Ah yes, somehow I missed that. At least that code is standalone too.

Bug #8210: virtual => physical for kvm guests
https://projects.puppetlabs.com/issues/8210#change-65458

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
