[Observium] Hardware showing as generic not openvz

Hi All

Im trying to work out if im being stupid or something isnt right?

Some machines we monitor are showing the hardware as 'OpenVZ Containers' but others are being found as 'Generic x86'

I have installed the distro script on all the machines and im using the latest version 2.0 script

Output from one of the machines which is an openvz container - Linux|4.4.0|amd64|Ubuntu|16.04||openvz

Am I missing something?

Regards

Simon
