【以下的问题经过翻译处理】 为什么对于标准的Amazon Linux 2 AMI ami-03af6a70ccd8cb578（“amzn2-ami-kernel-5.10-hvm-2.0.20211201.0-x86\_64-gp2”），`aws ec2 describe-images --image-ids ami-03af6a70ccd8cb578` 正常工作并显示：
```
{
    "Images": [
        {
            "Architecture": "x86_64",
            "CreationDate": "2021-12-01T20:06:29.000Z",

            "UsageOperation": "RunInstances",
            "State": "available",
            "BlockDeviceMappings": [
                {
                    "DeviceName": "/dev/xvda",

                        "DeleteOnTermination": true,
                        "SnapshotId": "snap-0d3c07fe7b24df1b8",
                        "VolumeSize": 8,
                        "VolumeType": "gp2",
                        "Encrypted": false
                    }
                }
            ],
            "Description": "Amazon Linux 2 Kernel 5.10 AMI 2.0.20211201.0 x86_64 HVM gp2",
            "EnaSupport": true,

            "ImageOwnerAlias": "amazon",
            "Name": "amzn2-ami-kernel-5.10-hvm-2.0.20211201.0-x86_64-gp2",

            "VirtualizationType": "hvm"
        }
    ]
}
```
但执行这个操作：
`aws ec2 export-image --image-id 'ami-03af6a70ccd8cb578' --disk-image-format VMDK --s3-export-location S3Bucket=XXX,S3Prefix=exports/`
抛出：
``` 
An error occurred (InvalidParameter) when calling the ExportImage operation: The image ID (ami-03af6a70ccd8cb578) provided does not exist. Please make sure the ID is correct.
```

【以下的回答经过翻译处理】 导出镜像存在几个限制，可能会导致错误。这些限制在此文档中有记录：

本情况适用的限制是“如果您从另一个AWS帐户中共享了Amazon EC2的镜像，则无法导出镜像”。如果您使用标准的Amazon Linux 2 AMI，并且该AMI存在于由AWS管理的另一个帐户中，则应该能够将[AMI复制](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/CopyingAMIs.html)到您自己的帐户中，然后使用该AMI ID导出它，只要不涉及其他限制。

执行"export-image" 返回 "InvalidParameter" 提供的镜像 ID 不存在。
