New separate GUI / VMM mode
Posted: 2. Apr 2015, 12:16
We forgot to mention an important new feature of VirtualBox 5.0 in the changelog: The separate GUI mode. Just try it out:
Q Why is this mode not default?
A It causes some performance impact for graphics output. In fact there is a VBoxHeadless VM process in the background and the GUI process. For graphics output both need to communicate. 2D acceleration does not work currently. 3D acceleration might not work, it depends on the host and how the VM process was started i.e. as headless or as separate from the GUI.
Q Why do I need to specify command line parameters, is there no GUI function?
A to be implemented.
- Start a VM from the command line like this:
Code: Select all
VirtualBox --startvm VM_NAME --separate
- Open the Close VM dialog
- Select Continue running in the background and press OK
Code: Select all
VirtualBox --startvm VM_NAME --separate
