tl;dr: Broadcom has quietly removed public downloads for VMware's Virtual Disk Development Kit (VDDK), a library that underpins migration tools from Microsoft Azure Migrate, Red Hat MTV, Nutanix Move, Platform9's vJailbreak, and virt-v2v. Support has reportedly confirmed the removal is intentional, with access now restricted to Broadcom Technology Alliance Partners, forcing customers into agent-based migrations or storage-assisted workarounds. Proxmox migrations are unaffected since its built-in import tool doesn't rely on VDDK, but the timing—coinciding with the return of vSphere Standard—looks to many like a lock-in tactic against customers leaving the platform.
