the wrong way to create image from sanpshot

If you create a EC2 image from the the sanshot which is a wrong way, you will end up with below error message:

EXT3-fs: sda1: couldn't mount because of unsupported optional features (240).
EXT2-fs: sda1: couldn't mount because of unsupported optional features (244).
Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(8,1)

The wrong way is:

1. Create sanpshot from the running instance volume

2. Click the created snapshot and create image from the snapshot

3. Launch instance with the created image

The correct way is:

1. Create image from the running instance

2. Launch instance with the created image

That's it!
