AMI迁移回国。

如果是自己拥有的AMI，需要将AMI存在S3中，再将AMI复制到国内的S3桶从而实现迁移，详见：https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ami-store-restore.html https://aws.amazon.com/about-aws/whats-new/2021/04/amazon-ec2-allows-copy-amazon-machine-images-across-aws-govcloud-aws-china-other-regions/ 如果是marketplace的AMI，则需要用dd命令迁移，详见https://stackoverflow.com/questions/36461042/how-to-copy-an-ami-from-ireland-region-to-china-region-in-aws
