So, just a quick update.

I downloaded an older version of V2V (9.0.1.268) that I found a link to on another post, and it appears to have worked.

Howdy. I'm attempting to convert some ESXi VMs to XCP-NG, and the easiest way for me to do that would be to convert the VM hard drives to VHD format and import them on the XCP-NG machine. However, every time I try to run the V2V conversion, it dies. No error message, the snapshot file is left behind...
