AKI, or *Amazon Kernel Image*, are a specific type of image. It represents the Xen guest para-virtualized kernel, as used by an AMI. Certain AKIs are allowed to boot customized operating systems, e.g. those that are still not officially supported by Amazon. Thanks to [PyGrub](http://wiki.xensource.com/xenwiki/PyGrub), it can boot a kernel that resides inside an AMI's snapshot. |

(For the future) Once NetBSD has decent support for Amazon EC2, we will publish the AMI identifiers so you can quickly boot up in a NetBSD environment without going through all the steps given below. |

## Upload your OS |
# Upload NetBSD to EC2 |

We must now upload our NetBSD system to EC2. For that, we will have to create a minimalist EC2 instance, to which we will copy our files to construct our snapshots. For that, we will use an Amazon Linux AMI instance. |

EC2 being localized in geographical regions, you have to carefully choose the AMI identifier you want to use there. This depends on where you want to execute your instance. Amazon Linux AMI IDs are listed on [the main page](http://aws.amazon.com/amazon-linux-ami/) of the project, by regions. Chose ones backed by EBS. |

### Creating the instance |
## Create an Amazon Linux instance |
|
|
Creating an instance straightforward. Amazon provides [different types of instances](http://aws.amazon.com/ec2/pricing/), with varying levels of billing and reliability. We will use a [*micro* instance](http://aws.amazon.com/ec2/faqs/#How_much_compute_power_do_Micro_instances_provide); its pricing is almost free. |
