SEV is targeted to the VM instances, with a single key per VM. SME is applicable to the entire server, similar to total memory encryption with a single key for all host kernel/machine. SME is not super applicable to the cloud, more suitable for a single server environments.

That doesn't tell me what mode of AES it is, that's key management.

Respectfully, I know that. That doesn't say if its ECB, CTR, XTS, etc. What mode AMD uses makes has huge implications on what it is good for and not good for.
