Explain what you mean by âtrying to upload the hosts automaticallyâ. They should NOT do anything with the fog server automatically, other than load the pxe boot IF you have enabled the options in the BIOS. If you have sent commands to the Host after registering it and telling it to upload/image and it continues to try to image after completion, the job did not delete the file when the job was done. This can be done manually and I will explain if you would like, there are some posts on the forum if you would like to research yourself though.
I noticed the issues with the /opt/fog/service/etc/config.php too. I had to add the database user, host, and database manually. Not sure why.

Good luck on 13.10, I got it working and running after the hurdles, but I have found that if you have older hardware, 13.10 doesnât tend to to enjoy it. You should be fine operating a VM though.
