Broadcom Quietly 404s the VDDK Downloads, Removing the Library Every VMware Exit Tool Depends On

Broadcom removed the public download pages for the Virtual Disk Development Kit without an announcement around 2026-08-25, and support told customers it is "no longer available for use or download," redirecting them to authorized Technology Alliance Partners. VDDK is the dependency underneath Microsoft Azure Migrate, Red Hat's Migration Toolkit for Virtualization, Nutanix Move, Platform9 vJailbreak, and virt-v2v/nbdkit; Platform9 went public with the restriction on 2026-09-01 and Red Hat says it cannot redistribute the proprietary blob and is hunting alternatives. Proxmox's built-in importer is the one unaffected path because it never used VDDK, which is now a concrete architectural argument for how migration tooling should be built.
