如何更改amazon ec2中的实例类型

目前我有m3.xlarge实例类型,但我想将其更改为t1.micro.我已停止服务器并尝试instace type通过右键单击实例名称来更改.

但是,当我单击"提交"以更改服务器名称时,我在控制台中收到错误:

POST https://console.aws.amazon.com/ec2/modify-instance-attribute 400 (Bad Request) 

当我详细说明它进入网络时,我从服务器得到的响应是:

{"errors":[{"service":"AmazonEC2","action":"ModifyInstanceAttribute","endPoint":"https://ec2.us-east-1.amazonaws.com","statusCode":400,"message":"Non-Windows instances with a virtualization type of 'hvm' are currently not supported for this instance type.","errorCode":"InvalidParameterCombination","errorType":"Unknown","requestId":"28025a27-4c3c-452c-8f04-fc4adc8eb335","serviceResponse":{"Response":{"Errors":{"Error":{"Code":"InvalidParameterCombination","Message":"Non-Windows instances with a virtualization type of 'hvm' are currently not supported for this instance type."}},"RequestID":"28025a27-4c3c-452c-8f04-fc4adc8eb335"}}}],"error":"Non-Windows instances with a virtualization type of 'hvm' are currently not supported for this instance type."}

如何解决此问题,或者如何将实例更改xlarge为micro

无论出于何种原因,亚马逊的基于HVM的AMI与t1.micro大小不兼容.

亚马逊拥有基于硬件虚拟机(HVM)的AMI和基于半虚拟机(PVM)的AMI.从该错误消息中,AWS表示您当前的实例是基于HVM的,而t1.micro大小仅支持基于PVM的实例.

这样做的方法是从您的实例创建一个新的AMI,并从该AMI启动一个新的实例作为t1.micro大小.但是要小心,这可能只是创建一个基于HVM的AMI,在这种情况下,您需要为当前实例的卷创建快照并从中创建一个新的AMI.

有趣的是,昨天推出的新t2系列取代了t1和部分m1系列,仅支持HVM.亚马逊称,由于更好的驱动程序,HVM性能现在超过了PV性能.http://aws.amazon.com/blogs/aws/low-cost-burstable-ec2-instances/

"...快照当前实例的卷并从中创建一个新的AMI".有没有人成功完成这个？我尝试了相反的方向:使用我的PVM快照(想要从t1迁移到t2)创建一个新的基于HVM的AMI,但是我创建的HVM实例无法启动.记录[此处](https://serverfault.com/questions/615188/aws-t1-to-t2-migration-client-instanceinitiatedshutdown-on-new-t2-instance).如果有人这样做了,我会喜欢一些分步说明!
