   ========================
   Before VMs can make use of the SEV feature you need to make sure your

^this change should go along the (<6.4.0) in one of the earlier patches into a
standalone patch.

Actually the earlier patches fix the stale cap cache and this update is
because of a new support in libvirt-host-validate. I am not sure that we
should tie these to into one patch.
I would prefer to keep the two doc changes separate and with the changes
that caused the update.

I won't argue against that logic. However, both patch 3 and this one update the
same knowledge article. What IMO matters here the most is that once all of the
changes you're introducing are applied as a unit, the article needs to
reflect both the changes. From that perspective, at least to me it makes total
sense to group the docs changes from both 3/6 and this patch to a single update
to the SEV article accordingly.

Fine, I will sort out the changes and create a single AMD doc update patch.
