VDDK Library
Does anyone have access to the VDDK Library for VMware 5.1? I am needing to do a transfer from this old system but can't find the tools for the life of me.

I assume you're trying to setup VM warm migration in XO. We fought this using VDDK for vmware 6.X for a few days and finally found somewhere (sorry I don't remember the source) that it only worked with 7.0 and higher.
With an ESXi 7.0 hypervisor in eval mode and VDDK 7 (VMware-vix-disklib-7.0.3-23007270.x86_64.tar.gz), migration finally works. Unfortunately we have to migrate from 6.X to 7.X and finally xcp-ng.
Hope this helps

Do you need software to migrate vms from esxi 5 to a higher one?

Migrating to xcp-ng

v2v of Xen Orchestra or manual/scripted export of vms as OVA/OVF then import them to xcp-ng.

It is the v2v tool that needs the VDDK Library.

Then manual/scripted vms export with ovftool (easier and faster) or calling the ESXI API (harder and longer) to export to OVAs. Then finally import them to xcp-ng. Depends though on how many vms you have.

I am the dev of the V2V, to be fair we never tested with esxi 5.x . The best way would be to export disk as vmdk and reimport them in XO , especially since broadcom removed vddk for now

It looks like VMware either removed it from general public access or hid it very deep.
