QCOW2 is a sparse disk image format made popular by the QEMU emulator and virtualizer. Ceph RBD has its own native storage format and supports exporting its own native disk image format. However, many image ecosystems are built around the QCOW2 format, making it advantageous to use the QCOW2 image format in an external image repository for compatibility as well as advanced features. In this talk we discuss how to enable export and live migration in Ceph of sparse QCOW2 differential images using the Network Block Device, NBD, protocol. As well, we describe future changes to enable native support of the NBD protocol in Ceph in order to facilitate easier adoption of the QCOW2 format with Ceph.
