Issue #8210 has been updated by Andreas Zuber.
On RedHat/CentOS KVM hosts the guest sees the processor manufacture "Bochs". I
tested this with Centos, Ubuntu and FreeBSD, the model name seams to depend on
the architecture while the manufacturer remains "Bochs". What i could not test
was if that works on Non-RedHat KVM hosts.

Bug #8210: virtual => physical for kvm guests
https://projects.puppetlabs.com/issues/8210#change-55345
Author: Markus Falb
Status: Re-opened
Priority: Normal
Assignee: shubhra sinha varma
Category: library
Target version: 1.6.x
Keywords:
Branch:
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
