> VFIO Stupid question (since there is no Wikipedia lemma for that term): is that the same as IOMMU? http://enwp.org/IOMMU_hardware_list http://enwp.org/IOMMU_

  VFIO relies on IOMMU capability to allow devices to be passed through to guests, but it isn't just IOMMU. The common modern arrangement for VFIO is to use KVM+qemu with libvirt. Of practical concern is finding out which devices are in which IOMMU groups, because devices within the same group can't be split. For instance, if you had an ethernet controller with two ports, they'd both likely be in the same group, so you couldn't give one to the host and one to a VM.
