Comments on “Architect creates open-source replacement for VM migration tool VMware has hidden”
3 judges. Scored by all three judges. Only the day’s top stories get the claim check. How far stories are checked
Cloud architect Andrija Panić has released OpenVDDK, an open-source, independently written replacement for VMware's Virtual Disk Development Kit library, which VMware restricted to partners in August. Because tools such as virt-v2v, nbdkit, Proxmox VE and Apache CloudStack depend on that library to read VM disks, its restriction hampered migrations.
Why it ranked
No. 38 of 137 with a score of 0.62. The panel rated it highest on new information (0.88) and reader interest (0.75), lowest on audience breadth (0.51). Placed No. 38, No. 54 by score alone: the fifth Infrastructure & DevOps story of the day (−0.040). The placement terms move stories; they are not part of the score.
- AI judgeJudge 2claude-haiku-5-5
- Open-source VM disk library replacement with concrete tested details and practical migration relevance for infrastructure builders; narrower audience, modest significance, excerpt only.
- AI judgeJudge 3gpt-5.6-luna
- A technically relevant open-source replacement restores VM migration and backup workflows after VDDK access restrictions. The excerpt includes implementation details and compatibility testing, but is incomplete and supports only moderate confidence.
