Cool. It looks like that works. Perhaps it would be good for oVirt to have a few text fields in the nic properties to enter IP addresses into which can match the rules being used. For example, when enabling the clean-traffic filter it appears the VM can only have 1 IP address, even if another IP is added legitimately, it still only works with the original IP address.
Something like this: http://i.imgur.com/9BUZRCN.jpg So essentially, traffic would be blocked on that VM for any other IP space other than the IP’s entered into the text fields, which then edit/work with the netfilter rules. The idea would be to click “click to add more” would add another text field.

For example, if we provision a VM with one IP, if the user has root access they can simply add random IP’s from within the same range as sub interfaces: eth0:0 eth0:1 eth0:2 so on and so forth. Subnetting is not ideal in this situation because it’s a huge waste of IP space. In oVirt 4.0, you can choose a vnic libvirt filter from a list (at the vnic profile settings). You can check the clean-traffic filter which uses multiple other more specific filters.
