For example, VBOX_DISABLE_HOST_DISK_CACHE=1. The short form of this option is -E. --type=gui | headless | sdl | separate Specifies the frontend used to start the VM. You can use the VBoxManage setproperty command to set a global default value for the frontend. Alternatively, you can use the VBoxManage modifyvm command to specify a default frontend value for a specific VM. If neither a global or per-VM default value is set and you do not specify the --type option, then the VM opens in a window on the host desktop. The --type option accepts the following values: gui Starts a VM in a graphical user interface (GUI) window. This is the default. headless Starts a VM for remote display only. sdl Starts a VM using the VBoxSDL frontend. separate Starts a VM with a detachable user interface (UI), which means that the VM runs headless with the UI in a separate process. This is an experimental feature that lacks certain functionality, such as 3D acceleration. If a VM fails to start with a particular frontend and the error information is inconclusive, consider starting the VM directly by running the frontend. This workaround might provide additional error information. The following command starts the ol7u6 VM: $ VBoxManage startvm ol7u6 The following command starts the ol7u6-mininstall VM in headless mode. $ VBoxManage startvm ol7u6-mininstall --type headless , , .
