Comment 10 for bug 1661693

puppet also uses the product name to provide it's is_virtual fact:

https://github.com/puppetlabs/facter/blob/b0726f54a5e8276ce756a126eb1fdd5b4fb08609/lib/src/facts/resolvers/virtualization_resolver.cc#L74-L94

It knows about "KVM" and a few others, though it at least looks for KVM anywhere in the product name. But it currently won't understand about the above names.

This situation seems like a bit of a mess - no standard way of providing this info, everyone doing their own thing.
