Title:
  virsh nodecpumap --pretty shows unwanted cpu map output

Status in libvirt package in Ubuntu:
  Fix Released
Status in libvirt source package in Xenial:
  Fix Released

Bug description:
  [Impact]

   * virsh nodecpumap --pretty --pretty shows wrong result on machine with    
     many cores

   * Since admin and scripts might rely on those they should be fixed.
     Not only are they not nice, they are depending on the case even wrong 
     sometimes.

   * an example is like:
     virsh nodecpumap --pretty
     CPUs present:   120
     CPUs online:    120
     CPU map:        0-119,192,196,199,258,262,264,267,269-270,272-273,276-278,284-286,290-291,293-294,296,301-302,304,307-310,314,316,318,320,322,325-326,331-334,338,340-342,802-803,805,807-809,813-814,816-818,821-822,825,828-829,831,833,836

  
  [Test Case]

   * Go to a huge machine with many CPUs (a virtual machine with faked vcpus 
     might help, but stay aware of issues with 2nd level virtualization)

   * run "virsh nodecpumap --pretty"

   * Tests with extra splits into numa nodes can be done, but are not 
     necessary to show the effect

  [Regression Potential]

   * Fix is upstream quite while now without further changes which
  should make it safe.

   * Also since the code is restricted to "virsh nodecpumap" and not reused 
     any potential regression should be limited to that sub-command which is
     nice for some use-cases but not a core function in general.

  [Other Info]
   
   * n/a
