Unfortunately, the power supply of the external physical hard disk was switched off during work with virtualbox. Of course, the guest operating system crashes as a result. I restarted the system and also connected the external hard disk to the system. However, the Virtual box main window shows for all guests Could not lock the settings file '/Volumes/Machines/Machines/Windows_XP_Professional_32bit/Windows_XP_Professional_32bit.xml' (VERR_FILE_NOT_FOUND). I don't know what to do to solve the problem. Please support me. I am using Mac OS X Leopard as host." defect closed virtual disk VirtualBox 3.0.6 fixed Windows Mac OS X
