Different CPU generations have different limits on the number of SEV/SEV-ES guests that can be run. Since both limits come from the same overall set, there is typically also BIOS config to set the tradeoff betweeen SEV and SEV-ES guest limits. This is important information to expose for a mgmt application scheduling guests to hosts. Reviewed-by: Peter Krempa <pkrempa@redhat.com> Signed-off-by: Daniel P. Berrangé <berrange@redhat.com>
