Hi@akhtar,

Docker takes advantage of containers and file system technologies in a high-level which are not generic enough to be managed by libvirt.

• Process-level API: Docker can collect the standard outputs and inputs of the process running in each container for logging or direct interaction, it allows blocking on a container until it exits, setting its environment, and other process-oriented primitives which don’t fit well in libvirt’s abstraction.

• Advanced change control at the file system level: Every change made on the file system is managed through a set of layers which can be snapshotted, rolled back, diff-ed etc.

• Image portability: The state of any docker container can be optionally committed as an image and shared through a central image registry Docker images are designed to be portable across infrastructures, so they are a great building block for hybrid cloud scenarios.

• Build facility: docker can automate the assembly of a container from an application’s source code. This gives developers an easy way to deploy payloads to an OpenStack cluster as part of their development workflow.

Hope this will help you.

Thank You
