What is KVM passthrough?
From Gentoo Wiki. GPU passthrough is a technology that allows the Linux kernel to directly present an internal PCI GPU to a virtual machine. 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.
How can I tell if Vt D is enabled Linux?
If VT-d is enabled, Linux will configure DMA Remapping at boot time. The easiest way to find this is to look in dmesg for DMAR entries. If you don’t see errors, then VT-d is enabled. Either way, you’re looking for that last line, DMAR-IR: Enabled IRQ remapping in mode .
What is VirtIO driver?
VirtIO Drivers are paravirtualized drivers for kvm/Linux (see http://www.linux-kvm.org/page/Virtio). In short, they enable direct (paravirtualized) access to devices and peripherals for virtual machines using them, instead of slower, emulated, ones.

Intel VT-d makes direct access to a PCI device possible for guest systems with the help of the Input/Output Memory Management Unit (IOMMU) provided. This allows a LAN card to be dedicated to a guest system, which makes attainment of increased network performance beyond that of an emulated LAN card possible.
