The format of the Fedora CoreOS Nutanix image will change  in the next release of the
Fedora CoreOS `next` and `testing` streams. Current releases ship the Nutanix image as a
qcow2 file wrapped with xz compression (`qcow2.xz`). Future releases will switch to a
qcow2 file without any wrapper (`qcow2`), internally compressed with qcow2's built-in
compression support. Following the usual release schedule, this change will promote to the
`stable` stream two weeks after the `next` and `testing` releases.
We are making this change to support direct uploading of Fedora CoreOS images into Nutanix
AHV using the Nutanix Prism API. This allows users to avoid manually downloading,
decompressing, and re-uploading Fedora CoreOS images when adding them to Nutanix Prism
If you use the Nutanix image, you will need to adjust your workflow  for adding Fedora
CoreOS images to Nutanix AHV. If you do not use the Nutanix image, this change will not
If you have any questions or concerns, or expect this change to break a critical workflow,
