In both of them the bare metal is a ubuntu and I'm using KVM for virtualization. I found that using the virtio interfaces in OpenBSD has a great performance benefit. I doubt that your traffic will make you firewall to fail, if you use PF. Your friends are probably against it because they don't know it.
