| + | |||
| + | builder = "hvm" | ||

| + | </file> | ||
| + | |||
| + | ===== Sound and USB ===== | ||
| + | * Since the physical video output of the passed video card is used there will be no SDL/VNC screen this means that a sound card must also be passed for the vm to have sound | ||
| + | * For that same reason as above you will want to pass one USB controller for input | ||
