Cloudformation 模板给出了“此实例类型当前不支持虚拟化类型为 'hvm' 的非 Windows 实例

Question

我写了一个简单的 cloudformation 模板，它应该在 AWS 上创建一个 EC2 实例。

Cloudformation 模板给出“此实例类型目前不支持虚拟化类型为 'hvm' 的非 Windows 实例。”我在这个论坛上查了一下，他们说 "InstanceType" 不见了。我是 Cloud formation 的新手。我应该把"InstanceTyp"放在哪里？非常感谢 { "AWSTemplateFormatVersion" : "2010-09-09",

我看到您没有在 CF 中指定实例类型。默认类型为 m3.medium。看起来您正在使用的区域 m3.medium 不支持 hvm 类型的 AMI。

指定实例类型的一种方法：EC2 Instance Type Parameter

Cloudformation 模板给出了“此实例类型当前不支持虚拟化类型为 'hvm' 的非 Windows 实例

Cloudformation template gives " Non-Windows instances with a virtualization type of 'hvm' are currently not supported for this instance type
