私有子网上的 EC2 启动失败

Question

我已购买预留实例小时数，但无法在私有子网中启动预留实例。我收到的唯一消息是

Launch Failed
The requested configuration is currently not supported. Please check the documentation for supported configurations.

如何对此进行故障排除？该消息没有帮助。

What I have done:
1. Created two subnets. One public (10.0.0.0/25) and one private (10.0.1.0/25).
2. Assign route tables to each subnet. The public subnet is attached to an Internet Gateway.

以下是对我的实例启动的评论：

Answer 1

Tenancy                 dedicated

不要选择那个。这是为专用主机准备的。引发此错误的原因是 t2 类型实例在专用主机上不可用。但是你写你有一个预留实例 (RI(。因此，您不想使用专用租赁启动。
