Do we really want to make this change unconditionally, rather than
only for PVH guests? I'm not sure which (older) OSes look at table
revisions (and may hence end up being incompatible), or whether
OSes may expect certain table versions together with certain base
ACPI versions. I think I had pointed out before that we really
should have the guest config file "acpi=" setting mean a version
number, and table revisions should then be selected according to
that base version. As that's a larger change, simply using one
fixed version for HVM and another for PVH would look fine to me.
