I think page granularity is needed, because some regions shared with the HV are only one page in size (the GHCBs in SEV-ES for example). But in general it is worth to discuss whether validating memory in bigger chunks than a page is beneficial wrt. to allocation latency vs. required HV round-trips for validation. Regards, Joerg
