[Bug 1659769] Re: virsh nodecpumap --pretty shows unwanted cpu map output

[ChristianEhrhardt]

** Description changed:

+ [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
+ 
+ 
+ ----- original report ------

  Please cherry pick this issue.
