On a Windows host, this will be a name like COM1. Host Device: Connects the virtual serial port to a physical serial port on your host. How this virtual serial port is then connected to the host is configurable, and the details depend on your host OS. Both receiving and transmitting data is supported. Other UART types can be configured using the VBoxManage modifyvm command. If a virtual serial port is enabled, the guest OS sees a standard 16550A compatible UART device. With virtual serial ports, system programmers can do kernel debugging on a virtual machine instead of needing a real computer to connect to. Also, serial ports are indispensable for system programmers needing to do kernel debugging, since kernel debugging software usually interacts with developers over a serial port. For example, serial ports can be used to set up a primitive network over a null-modem cable, in case Ethernet is not available. While serial ports are no longer as common as they used to be, there are still some important uses left for them. Serial ports were commonly used with modems, and some computer mice used to be connected to serial ports before USB became commonplace. The following options are available:Įver since the original IBM PC, personal computers have been equipped with one or two serial ports, also called COM ports by DOS and Windows. You could also add a second virtual CD/DVD drive, or change where these items are attached. For example, if you wish to copy some files from another virtual disk that you created, you can connect that disk as a second hard disk, as in the above screenshot. You can modify these media attachments freely. Each is represented by a disk image file, such as a VDI file in this example. Initially you will normally have one such virtual disk, but as shown in the previous screenshot, you can have more than one. This is a modern type of storage controller for higher hard disk data throughput, to which the virtual hard disks are attached. Increasing this value reduces the number of skipped frames and increases the file size. Frames that have a higher frequency are skipped. Extra memory may be required if display acceleration is used.įrame Rate: Use the slider to set the maximum number of video frames per second (FPS) to record. A rough estimate is (color depth / 8) x vertical pixels x horizontal pixels x number of screens = number of bytes. The minimum value depends on the number of virtual monitors, the screen resolution and the color depth of the host display as well as on the use of 3D acceleration and 2D video acceleration. VirtualBox Manager will show a warning if the amount of video memory is too small to be able to switch the VM into full screen mode. Oracle VM VirtualBox supports symmetrical multiprocessing (SMP) and can present up to 32 virtual CPU cores to each virtual machine. Processor(s): Sets the number of virtual CPU cores the guest OSes can see. If you are looking for a 3D mockup software, consider trying Boxshot which is effectively the new version of Box Shot 3D with many new features. Box Shot 3D was deprecated back in 2013 and we neither sell or renew its licenses, nor providing any support for it.
