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!

chrome java plugin on windows 7 64 bit


Chrome and Firefox on windows 7 64 bit OS both are only support 32 bit application.

Therefore, if you want to install java plugin in Firefox and Chrome, you need to install java jre 32 bit version instead of 64 bit.

Another thing is if after jave jre installation, in java testing page, you still keep asking to install jave plugin, it might caused by some chrome plugins blocks the jave plugin installation. you can use "about:plugins" to disable some plugin or in extension page remove some extenstions.
