Title:
  Xen guest total memory size smaller than specified in virtual
  configuration due to Xen balloon driver

Status in linux package in Ubuntu:
  Fix Released

Bug description:
  [Impact]

  On virtual systems under Xen, the kernel does not correctly calculate
  the total amount of memory.  This results in the system having
  slightly less memory available for use than the actual amount provided
  by Xen.

  [Fix]

  See first comment.

  [Test Case]

  Load a virtual Xen guest with the latest precise (3.2) kernel, and
  notice that its total memory is less than what is allocated in the Xen
  configuration.  Also possible is to load a virtual Xen guest, with the
  exact same Xen guest config/parameters, with the latest trusty (3.13)
  kernel; on trusty and later, the total amount of memory is correctly
  detected.

  [Regression Potential]

  None known.
