Hi Socratis,

Most of the times it gets deleted (if the controller is set to AC97). It doesn't happen if the version is 1.12 or 1.15.

See https://www.virtualbox.org/ticket/15626 - it's a 5.1.0 regression.

It would only help if you stick to 5.1.0, and a certain percentage of 
the users would edit the files while VirtualBox is running, no matter 
how often you repeat that it's a bad idea otherwise.

The next test build will have the fix (and any 5.1 build later than 
r108825). I hope that tomorrow we have enough time to update the test 


P.S.: Host OS is irrelevant :D
