Issue #8210 has been updated by Andreas Ntaflos.
As reported some time ago in #16559 when copying the physical host's CPU
configuration into the KVM guest, `facter is_virtual` reports `false` and
`facter virtual` reports `phyical`, even though it indeed is a virtual machine.
This happens with Facter 1.6.17 and Puppet 3.1.0 on Ubuntu 12.04 (x86_64) both
as host and guest, using KVM (currently 1.0+noroms-0ubuntu14.7) and Libvirt
(0.9.8-2ubuntu17.7). In `/proc/cpuinfo` this looks as follows on the virtual
machine/guest:
processor : 0
vendor_id : GenuineIntel
cpu family : 6
model : 15
model name : Intel(R) Core(TM)2 Duo CPU T7700 @ 2.40GHz
stepping : 11
microcode : 0x1
cpu MHz : 3058.998
cache size : 4096 KB
fpu : yes
fpu_exception : yes
cpuid level : 10
wp : yes
flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca
cmov pat pse36 clflush mmx fxsr sse sse2 ss syscall nx pdpe1gb rdtscp lm
constant_tsc rep_good nopl pni vmx ssse3 cx16 sse4_1 sse4_2 popcnt aes
hypervisor lahf_lm
bogomips : 6117.99
clflush size : 64
cache_alignment : 64
address sizes : 40 bits physical, 48 bits virtual
So it seems this the fix that made it into Facter 1.6.14 does not work
universally. Can I provide anything to help debug and fix this further?

Bug #8210: virtual fact should work for EL kvm guests
https://projects.puppetlabs.com/issues/8210#change-86927
Author: Markus Falb
Status: Closed
Priority: Normal
Assignee:
Category: library
Target version: 1.6.14
Keywords:
Branch: https://github.com/puppetlabs/facter/pull/340
Affected Facter version: 1.6.2
The Output from /proc/cpuinfo can not used reliable for telling that it is a
kvm virtual machine.
On a CentOS 5.6 kvm Host with CentOS guests /proc/cpuinfo tells me:
for a smp guest
model name : QEMU Virtual CPU version 0.9.1
with only one cpu in the guest:
model name : Pentium II (Klamath)
but in both cases:
$ dmidecode -t 4
...
Manufacturer: QEMU
...
I believe it is possible to specify what cpu is used so on the commandline, so
relying on the model name is not always working
