Mar 1, 2026March 2026 achievements in kubev2v/forklift focused on making migrations more deterministic, safer, and resource-conscious across VMware and libvirt environments. Delivered VM-level control for shared disk migration, explicit boot disk detection, and manifest exposure of the detected boot disk index; established per-VM overrides to migrate shared disks and refined resolution logic. Implemented deterministic disk ordering for VMware disks to align with libvirt expectations, and ensured consistent disk ordering in the virt-v2v container. Added RDM-as-LUN support to improve SCSI/SGIO compatibility during migration, enabling SGIO commands for direct-attached disks. Enabled per-plan and per-VM control of nested virtualization to optimize Windows guest performance (e.g., VBS scenarios). Introduced VM-level resource sizing for virt-v2v (memsize and SMP) to better match migration workloads. These changes reduce migration risk, improve compatibility with storage offload, and enable finer-grained performance tuning for complex workloads.

Dec 1, 2025Monthly summary for 2025-12 focusing on kubev2v/forklift contributions. Delivered features and fixes that broaden migration compatibility, improve accuracy, and increase deployment flexibility, while reducing maintenance overhead and aligning with modern kernel environments. Business value delivered includes lower migration failure rates, smoother upgrades with updated OS mappings, and greater operational agility through VDDK-free storage offload. Key achievements (business value oriented): - Expanded vsphere OS map for VMware migrations (MTV-3632), removing minor versioning to simplify updates and increase compatibility with latest kubevirt releases. - Migration progress accuracy fix (MTV-2099), ensuring completion status reflects successful pod conversions and disk task progress for reliable migration outcomes. - V2V containerfile and filesystem support modernization (MTV-4068; removal of upstream fssupport) to enable XFSv4, compatibility with newer kernels, and CentOS 9-based environments. - Storage offload without VDDK support (MTV-4061), enabling offload workflows without VDDK and increasing migration flexibility. Overall impact and accomplishments: - Improved migration reliability and coverage through expanded OS mapping and accurate progress reporting. - Reduced maintenance burden by removing minor-versioning in OS maps and deprecated fssupport containerfile. - Enabled up-to-date kernel compatibility and safer migration environments via CentOS 9-based v2v container and XFSv4 support. - Enhanced operational flexibility with VDDK-free storage offload, expanding deployment scenarios. Technologies/skills demonstrated: - VMware vSphere OS mapping, containerfile orchestration, libguestfs integration considerations, and kernel compatibility planning. - Go-based tooling interactions, code review discipline, and commit-level traceability (MTV IDs) for governance and auditability. - Validation logic adjustments and task progress tracking for end-to-end migration lifecycle accuracy.
