Bug Description

+++ This bug was initially created as a clone of Bug #171443 +++
Please, add the following patch:
http://
which adds a mode where all vCPUs on a core must be the same VM on POWER8 and POWER9.
This is intended for use in security-conscious settings where users are concerned about possible side-channel attacks between threads which could perhaps enable one VM to attack another VM on the same core, or the host.

Hello Canonical,
This has been included in Ubuntu 18.04 and Ubuntu 18.10 on Launchpad 1792957. Is there anything blocking its inclusion in Ubuntu 16.04 as well?
