This commit replaces inline workflow preparation logic with a dedicated `solstice-bootstrap.sh` script, simplifying workspace setup, job execution, and shutdown processes. The change ensures cleaner orchestration and improves maintainability by centralizing the bootstrapping logic.
This commit enhances the `Scheduler` to monitor VM states for completion, enabling more accurate termination detection. It introduces periodic polling combined with shutdown signals to halt operations gracefully. Additionally, VM lifecycle management in the hypervisor is updated with `state` retrieval for precise status assessments. The VM domain configuration now includes serial console support.
This commit updates the `Scheduler` to support cooperative shutdown using `Notify`, allowing graceful termination of tasks and cleanup of placeholder VMs. Additionally, the AMQP consumer is enhanced with an explicit shutdown mechanism, ensuring proper resource cleanup, including closing channels and connections.
This commit introduces the ability to configure placeholder VM run time via an environment variable (`VM_PLACEHOLDER_RUN_SECS`) and updates the `Scheduler` to accept this duration. Additionally, it implements a graceful shutdown mechanism for the orchestrator, allowing cooperative shutdown of consumers and cleanup of resources.
This commit improves the hypervisor by:
- Adding support for detecting base image formats using `qemu-img info`.
- Dynamically setting the base image format for overlay creation.
- Automatically converting non-raw images to raw format for bhyve compatibility.
- Updating `Cargo.toml` to include `serde_json` for JSON parsing.
- Modifying default working directory logic for `ZonesHypervisor`.
This commit replaces the `libvirt` crate with the `virt` crate for managing the libvirt backend on Linux. Key changes include:
- Updated `Cargo.toml` dependencies and feature configuration.
- Refactored hypervisor implementation to align with `virt` crate API.
- Improved error handling and lifecycle management for VMs and networks.
This commit introduces a persistence layer to the Orchestrator, enabling it to optionally connect to a Postgres database for recording job and VM states. It includes:
- SeaORM integration with support for migrations from the migration crate.
- `Persist` module with methods for job and VM state upserts.
- No-op fallback when persistence is disabled or unavailable.
- Documentation updates and test coverage for persistence functionality.
