Create emtpy stub files for what will eventually be a new module named
Virtualization Acceleration Code: Unupgradable Units Module (backronym:
VACUUM, or VAC for short). VAC will function as a base module for
multiple KVM modules and will contain the code needed to manage
system-wide virtualization resources, like enabling/disabling
virtualization hardware.
