VirtualBox

source: vbox/trunk/src/VBox/Main/include/VirtualBoxImpl.h@ 37596

Last change on this file since 37596 was 37525, checked in by vboxsync, 14 years ago

Main/VirtualBox+Medium: resurrect the feature of changing the medium UUID when opening the image, which allows to resolve duplicate UUIDs without using external tools. Also fixes Medium::setIDs, which wasn't correctly working.
