You can only turn on AMD SEV-SNP when you launch an instance. When AMD SEV-SNP is turned on for your instance launch, the following rules apply.

  • AMD SEV-SNP can't be turned off. It remains on throughout the instance lifecycle.

  • You can only change the instance type to another instance type that supports AMD SEV-SNP.

  • Hibernation and Nitro Enclaves aren't supported.

  • Dedicated Hosts aren't supported.

  • If the underlying host for your instance is scheduled for maintenance, you'll receive a scheduled event notification 14 days before the event. You must manually stop or restart your instance to move it to a new host.
