Some friends here on the Hyper-V team shared a PowerShell 2.0 script for creating a virtual switch:
# Create a Virtual Switch param( [string]$vsName = $(throw "Must specify virtual switch name") ) # Get the Virtual Switch Management Service $vsms = gwmi -namespace root\virtualization Msvm_VirtualSwitchManagementService # Use CreateSwitch method to specify the name, friendly name, learnable addresses, # and authorization scope of the created switch (use "" for the root scope) $result = $vsms.CreateSwitch($vsName,$vsName,2048,"") if($result.ReturnValue -ne 0){ throw "Error: $($result.ReturnValue)" } return ([wmi]$result.CreatedVirtualSwitch)
# Create a Virtual Switch
param( [string]$vsName = $(throw "Must specify virtual switch name") )
# Get the Virtual Switch Management Service $vsms = gwmi -namespace root\virtualization Msvm_VirtualSwitchManagementService
# Use CreateSwitch method to specify the name, friendly name, learnable addresses, # and authorization scope of the created switch (use "" for the root scope) $result = $vsms.CreateSwitch($vsName,$vsName,2048,"") if($result.ReturnValue -ne 0){ throw "Error: $($result.ReturnValue)" } return ([wmi]$result.CreatedVirtualSwitch)
