Doc Text:
.Virtual machines now work correctly on RHEL 7 nodes in RHOSP 10 Previously, upgrading a Red Hat Enterprise Linux 7 (RHEL 7) node in Red Hat OpenStack Plaform 10 (RHOSP 10) to a later minor version sometimes caused virtual machines (VMs) hosted on that node to become unable to start. This update fixes how the `tuned` service configures parameters of the _kvm-intel_ module, which prevents the described problem from occurring.

I am OK with the z-stream fix.

Upstream commit addressing the problem:

It may look a bit over-engineered, but it's done this way to lower the possibility of race condition during Tuned startup / modules loading.
