Cloud-init is also available on RHEL systems too. We're using it extensively to contextualise VMs on Scientific Linux.
We've even tried a windows version but this is not as functional.

Atul is describing a different feature that can be used to achieve similar results. The contents of "User-Data" will be accessible to the instance via "http://169.254.169.254/latest/user-data"; - Ubuntu ships with a tool called cloud-init that makes use of this data if available. Eg One of the simple use cases for cloud-init is, if the data starts with "#!", it will assume it's a shell script and download + execute it. This can, in a roundabout way, be used to achieve similar results to the file injection feature.

I will select a file to inject from Horizon and Launch the Instance, it should inject that file. Regards, Srikanth.

Got image from http://cloud-images.ubuntu.com/precise/current/precise-server-cloudimg-i386- disk1.img 2. Booted it from Horizon and passed the script in the file #!/bin/sh mkdir /home/ubuntu/testdir 3. Logged in to the machine with ssh -i <mykey.pub> ubuntu@IP And i can see the directory created. File injection via Horizon uses cloud-init and i have tested it on Ubuntu 12.04 i have no idea about other distributions. You can file more about cloud-init here :- https://help.ubuntu.com/community/CloudInit And thanks, i will add this in the doc somewhere. :) Hope it helps.

Can File Injection can be done through Horizon, while creating an Instance? While creating an Instance from Horizon, a field called 'User Data' [text area] is there. Is that field is related to File Injection? Can anyone tell me, the values we need to give for 'User Data'? </snip> Yes. Cheers!!
