The list shall be list of direct URLs to images, followed by hash (#), then by image MD5SUM. Each image shall appear on newline, like: "https://example.com/image.iso#06226c7fac5bacfa385872a19bb99684<newline>https://example.com/another-image.iso#31b40d58b18e038498ddb46caea1361c". They will be provided in KVM image list according to the order on the list. After updating the list, the instance has to be restarted to refresh it. Amount of images is limited to 4, and one image can be maximum 10G. Image will be downloaded and checked against its MD5SUM 4 times, then it will be considered as impossible to download with given MD5SUM. Each image has to be downloaded in time shorter than 4 hours, so in case of very slow images to access, it can take up to 16 hours to download all of them. Note: The instance has to be restarted in order to update the list of available images in the VM. Note: Maximum 3 ISOs are supported.
If you want to have a Windows OS, you will also need to add virtio-win from https://fedorapeople.org/groups/virt/virtio-win/direct-downloads/archive-virtio/.
In order to get MD5SUM of an image, you can find some tutorials online.
