AWS: Unable to Launch an Instance from Image created from snapshot

Question

Steps:

   1. Create a Snapshot from one of my GP2
   2. Click on Snapshots , select the above snapshot and Click Actions -> Create Image to create Images
   3. Click on AMIs and select the above image and Click "Launch"

Landed on Step 2 - Choose an Instance Type. But there are no types available. No valid instance types found. Neither able to click "Review And Launch"

What am I doing wrong?

PS: I can create image from EC2 instance and then able to Launch an instance (shows all types) successfully on that image

Answer 1

The problem here is that when you create an Image (AMI) from a EBS snapshot, the default virtualisation type is Paravirtual. However, all the instance types that I have checked, require Hardware-assisted Virtualisation.

So if you click on the Virtualization type drop down box and select Hardware-assisted Virtualisation as below, then all the types will then be available when you launch an instance from the ami.
