I use VirtualBox all the time for testing OM Lx all versions. I do not use DVD’s, I use the .iso file. (Select the Folder next to the line where is says “Host Drive”). This is faster because you no longer need to burn DVD and the system will be faster unless you have a hard drive that is as slow as a DVD reader which is not likely.

My DVD’s are covered with dust since I have not burned one in forever it seems.
