You may use the [DescribeInstances](https://intl.cloud.tencent.com/document/api/213/15728?from_cn_redirect=1) API to query instances and use the project ID to filter the results. You cannot modify the project of an instance that is bound to a load balancer. You need to unbind the load balancer from the instance by using the [DeregisterInstancesFromLoadBalancer](https://intl.cloud.tencent.com/document/api/214/1258?from_cn_redirect=1) API before using this API. Batch operations are supported. Up to 100 instances per request is allowed. You can use the API [DescribeInstances](https://intl.cloud.tencent.com/document/api/213/15728?from_cn_redirect=1#.E7.A4.BA.E4.BE.8B3-.E6.9F.A5.E8.AF.A2.E5.AE.9E.E4.BE.8B.E7.9A.84.E6.9C.80.E6.96.B0.E6.93.8D.E4.BD.9C.E6.83.85.E5.86.B5) to query the operation result. If the `LatestOperationState` in the response is `SUCCESS`, the operation is successful.

    This API is used to modify the VPC attributes of an instance, such as the VPC IP address. This action will shut down the instance, and restart it after the modification is completed. To migrate an instance to another VPC/subnet, specify the new VPC and subnet directly. Make sure that the instance to migrate is not bound to an [ENI](https://intl.cloud.tencent.com/document/product/576?from_cn_redirect=1) or [CLB](https://intl.cloud.tencent.com/document/product/214?from_cn_redirect=1) instances.

    This API is used to reinstall the operating system of the specified instance. If you specify an `ImageId`, the specified image is used. Otherwise, the image used by the current instance is used. The system disk will be formatted and reset. Therefore, make sure that no important files are stored on the system disk. If the operating system switches between `Linux` and `Windows`, the system disk `ID` of the instance will change, and the snapshots that are associated with the system disk can no longer be used to roll back and restore data. If no password is specified, you will get a random password via internal message. You can only use this API to switch the operating system between `Linux` and `Windows` for instances whose [system disk type](https://intl.cloud.tencent.com/document/api/213/9452?from_cn_redirect=1#SystemDisk) is `CLOUD_BASIC`, `CLOUD_PREMIUM`, or `CLOUD_SSD`. Currently, this API only supports instances in Mainland China regions.

    This API is used to change the public bandwidth cap of an instance. The allowed bandwidth cap varies for different models. For details, see [Purchasing Network Bandwidth](https://intl.cloud.tencent.com/document/product/213/509?from_cn_redirect=1). For bandwidth billed by the `TRAFFIC_POSTPAID_BY_HOUR` method, changing the bandwidth cap through this API takes effect in real time. Users can increase or reduce bandwidth within applicable limits.

    This API is used to reset the password of the operating system instances to a user-specified password. To modify the password of the administrator account: the name of the administrator account varies with the operating system. In Windows, it is `Administrator`; in Ubuntu, it is `ubuntu`; in Linux, it is `root`. To reset the password of a running instance, you need to set the parameter `ForceStop` to `True` for a forced shutdown. If not, only passwords of stopped instances can be reset. Batch operations are supported. You can reset the passwords of up to 100 instances to the same value once. You can call the [DescribeInstances](https://intl.cloud.tencent.com/document/api/213/15728?from_cn_redirect=1#.E7.A4.BA.E4.BE.8B3-.E6.9F.A5.E8.AF.A2.E5.AE.9E.E4.BE.8B.E7.9A.84.E6.9C.80.E6.96.B0.E6.93.8D.E4.BD.9C.E6.83.85.E5.86.B5) API and find the result of the operation in the response parameter `LatestOperationState`.

    This API is used to change the model of an instance. You can only use this API to change the models of instances whose [system disk type](https://intl.cloud.tencent.com/document/api/213/9452?from_cn_redirect=1#block_device) is `CLOUD_BASIC`, `CLOUD_PREMIUM`, or `CLOUD_SSD`. Currently, you cannot use this API to change the models of [CDH](https://intl.cloud.tencent.com/document/product/416?from_cn_redirect=1) instances.
    
    Parameters:
    
    req - ResetInstancesTypeRequest

```
    This API (ResizeInstanceDisks) is used to expand the data disks of an instance. Currently, you can only use the API to expand non-elastic data disks whose [disk type](https://intl.cloud.tencent.com/document/api/213/9452?from_cn_redirect=1#block_device) is `CLOUD_BASIC`, `CLOUD_PREMIUM`, or `CLOUD_SSD`. You can use [`DescribeDisks`](https://intl.cloud.tencent.com/document/api/362/16315?from_cn_redirect=1) to check whether a disk is elastic. If the `Portable` field in the response is `false`, it means that the disk is non-elastic. Currently, this API does not support [CDH](https://intl.cloud.tencent.com/document/product/416?from_cn_redirect=1) instances. Currently, only one data disk can be expanded at a time.
    
    Parameters:

                                  throws TencentCloudSDKException
```
    This API is used to create one or more instances with a specified configuration. After an instance is created successfully, it will start up automatically, and the [instance status](https://intl.cloud.tencent.com/document/api/213/9452?from_cn_redirect=1#instance_state) will become "Running". If you create a pay-as-you-go instance billed on an hourly basis, an amount equivalent to the hourly rate will be frozen. Make sure your account balance is sufficient before calling this API. The number of instances you can purchase through this API is subject to the [Quota for CVM Instances](https://intl.cloud.tencent.com/document/product/213/2664?from_cn_redirect=1). Instances created through this API and in the CVM console are counted toward the quota. This API is an async API. An instance ID list is returned after the creation request is sent. However, it does not mean the creation has been completed. The status of the instance will be `Creating` during the creation. You can use [DescribeInstances](https://intl.cloud.tencent.com/document/api/213/15728?from_cn_redirect=1) to query the status of the instance. If the status changes from `Creating` to `Running`, it means that the instance has been created successfully.
    
    Parameters:
    
    req - RunInstancesRequest
    
    Returns:
    
    RunInstancesResponse
