Thanks Rafael for adding the bugs already that are related to this.
There also is (for an AMD POV):
"backport extended amd spectre mitigations":
https://bugs.launchpad.net/ubuntu/+source/libvirt/+bug/1840745
But this here is a very special case as it is explicitly asked for UCA Ocata.
The bugs above will cover active Ubuntu releases which atm are Xenial (whitch
matches UCA mitaka), Bionic (matching UCA queens) and newer.
Ocata was based on Zesty which from the base distributions POV is no more
active.
Therefore the Openstack Team needs to decide if they want to pick
changes we have made for Ocata or encourage to move to Queens instead
(if that is an option).
Already for Xenial we have decided to not backport all of these changes, as
strictly speaking they are all just "optimizations" to get out of the drawbacks
of spectre, meltdown and siblings.
The Openstack Team might decide similar for Ocata, but it is up to them so I'll
add a task and assign it to them.
