Re: Enable RDMA on hyperv

Hi,

Please follow the steps for creating Hyper-V virtual switch with RDMA.

Create a Hyper-V Virtual Switch with an RDMA vNIC.

Use the following PowerShell commands to create a Hyper-V Virtual Switch with an RDMA vNIC

# Create a vmSwitch without SET

New-VMSwitch -Name RDMAswitch -NetAdapterName "SLOT 2" 

# Add host vNICs and make them RDMA capable

Add-VMNetworkAdapter -SwitchName RDMAswitch -Name SMB_1
Enable-NetAdapterRDMA "vEthernet (SMB_1)"

# Verify RDMA capabilities

Get-NetAdapterRdma
