Sadly, having set the 'macspoof' key to 'true' in Custom Properties in the VM 
Edit dialog, then restarting the VM thereafter, I'm still not seeing the 
container's MAC address in the relevant bridge's MAC table in oVirt, and the 
container is failing to lease a DHCP address from the external network... 

Looked at the ebtables filter table, nothing there...
[root@ovirt-node-03 ~]# ebtables -t filter -L
Bridge table: filter

Bridge chain: INPUT, entries: 0, policy: ACCEPT

Bridge chain: FORWARD, entries: 0, policy: ACCEPT

Bridge chain: OUTPUT, entries: 0, policy: ACCEPT

Anyone know where else I could look to troubleshoot?

Yup, I see it now in the Admin portal VM Edit dialog - thanks!

Iirc it's not in user portal by design. All custom properties are generally 
considered admin-like stuff
