  System details:
  Linux ubuntu 3.16.0-9-generic #14-Ubuntu SMP Fri Aug 15 15:03:57 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux
  Ubuntu Server 14.10 Daily build from 19th Aug.
  
  During the testing we've discovered that the hyperv_fb module is not automatically loaded by the system. 
  The module is used for the 2D FB functionality and in 14.04 and older it was loaded along with all the other Hyper-V LIS kernel modules.
  Please make the necessary corrections to include hyperv_fb as well.
  This affects all Windows Server editions, from 2008R2, WS 2012 and WS 2012 R2.
  
  The module is also used in runlevel 3, and our test setup has the X
  server and GUI installed.
