Containers storage technologies are changing rapidly. Volume Plugins in Docker and Kubernetes open doors to 3rd party storage provisioning for containers. However, these technologies are all based on bind-mount, volume drivers have to implement storage functionalities on their own.

On the other hand, QEMU has a different approach to provide storage for virtual machines. QEMU's block drivers abstracts different backend storage types and thus supports features like multi-tenancy, snapshot, and QoS, which are currently missing in Container storage drivers.

This talk presents a new technology that converges QEMU and TCMU. This allows Containers to use rich storage features that are already available to Virtual Machines. This technology integrates QEMU's block layer with tcmu-runner, and enables Containers to access various storage backends and rich storage features.
