1. Setup a Fedora 21 VM using virt-builder and import into virt-manager.
2. Download and compile https://www.kernel.org/pub/linux/kernel/v3.x/linux-3.19.tar.xz with CONFIG_IPVLAN=m.
3. Copy the kernel to /boot and add it to grub using grub2-mkconfig and dracut. Reboot.
4. Steps from https://github.com/torvalds/linux/blob/master/Documentation/networking/ipvlan.txt with additional comments --

(a) Create two network namespaces - ns0, ns1
ip netns add ns0
ip netns add ns1
(b) Create two ipvlan slaves on eth0 (master device)
ip link add link eth0 ipvl0 type ipvlan mode l2
