[ovirt-users] virt-in-virt problem: DHCP failing for a container in a oVirt VM

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 at 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!

I then went and powered off the VM I'd like to deactivate mac spoof filtering on, then went in to the User Portal and clicked "Edit" on the VM. However, I can not find a "Custom Properties" dialog anywhere in the VM Edit UI (yes, I did enable Advanced options.) Where should I be seeing this?

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