Huge Pages
----------
-VPP requires *'hugepages'* to run. VPP will overwrite existing hugepage settings
-when VPP is installed. By default, VPP sets the number of hugepages on a system
-to 1024 2M hugepages (1G hugepages are no longer supported). This is the number
-of hugepages on the system, not just used by VPP.

If VPP is being run in a Virtual Machine (VM), the VM must have hugepage
- backing. When VPP is installed, it will attempt to overwrite existing
- hugepage setting. If the VM does not have hugepage backing, this will fail,
- but this may go unnoticed. When the VM is rebooted, on system startup,
