Currently, the sev-guest driver uses the vmpck-0 key by default. When an SVSM is present, the kernel is running at a VMPL other than 0 and the vmpck-0 key is no longer available. If a specific vmpck key has not be requested by the user via the vmpck_id module parameter, choose the vmpck key based on the active VMPL level.
