“c4.2xlarge”类型的实例需要虚拟化类型“hvm”

Question

我是初学者。

尝试使用 com.amazonaws.services.ec2.model.RunInstancesRequest 亚马逊服务启动 EC2 实例 (c4.2xlarge) 时。

我收到以下错误。

2016-05-23 13:13:19 ERROR org.codehaus.groovy.grails.web.errors.GrailsExceptionResolver: 213 - AmazonServiceException occurred when processing request: [POST] /leaseabuse-crawler-manager/instances/start
Virtualization type 'hvm' is required for instances of type 'c4.2xlarge'. Ensure that you are using an AMI with virtualization type 'hvm'.

下面是我尝试使用的代码

RunInstancesRequest runInstancesRequest = new RunInstancesRequest()
                .withInstanceType(InstanceType.C42xlarge)
                .withImageId(amiId)
                .withMinCount(count)
                .withMaxCount(count)
                .withSecurityGroupIds("some-group")
                .withKeyName("Key-name")

谁能建议我哪里出错了。 请帮忙出来。

Linux Amazon 系统映像使用两种虚拟化类型之一：半虚拟化 (PV) 或硬件虚拟机 (HVM)。 PV 和 HVM AMI 之间的主要区别在于它们的启动方式以及它们是否可以利用特殊的硬件扩展（CPU、网络和存储）来获得更好的性能。

为获得最佳性能，我们建议您在启动实例时使用当前一代的实例类型和 HVM AMI。

您使用的 AMI ID 是半虚拟的，因此只能在 older generations of EC2 instances 上运行。
