![]() ![]() Verify the setup by typing the steps below:.The grub file gets updated automatically if using you’re using a desktop system, however If you’re using a server system, you must enter the update-grub command before rebooting system. Be sure to update grub file, then reboot. ![]() In the nf file, turn on iommu and set it to passthrough mode: intel_iommu=on.Note: iommu enables mapping of virtual memory addresses to physical addresses. Confirm that your Ethernet controller, hypervisor, and guest OS are supported by checking the FAQ for Intel® Ethernet Server Adapters with SR-IOV.Ĭonfirm iommu (or Intel VT-d) is enabled in the BIOS.In this section, we walk through the basic steps required to configure SR-IOV. This article covers the basic steps to create VFs using SR-IOV on Fedora* 4.0.3. SR-IOV is available on a variety of Ethernet controllers across multiple operating systems (both hypervisor and guest OS). Then with network data transferred directly between port and VM, bypassing the hypervisor network stack (and switch layer), traffic on the bus and processor interrupts are significantly reduced. ![]() Depending on the Ethernet controller, you can create 63 or more VFs per physical port. This article describes how to use single root I/O virtualization (SR-IOV), which enables configuration of a single physical network port to provide virtual functions (VFs) to a set of virtual machines (VMs). ![]()
