Hello,

I am looking into booting a virtualbox VM using an external .iso. In order to do that I am currently working on a simple setup where I just have the necessary drivers and the VFS. I am trying to see if everything is working using "fs-query" but I get an error in the <rump> node saying "Mounting 'cd9660' file system failed (22)". I also tried the same setup with a "vfs" node instead of "fs-query", having the same error. I know the configuration contains a lot of redundant information but I am still learning. :)
Looking forward if anyone has any advice on how to fix this.

Thank you!

This is my run file. "test.iso" is a tinycore installer.
