Comment 53 for bug 1874453

@jchittum, thanks for the fix. I validated it and it seemed to work.

I came into a related issue however - I've created an image that is based on ubuntu/focal64 on a Linux system. When trying to use it on a Windows system, I got the following error:

```
Stderr: VBoxManage.exe: error: RawFile#0 failed to create the raw output file /dev/null (VERR_PATH_NOT_FOUND)

```

I believe that Ruby's File::NULL constant is translated into /dev/null when utilizing the focal64 image on Linux, and then it gets written into the resulting .ovf file.
