PCI passthrough, however, has many other applications: for example, it lets you use a Digium phone card on an Asterisk VOIP server contained within a VM, if you have a PCI RAID controller not supported by a propietary VM hypervisor like VMware ESX you can pass it through to your VM, or it can let you use a high-end audio card for professional audio production that only has drivers for Windows and Mac OS X. PCI passthrough is also often known as IOMMU, although this is a bit of a misnomer, since the IOMMU is the hardware technology that provides this feature but also provides other features such as some protection from DMA attacks or ability to address 64-bit memory spaces with 32-bit addresses.Īs you can imagine, the most common application for PCI passthrough at least on the chansphere is vidya, since PCI passthrough allows a VM direct access to your graphics card with the end result of being able to play games with nearly the same performance as if you were running your game directly on your computer.

The device acts as if it were directly driven by the VM, and the VM detects the PCI device as if it were physically connected.

PCI passthrough is a technology that allows you to directly present an internal PCI device to a virtual machine.
