I think we should just do nothing. If people/apps care about optimal defaults, nothing libvirt changes will make them happy. Apps need to be just using libosinfo to get the sensible defaults on a per OS basis.
This is not about optimal defaults though, it's about being able to install the OS at all without having to explicitly specify that you want to use virtio: $ sudo virt-install \ [...] \ --os-variant=rhel7.0 \ --network network=default ERROR internal error: early end of file from monitor: possible problem: 2015-09-03T09:00:42.154356Z qemu-kvm: -device rtl8139,netdev=hostnet0,id=net0,mac=52:54:00:d4:d8:8f,\ bus=pci.0,addr=0x1: 'rtl8139' is not a valid device model name This happens because we assume rtl8139 will be available, but that's not the case eg. on RHEL ppc64.
