You could upgrade your CPU firmware and get up-to-date packages, but what
about the new CPU types for the guests?
There are no plans to backport the patch for them[1] to 4.0 (though I
assume you could patch your own engine with it!).

I've been only minimally following this discussion as I've had other
things on my plate, but I'm in a similar situation here -- I'm running 4.0
(on EL7.3) on a single host and would rather not upgrade my ovirt
infrastructure to 4.1/4.2 just to get the security fixes for these CPU
bugs.
I don't mind upgrading my host (or engine) to el7.4, provided I can
continue to use ovirt 4.0
But I don't understand what "new CPU types" would be here, or even why
they would be required, to fix these security issues. Perhaps I need a
more basic primer about what actually needs to be patched to fix an ovirt
system against these speculative execution bugs.
Obviously the host systems need to be patched, and KVM most likely needs
to be patched. But do I then need to patch each of my guests? Do I need
to reconfigure anything else?
Is there a minimalist "how to" here?
