DESCRIPTION


The Enable-NetAdapterSriov cmdlet enables Single-Root I/O Virtualization (SR-IOV) on the network adapter. SR-IOV enables network traffic to by-pass the software switch layer
of the Hyper-V virtualization stack. As a result, the I/O overhead in the software emulation layer is diminished and can achieve network performance that is nearly the same
performance as in non-virtualized environments. SR-IOV can only be used if enabled on the network adapter.
