Cloud virtual machines available for free for open source testing? [closed]

Question

Anyone know about places in the cloud where you can create (virtual) machines (like Amazon EC2) to use for your computing tasks - places that offer a number (at least 5-10) of free machines, if they are used for testing open source projects?
