Description Jan Stancek 2016-06-07 07:58:59 UTC 
Description of problem:
Inventory task is not detecting HVM key/value correctly on PowerNV systems. AFAIK all PowerNV systems are capable of KVM, but adding similar test as for x86 that detects that kvm_hv can be loaded shouldn't hurt anything.

# cat /proc/cpuinfo  | grep platform 
platform        : PowerNV

# lsmod | grep kvm
kvm_hv                103171  1 
kvm                   176191  5 kvm_hv

# modinfo kvm_hv

How reproducible:
100%

Steps to Reproduce:
1. run inventory on bare metal ppc system


Actual results:
HVM=0

Expected results:
HVM=1

Kinda wish we had something better than looking in /sys/modules for random module names, but anyway...

Patch to make beaker-system-scan recognise kvm_hv:

Patch to make /distribution/inventory modprobe it:
