To make logical networks available to virtual machines on an external virtual network, you must associate a logical network with the physical network adapter on a host, and configure virtual network settings.
For more information about configuring network settings on Hyper-V hosts, see How to Configure Network Settings on a Hyper-V Host.
The following script takes input for the
VirtualNetName parameters and associates the host with a logical network. The script then creates a virtual network on the host.
# Description: This script associates a virtual machine host with a logical # network and then creates a virtual network for the host. Param ( [parameter(Mandatory=$true)] [String] $VMHostName=$(throw "Please provide the name of a virtual machine host."), [parameter(Mandatory=$true)] [String] $LogNetName=$(throw "Please provide the name of a logical network."), [parameter(Mandatory=$true)] [String] $HostAdapterName=$(throw "Please provide the name of the host adapter."), [parameter(Mandatory=$true)] [String] $VirtualNetName=$(throw "Please provide the virtual network name.") ) # Get the virtual machine host. $VMHost = Get-SCVMHost -ComputerName $VMHostName # Get the logical network. $LogNet = Get-SCLogicalNetwork -Name $LogNetName # Get the network adapter for the host. $HostAdapter = Get-SCVMHostNetworkAdapter -VMHost $VMHost -Name $HostAdapterName # Set the logical network on the host.
