I am using ovirt 4.3. I am in need to isolate all my VM from each other (without using VLAN) except to a virtual gateway which is also the DHCP server.

Basically only allowing traffic from 1 MAC address to another MAC address. Everything else should be filter out by ovirt filtering subsystem

How will I go about that? I can see in network profile the ability to set different filter but can't find a way to create new filter.

Does the Doc Text of

Bug 1009608 - [RFE] Limit east-west traffic of VMs with network filter

https://bugzilla.redhat.com/show_bug.cgi?id=1009608

explain the configuration of the filter?

Please note that there will be isolated ports

https://www.ovirt.org/develop/release-management/features/network/isolated-ports.html

available in ovirt-4.4.3 on CentOS 8.3 , which might address your scenario even better.

Thanks for your help
