1. API Description

Domain name for API request: cvm.tencentcloudapi.com.

This API is used to restart instances.

  • You can only perform this operation on instances whose status is RUNNING.
  • If the API is called successfully, the instance status will become REBOOTING. After the instance is restarted, its status will become RUNNING again.
  • Forced restart is supported. A forced restart is similar to switching off the power of a physical computer and starting it again. It may cause data loss or file system corruption. Be sure to only force start a CVM when it cannot be restarted normally.
  • Batch operations are supported. The maximum number of instances in each request is 100.

A maximum of 10 requests can be initiated per second for this API.
