3 Configuring virtual machines Enable 2D video acceleration If a virtual machine with Microsoft Windows has Guest Addi- tions installed, you can select here whether the guest should support accelerated 2D video graphics. Please refer to chapter 4.4.2, Hardware 2D video acceleration for Windows guests, page 65 for details. Remote display Under the “Remote display” tab, if the VirtualBox Remote Display Extension (VRDE) is installed, you can enable the VRDP server that is built into VirtualBox. This allows you to connect to the virtual machine remotely with any standard RDP viewer, such as mstsc.exe that comes with Microsoft Windows or, on Linux systems, the standard open- source rdesktop program. These features are described in detail in chapter 7.1, Remote display (VRDP support), page 90. 3.6 Storage settings The “Storage” category in the VM settings allows you to connect virtual hard disk, CD/DVD and floppy images and drives to your virtual machine. In a real PC, so-called “storage controllers” connect physical disk drives to the rest of the com- puter. Similarly, VirtualBox presents virtual storage controllers to a virtual machine. Under each controller, the virtual devices (hard disks, CD/DVD or floppy drives) attached to the controller are shown. Note: This section can only give you a quick introduction to the VirtualBox storage settings. Since VirtualBox gives you an enormous wealth of options in this area, we have dedicated an entire chapter of this User Manual to explaining all the details: please see chapter 5, Virtual storage, page 71. If you have used the “Create VM” wizard to create a machine, you will normally see something like the following: Depending on the guest operating system type that you selected when you created the VM, the typical layout of storage devices in a new VM is as follows: • You will see an IDE controller, to which a virtual CD/DVD drive has been attached (to the “secondary master” port of the IDE controller). 46
