No, these ifup/ifdown udev rules should not be running for veth devices. They are not normal NICs - they are the same usage scenario as Xen vif devices or tap devices in QEMU. The suse 77-network.rules script is already whitelisting the vif* and tap* to avoid this behaviour for those devices and it should be doing the same for veth* devices too.
