This talk gives an overview of GlusterFS for scale-out storage management of KVM disk images. GlusterFS creates network attached storage on commodity hardware, including features for elastically adding/removing nodes and georeplication. Recent improvements in GlusterFS and KVM make it easy to run VM disk images on GlusterFS volumes. We also focus on GlusterFS architecture and how it could be extended for virtualization-specific needs.

Previous experience with KVM or GlusterFS is not necessary, but a general understanding of virtualization and disk images is required. Users of NFS and iSCSI may be particularly interested in this talk to see how GlusterFS approaches networked storage differently and is uniquely flexible.
