Problems with Virtual DICE

Printer-friendly versionPrinter-friendly version

If you're having trouble with Virtual DICE, these suggestions may help.

Everything is tiny.

If everything in your Virtual DICE VM looks very small, you can make it larger by switching your VM to Scaled mode then resizing the window with your pointer. This problem can happen on Macs with a Retina display.

To connect a USB peripheral

to Virtual DICE - something other than keyboards and mice, which should just work - you'll need to enable USB. Virtual DICE ships with USB support disabled, because this needs the VirtualBox Extension Pack, which we're not allowed to redistribute. To add USB support, look in the Downloads section of ⇒ virtualbox.org for the VirtualBox version Oracle VM VirtualBox Extension Pack. Once installed, enable USB support for your virtual machine using VirtualBox Settings.

Hardware acceleration

If VirtualBox gives a message like this - VT-x/AMD-V hardware acceleration is not available on your system. Your 64-bit guest will fail to detect a 64-bit CPU and will not be able to boot - then you should enable hardware acceleration (or "virtualization technology") in your computer's BIOS. If this isn't possible, then you should disable hardware acceleration for Virtual DICE. To enable hardware acceleration on a PC, reboot it and enter the BIOS settings, and enable anything labelled Virtualization or VT for Direct I/O or similar. You may find these in the Security section of your computer's BIOS settings. Save your settings and reboot, then try Virtual DICE again. Failing that, disable hardware acceleration in VirtualBox: highlight the Virtual DICE VM but make sure it is not running; click 'Settings' then 'System' then 'Acceleration' and untick ‘Enable VT-x/AMD-V’. Click 'OK' to save that setting then try Virtual DICE again.
