- Introduced a new method `installed_kernel` in `ImageStore` to handle kernel verification and checksum validation. - Updated `Installer` to include additional packages: `nftables` and `conntrack`. - Refined `LifecycleService` to improve error handling and state management during VM creation, starting, stopping, and deletion. - Enhanced port management with new methods for setting and syncing ports, including validation for port rules. - Improved error handling in `StateStore` to raise specific `NotFoundError` and `ConflictError` exceptions. - Updated network management to ensure proper TAP device handling and firewall integration. - Enhanced API responses in `vms.py` to include policy status for better client-side handling. - Added validation for VM names and ports in `validation.py` to enforce stricter rules and prevent conflicts.
