VMware Converter ‘A file I/O Error Occurred’

KB ID 0001688

Problem

It seems every time I use VMware Converter, there’s some new error that jumps up and makes me stumble!

Yesterday the problem was;

FAILED: A file I/O error occurred while accessing

VMWare Converter Error IO

Solution

Some searching told me this is actually a DNS problem, (where the converter could not resolve the DNS name of the machine being converted). BUT I had put the FQDN directly into this machines ‘hosts file’ so I doubt that was my problem. I suspect it was the fact that this machine was presenting a certificate that wasn’t trusted was actually the problem.

But either way the way to fix it is to re-queue the job again, but this time choose “Use proxy mode“.

Then it worked fine.

  1. Hi, I had this problem and it turned out to be the esxi firewall. The proxy node was in the allowed list for port 902 but the source server wasn’t. Once I added the source, it was fixed.
