar 24 09:08:30 PILOT kernel: tap0: promiscuous mode enabled

Mar 24 09:09:33 PILOT tap0: Ethernet address: 00:bd:61:67:5c:00

Mar 24 09:09:33 PILOT kernel: tap0: promiscuous mode enabled

Mar 24 09:12:10 PILOT tap0: Ethernet address: 00:bd:51:cc:5e:00

Mar 24 09:12:10 PILOT kernel: tap0: promiscuous mode enabled

Mar 24 09:12:10 PILOT kernel: tap0: link state changed to UP

Mar 24 09:12:10 PILOT kernel: tap0: link state changed to UP

Hi,

I made some extra tests and the feature works OK.
I set this MAC via UI: 68:f7:28:5f:db:55

My docker machine did boot OK without any issue, and from inside my docker machine:

Code:

[root@rancher rancher]# ifconfig eth0 | grep HWaddr
eth0	  Link encap:Ethernet  HWaddr 68:F7:28:5F:DB:55 

NOTE: If you add a MAC ADDRESS that is in use in your network, you will have a MAC collision. Isn't your case?
