  UPDATE 4/10/2016: NX-OSv (Titanium) – end of development
  The NX-OSv virtual machine image that has been provided with VIRL is based on the Titanium development platform, using the NXOS operating system with a hardware model based on the NEXUS 7000-series platform.
  The virtual machine provides Layer-3 and management-plane features taken from the 7.x.x version of the NXOS operating system. As many of you will be aware, Layer-2 switching functionality is not present in the image.
  Development efforts in the NXOS operating system, are now strongly focused on moving to the next generation NXOS as implemented today on the NEXUS 9000-series platform. To that end, Layer-2 and Layer-3 feature development is aligned toward the next generation NXOS virtual machine platform. As a result, there are no plans to deliver Layer-2 switching features on the NX-OSv (Titanium) virtual machine platform.
  The first virtual machine platform using the next generation NXOS operating system will be NXOSv9000, which is expected to be available on VIRL in late 2016.
