VirtualBox is a software package which allows you to run multiple operating systems simultaneously. VirtualBox runs on Mac OS X, Linux, and Windows host operating systems. Once installed on the host operating system, VirtualBox allows you to create virtual machines which emulate a standard x86 hardware environment in which most x86-based operating systems can be installed and run. You can test new operating systems without making any changes to your existing operating environment. VirtualBox's graphical user interface enhances the installing and removing of virtual machines.
Removing a Virtual Machine
Shut or power down the guest operating system you want to remove and leave VirtualBox running if you're currently running the guest operating system. Otherwise start up the VirtualBox application.
Click on "File," then "Virtual Media Manager." You can also reach the Virtual Media Manager by pressing "Control" and "D."
Highlight the virtual disk image you're removing while still in the Virtual Media Manager. Click on the "Remove" icon. Virtual Box will ask if you're sure you want to remove the hard disk. Click "Remove." VirtualBox will then warn you that deletions can't be undone. Click "Delete" to completely remove the virtual hard disk image. Click "OK" to close the Virtual Media Manager.
Click on the name of the virtual machine you're removing from the main VirtualBox program to highlight it. Click on the "Machine Menu" and then click on "Delete." VirtualBox will ask you to confirm that you want to permanently delete your virtual machine. Click on "Delete" to remove the virtual machine.
Tips & Warnings
- If you originally installed your virtual machine from an operating system image or ISO file you downloaded, you can recover disk space by using your file manager to locate and delete the image file. Empty your desktop's trash can to completely remove the file from your system.
- If you're certain you will not use the virtual disk images you created again, delete them in Virtual Machine Manager. If VDI's aren't deleted after they're detached, they remain on your hard drive. Virtual machines can sometimes be quite large.
