I don't really agree with this. People using OpenVZ or LXC are simply not
refering to their guests as virtual machines because it makes no sense
as a term in this context.

No, not really. This is a completely different scenario. You haven't got two 
fundamentally different concepts here, this is just a Xen vs KVM vs VMWare
scenario where you've just got different impls of the same concept.
