Description

Constraints

TrustedSystemMode

String

The trusted system mode.

Valid value: vTPM. Currently, the trusted system mode is supported by the following instance families: g7, c7, and r7. It is also supported by security-enhanced instance families: g7t, c7t, and r7t. When you create an ECS instance of these instance families, you must set this parameter. Details are as follows:

If you use the Alibaba Cloud Trusted System, set this parameter to vTPM. When the instance starts, the Alibaba Cloud Trusted System completes the trusted verification. If you do not use the Alibaba Cloud Trusted System, you can leave this parameter empty. However, if the ECS instance you create uses the enclave confidential computing mode (SecurityOptions.ConfidentialComputingMode=Enclave), the trusted system is also enabled for the ECS instance. To create an ECS instance with a trusted system using an OpenAPI, you can only call RunInstances. CreateInstance does not currently support setting the SecurityOptions.TrustedSystemMode parameter.

Note

If you specify the instance as a trusted instance when you create it, you can only use images that support the trusted system when you replace the system disk.
