Why does my custom Amazon EC2 AMI have limited instance type options?
- by John
The Basic 64-bit Amazon Linux AMI has the following instance type options available:
Micro
Large
Extra-Large
High-Memory Extra Large
... etc
I booted up this AMI as a micro type, made customizations, shut it down, detached the volume, took a snapshot, and registered my own custom AMI:
ec2-register –snapshot [snapshot_id] –description "my description" –name "my name" –kernel aki-427d952b
That worked. HOWEVER, when I try to create an instance from my custom AMI, only the following instance types are available:
Micro
Small
High-CPU Medium
... which coincidentally are the same instance types available if you try to boot up the 32-bit Amazon image.
Why are the available instance types of my custom image varying from the available instance types of the image I based it off of?
