Why it should not be possible to remove a machine?

There is a number of machines in the list that are 'Inaccessible' as their files have been removed with removable hard drives.
I cannot delete them from the list. Why is the product designed to not allow that?

You can actually edit the VirtualBox.xml to fix this but back the original up first.

You are right. Convenience is unnatural.

And knowledge is rare.
