This is not a bug with the kernel, different processors expose if they
are 'hardware virtualization' capable in different ways.

If using systemd, you can just use 'systemd-detect-virt'.

If you want to see how that patch was done in systemd, you can look here:
https://github.com/arges/systemd/commit/121bcf6d8a2d84cac732d66677440e432fcbf8fd

Essentially check here:
cat /sys/firmware/devicetree/base/hypervisor/compatible

Title:
  IBM Power8 PowerNV does not expose kvm capabilities

Status in linux package in Ubuntu:
  Invalid

Bug description:
  Power8  in PowerNV mode with Ubuntu installed does not expose kvm cpu
  capabilities:

  ubuntu@powereight:~$ lsmod |grep kvm
  ubuntu@powereight:~$ 

  ubuntu@powereight:~$ egrep -o "vmx|svm" /proc/cpuinfo
  ubuntu@powereight:~$ 

  
  In this same mode with PowerKVM installed, the machine does have kvm capabilities.
