Bug #10879: Does not detect KVM VM as a virtual machine when kvm provides an
existing CPU

Affected Facter version: 1.6.2
I am using custom CPU flags to launch a qemu-kvm virtual machine: qemu-kvm is
launched with this parameter:
-cpu
phenom,+wdt,+skinit,+osvw,+3dnowprefetch,+misalignsse,+sse4a,+abm,+cr8legacy,+extapic,+cmp_legacy,+lahf_lm,+rdtscp,+pdpe1gb,+popcnt,+cx16,+ht,+vme
Because of that, /proc/cpuinfo does not mention QEMU as CPU vendor anymore but
mentions a real physical CPU. Now facter thinks that I am using a physical
machine:
# facter | grep virtual
is_virtual => false
virtual => physical
