Description

TrustedSystemMode

String

The trusted system mode.

Valid value: vTPM. Currently, the trusted system mode is supported by the g7, c7, and r7 instance families, and the security-enhanced instance families (g7t, c7t, and r7t). You must set this parameter when you create ECS instances of these instance families. The details are as follows:

If you use the Alibaba Cloud Trusted System, set this parameter to vTPM. This allows the instance to complete a trusted verification through the Alibaba Cloud Trusted System upon startup. If you do not use the Alibaba Cloud Trusted System, you can leave this parameter empty. However, note that 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. When you use OpenAPI to create an ECS instance with a trusted system, you can only call RunInstances. CreateInstance does not currently support setting the SecurityOptions.TrustedSystemMode parameter.

Note

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