EC2在私有子網上啓動失敗

Question

我購買了保留的實例小時數，並且無法在我的私有子網中啓動保留實例。我得到的唯一信息是

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

如何解決此問題？該消息是無益的。

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. 

這裏是我的情況下推出的審查：

Answer 1

Tenancy     dedicated 

不要選擇。這對於專用主機。由於t2類型實例在專用主機上不可用，因此拋出錯誤。但是你寫了你有一個保留實例（RI）。所以你不想與專門的租戶一起推出。
