Change Guest VM IP from Hyper-V Host

Since Windows Server 2012, Microsoft introduces the ability to change or inject IP configuration of Guest VM from its HyperV host. This feature is using Msvm_GuestNetworkAdapterConfiguration class.

Below is the PowerShell Script from itprotoday to change/inject the Guest VM IP. Replace the name of the VM as needed and the IP configuration.

 $vmName = "win81g2"
 $Msvm_VirtualSystemManagementService = Get-WmiObject -Namespace root\virtualization\v2 -Class Msvm_VirtualSystemManagementService
 $Msvm_ComputerSystem = Get-WmiObject -Namespace root\virtualization\v2 -Class Msvm_ComputerSystem -Filter "ElementName='$vmName'"
 $Msvm_VirtualSystemSettingData = ($Msvm_ComputerSystem.GetRelated("Msvm_VirtualSystemSettingData","Msvm_SettingsDefineState", $null, $null, "SettingData", "ManagedElement", $false, $null) | % {$_})
 $Msvm_SyntheticEthernetPortSettingData = $Msvm_VirtualSystemSettingData.GetRelated("Msvm_SyntheticEthernetPortSettingData")
 $Msvm_GuestNetworkAdapterConfiguration = ($Msvm_SyntheticEthernetPortSettingData.GetRelated("Msvm_GuestNetworkAdapterConfiguration", "Msvm_SettingDataComponent",$null, $null, "PartComponent", "GroupComponent", $false, $null) | % {$_})
 $Msvm_GuestNetworkAdapterConfiguration.DHCPEnabled = $false
 $Msvm_GuestNetworkAdapterConfiguration.IPAddresses = @("192.168.1.207")
 $Msvm_GuestNetworkAdapterConfiguration.Subnets = @("255.255.255.0")
 $Msvm_GuestNetworkAdapterConfiguration.DefaultGateways = @("192.168.1.1")
 $Msvm_GuestNetworkAdapterConfiguration.DNSServers = @("192.168.1.10", "192.168.1.11")
 $Msvm_VirtualSystemManagementService.SetGuestNetworkAdapterConfiguration($Msvm_ComputerSystem.Path, $Msvm_GuestNetworkAdapterConfiguration.GetText(1))

If you want to set the IP configuration to DHCP, you can change the DHCPEnabled to $true and omit the IP address, Subnets, and Default Gateways.

If the operation is performed asynchronously, this method will return 4096.
