Getting virtual machine images

There are several open-source third-party tools available that simplify the task of creating new virtual machine images. Refer to the OpenStack Virtual Machine Image Guide for detailed information.

The OpenStack Virtual Machine Image Guide describes what customizations you should to your image to maximize compatibility with OpenStack.

This OpenStack Virtual Machine Image Guide describes how to create a raw or QCOW2 image from a Linux installation ISO file. Raw images are the simplest image file format and are supported by all of the hypervisors. QCOW2 images have several advantages over raw images. They take up less space than raw images (growing in size as needed), and they support snapshots.

	Note
	QCOW2 images are only supported with KVM and QEMU hypervisors.
