3.2.2 Modifying the GRUB Configuration File
Depending on the Linux distributions, the system Grand Unified Boot Loader (GRUB)
configuration file may be

to the GRUB file when SR-IOV is enabled.
This section describes how to configure the
iommu.passthrough=1
parameters in the SR-
IOV pass-through mode.
