Feature #24598
Randomize default VM NIC Mac Address to avoid conflicts
Description
It appears the default NIC device for created VM has MAC address of 00:a0:98:43:a0:50, which causes routing conflicts if you have more than 1 FreeNAS device hosting VMs on your network if you do not realize this. The MAC address should be randomized on creation of any VM.

Hello Marcelo,
Is it expected that the vm Mac Address is different on every boot? Should this be generated randomly on the creation of the network device and saved in the config so it is persistent. It's currently breaking vm's getting the same ip addresses from dhcp will also break static dhcp assignments
Thanks,
Nick

Yes, if the MAC ADDRESS are not set on the UI, that should be the correct behavior. It was made in that way, because I got reports from users with 2 or more FreeNAS in the same network having mac collision.
For the DHCP case, you can set a static MAC on each NIC of a vm guest.
Best,
Thanks,
Nick
