Question

aws ec2 run-instances --region us-west-2 --image-id ami-d732f0b7 --count 1 --instance-type t1.micro --security-groups launch-wizard-1 --key-name key-name

返回的错误是：

An error occurred (InvalidParameterCombination) when calling the RunInstances operation: Non-Windows instances with a virtualization type of 'hvm' are currently not supported for this instance type.

但是，从Web控制台我可以使用相同的ubuntu映像启动t1.micro实例（在us-west-2区域中提供）

Answer 1

正如@helloV所述，t1.micro已被禁用。您可以查看有关此特定ami的详细信息：

aws> ec2 describe-images --image-ids ami-d732f0b7 --region us-west-2
{
    "Images": [
        {
            "VirtualizationType": "hvm",
            "Name": "ubuntu/images/hvm-ssd/ubuntu-trusty-14.04-amd64-server-20160714",
            "Hypervisor": "xen",
            "SriovNetSupport": "simple",
            "ImageId": "ami-d732f0b7",
            "State": "available",
            "BlockDeviceMappings": [
                {
                    "DeviceName": "/dev/sda1",
                    "Ebs": {
                        "DeleteOnTermination": true,
                        "SnapshotId": "snap-47713105",
                        "VolumeSize": 8,
                        "VolumeType": "gp2",
                        "Encrypted": false
                    }
                },
                {
                    "DeviceName": "/dev/sdb",
                    "VirtualName": "ephemeral0"
                },
                {
                    "DeviceName": "/dev/sdc",
                    "VirtualName": "ephemeral1"
                }
            ],
            "Architecture": "x86_64",
            "ImageLocation": "099720109477/ubuntu/images/hvm-ssd/ubuntu-trusty-14.04-amd64-server-20160714",
            "RootDeviceType": "ebs",
            "OwnerId": "099720109477",
            "RootDeviceName": "/dev/sda1",
            "CreationDate": "2016-07-15T10:37:25.000Z",
            "Public": true,
            "ImageType": "machine"
        }
    ]
}

密钥为"VirtualizationType": "hvm"，因此此ami仅支持硬件虚拟机（HVM）虚拟化类型。

t1（和其他第一代AMI）实例支持半虚拟（PV）虚拟化。
