Guest OS: openSUSE 11.0 When trying to start a VM with CD ISO inserted, it gave me very strange error about the PIIX3 IDE controller, while the reality, is that I have used PIIX4 controller. The real reason for this error, is because other program on my Windows host used read file lock on the ISO file. Every other Windows program, be it Nero, Notepad or MS VirtualPC reported the correct error message - ""This file is locked by other Windows process""... VirtualBox displayed incorrect Error message. ""PIIX3 IDE controller error"" As soon as I killed the other process, that locked the file (it was old bittorrent client, that I used to download ISO in first place), Vbox started fine. Would be nice to fix the error message dialog, even through this situation is rare to happen. -Technologov, 27.6.2008." defect closed virtual disk VirtualBox 1.6.2 fixed other other
