    IOMMU (I / O Memory Management Unit) is any feature supported by motherboard chipsets that typically provides advanced virtual-to-physical memory mapping capabilities, including the ability to map large chunks of memory that are not contiguous. IOMMU can also be enabled in the BIOS or on the motherboard to troubleshoot device driver issues for virtual machines.

    How do I enable Intel IOMMU?

    To deploy SR-IOV to the kernel, change intel_iommu = on in the grub. For best performance, just try adding iommu = pt (pass-through) to your grub file at some point using SR-IOV. In pass-through style, the adapter should not be able to use DMA conversion to conserve memory, which improves performance.

    Generally, restart your computer and take note of the kernel specified to access the installer, or navigate to it in the boot message that appears when you boot the first computer.

    If enabled, a hypervisor or driver system that supports this option, products can use AMD I functionality/ O Virtualization (IOMMU). You can install this to install thisEnabled even if you are not using a hypervisor or business process that uses this option.


    This option is available on servers with AMD processors.

    1. FromFrom the system utilities screen, selectSystem Setup> BIOS / Platform Setup (RBSU)> Virtualization Settings> AMD (R) IOMMU.
