We have not seen this issue in https://launchpad.net/ubuntu/+source/util-linux/2.27.1-6ubuntu3.5 version.
So we could like to know if you could include this version in 16.04.04 Ubuntu version..

The expected value is

Hypervisor vendor:   KVM
Virtualization type: para

root at guest:~/util-linux# ./lscpu
Architecture:        ppc64le
Byte Order:          Little Endian
CPU(s):              2
On-line CPU(s) list: 0,1
Thread(s) per core:  2
Core(s) per socket:  1
Socket(s):           1
NUMA node(s):        1
Model:               2.2 (pvr 004e 1202)
Model name:          POWER8 (architected), altivec supported
Hypervisor vendor:   KVM
Virtualization type: para
L1d cache:           32K
L1i cache:           32K
NUMA node0 CPU(s):   0,1

We downloaded the below upstream code and did not see the issue.

  We test what is coming along with distro. If you are not able to see issue with : https://launchpad.net/ubuntu/+source/util-linux/2.27.1-6ubuntu3.5 .. can we get this included in 16.04.x train ?
