[Bug 1461012] Re: Hugepage and KSM not configured correctly under systemd

[Serge Hallyn]

** Description changed:

+ ================================================================
+ Impact: hugepages not available for use by kvm
+ 
+ Fix: systemd uses the sysvinit qemu-kvm job rather than the more
+ uptodate upstart job.  To keep those in sync, the fix switches to a
+ single common script which is run by both the upstart and sysvinit (and
+ therefore systemd) scripts.
+ 
+ Test case: ls /run/hugepages
+ 
+ Regression potential: since init scripts are being moved around, there is a potential for this to go wrong.
+ ================================================================
+ 
  As stated by Dadio (dominique-ramaekers) in ticket #1315402:

  So, old LSB script should be removed (or disabled) when new qemy-
  kvm.service will be added for systemd.
