Virtual Box - Immutable Disk not working...

[kennysarmy]

I have a windows 7 image - the storage settings says it's "Immutable (VDI)" but I can make changes to the desktop etc which remain after I reboot.

 

What can I check?

Check you don't have save state enabled (aka differencing disk cache) for when closing machines. Else it'll create a seperate folder that holds your "changes" in, then will reload them on top of the immutable drive.

I think there were some child objects under the VDI Name (in Virtual Media Manager) which was somehow causing the changes to remain.

 

I deleted the VDI and broke the link to my VM then recovered the VDI file from a copy I'd made and now all is working as it should.
