Broadcom Pulls VDDK Downloads, Making VMware Migration Harder

Leaving VMware just got harder after Broadcom pulled VDDK downloads

Broadcom has quietly removed public downloads of the VMware Virtual Disk Development Kit (VDDK), a library critical to many third-party migration tools. Microsoft, Red Hat, Nutanix, and Platform9 have all reported that customers can no longer access VDDK, with Broadcom support confirming it's no longer available for general use. This move complicates exits from VMware, though Proxmox's built-in import tool remains unaffected.

Trust is ultimately what is now gone from the platform.

    As an old ex-vmware eng it's kinda sad reading all these articles about broadcom's controlled descent into terrain. A lot of really cool and useful engineering was done in vmware's heyday, and it was often delivered in rather shaky commercial shapes, but for a while the whole thing kinda worked. And broadcom seems to see it as a company that is long past its ability to innovate, extracting as many dollars as possible before its rapidly decreasing value goes to zero.

    There was a solid few years that a lot of business types at vmware behaved as though winning was the default, assured state. It took several years for them to see that that was very much not the case. A real lesson in there, for every successful business today.

    I got my current job because I could lead the hyper-v to VMware migration project. Just this year I led the VMware to hyper-v migration project. VMware was such a great product (although a bit cumbersome in the VCF environment I managed). It’s really unfortunate it went the way of Broadcom. In comparison Hyper-v feels like a typical Microsoft product. A bunch of different tools created by different teams to do tasks that feel bolted on and afterthoughts. I have to run FCM to manage the nodes? But I run HVM to manage the roles? But there’s no overall resource management like VMware vsphere or proxmox does natively?

    I’ve quietly built a proxmox cluster in our environment for semi-prod workloads for when the inevitable windows host has issues.

    > VMware to Proxmox migrations are not affected ...

    Amusingly - and acknowledging tiny scale and modest automation requirements of home lab compared to enterprise - as I started migrating to Proxmox a year or two ago, the process of shuffling VMs off my ESXi servers and onto Proxmox was surprisingly painless. Effectively mount the ESXi as storage systems, and then 'copy to here'.

    IIRC the only small challenges were a conservative choice on target VM's CPU type (Proxmox seems to dislike defaulting to 'host' CPU) and the network / SCSI controller defaults. I assume designed to prioritise robustness over performance.

    All automatable, I'm sure.

    So the Linux qemu-img tool can still convert VM disk images from .vmdk into formats compatible with all the other hypervisors. Is there something more to the process of VM migration from VMWare than just using this tool (and manually creating the proper virtual hardware profile in the new hypervisor)?

    Obviously the types of supported virtual hardware will be different between hypervisor types, but that's usually something that can be dealt with separately.

    > I am of the school of thought that even if Broadcom gives VMware Standard away free for a year, it would be hard to convince customers that they need to stick with the platform

    Yep. They're building the cage around you. Why would you stick around?
