[Bug 1170325] Re: Facter 1.6.X not considering Qemu/KVM virtual type

[Robie Basak]

** Description changed:

  [Impact]
  
  facter recognises a /proc/cpuinfo CPU model of "Common KVM processor" as
  a physical machine. facter is most often used with puppet, and causes
  puppet manifests to mis-classify virtual machines of this type and apply
  incorrect rules where the puppet manifests supplied by system
  administrators differ on this criterion.
  
  [Stable and Development Fix]
  
  A cherry-pick of the upstream fix, modified to be made minimal (one
  line). See the quilt patch for details.
  
  [Test Case 1]
  
  Run "facter is_virtual". On a physical machine, this should say false.
  On a virtual machine reporting in /proc/cpuinfo as "QEMU Virtual CPU" as
  well as a virtual machine reporting in /proc/cpuinfo as "Common KVM
  Processor", "facter is_virtual" should say true.
  
  [Test Case 2]
  
  As a shortcut, on Quantal and Raring you can fake the /proc/cpuinfo file
  as follows:
  
  mkdir -p /tmp/proc/{lower,upper,combined}
  cd /tmp/proc
  mount -t proc none lower
  mount -t tmpfs -o mode=755 none upper
  mount -t overlayfs -o lowerdir=lower,upperdir=upper none combined
- stop rsyslogd
+ stop rsyslog
  stop acpid
  umount /proc && mount --bind combined /proc
  
  Then you can edit /proc/cpuinfo and run facter to test behaviour as per
  Test Case 1.
  
  This is a hack and does not appear to work correctly in Precise.
  
  [Regression Potential]
  
  It looks like detection of other model strings in /proc/cpuinfo may have
  regressed upstream, fixed by a later commit. It's important to test that
  both model strings of "QEMU Virtual CPU" and "Common KVM processor"
  detect as virtual, and that another string (eg. "Other") detects as
  physical.
  
  [Original Description]
  
  On ubuntu 12.04 LTS, the official version for the facter package is
  1.6.5-ubuntu1.
  
  ii facter 1.6.5-1ubuntu1 collect and display facts about the system
  
  The is_virtual? method is not recognized on last version of KVM, because
  of the output of /proc/cpuinfo, which does not contains “Qemu Server”
  Infos.
  
  model name : Common KVM processor
  
  The workaround was added in the next versions of facter, and so I would
  like to provide you this patch, which fixes this bug on Ubuntu 12.04
  LTS.
  
  Best regards
