Inside Capsule

Repeatable virtual machines

QEMU-backed machines and cloud-init provide a consistent starting point for local Linux environments.

Managed access and lifecycle

Machine lifecycle operations and managed SSH access bring local development environments into a command-line workflow.

Snapshots and portable archives

Snapshots, cloning, and archives support preserving an environment and transferring it between machines.

How it works

  1. Prepare QEMU and a compatible Linux guest image.
  2. Create a local machine with cloud-init and connect through managed SSH access.
  3. Preserve or transfer the environment using snapshots, cloning, and archives.

Project status

Capsule works with local QEMU virtual machines and requires QEMU and compatible Linux guest images. For availability, documentation, or collaboration, contact Centrion.
