.XML-PREV Extension de fichier

VM VirtualBox is a virtualization app that allows users to create and run virtual machines. For example, a Linux user might use VM VirtualBox to run a Windows virtual machine within Linux.

At startup, VM VirtualBox loads application-wide settings from an .XML file named VirtualBox.xml. If VM VirtualBox cannot find or load settings from VirtualBox.xml, it will not launch.

For this reason, VM VirtualBox maintains a backup copy of your most-recent application settings in a file named VirtualBox.xml-prev. This file is stored alongside VirtualBox.xml, in the VirtualBox directory.

How to replace VirtualBox.xml with VirtualBox.xml-prev

If your copy of VirtualBox.xml goes missing or becomes corrupted, you can replace the file with your copy of VirtualBox.xml-prev, to attempt to restore your VM VirtualBox settings. To do so:

1. Go to the VirtualBox directory.
2. If you still possess VirtualBox.xml, rename it to VirtualBox.xml-bad (or any other new filename).
3. Rename your copy of VirtualBox.xml-prev to VirtualBox.xml.
4. Attempt to open VM VirtualBox as you would normally.

If your new VirtualBox.xml file contains valid settings, VM VirtualBox should run as normal.

REMARQUE: XML-PREV files are similar to the .VBOX-PREV files VM VirtualBox uses to back up individual virtual machine settings.

If necessary, you can open an XML-PREV file with Microsoft Visual Studio Code or any other text editor, to view the settings it contains. For instructions on how to use XML-PREV files with Oracle VM VirtualBox, see the How to replace VirtualBox.xml with VirtualBox.xml-prev section above.
