![]() On this page you will find a table with the download links for this update for Windows 7, 8 and 8.1 (both 32-bit (x86) and 64-bit (圆4)). The "Hyper-V integration components update for Windows virtual machines. Indeed, as you will see later in this tutorial, if you are using Windows 7 or 8 and it's not up to date, you will see that the Microsoft site will be strangely inaccessible. In our case, we used Windows 8.1 as the guest operating system, because this version of Windows is still supported by Microsoft's site even though Windows 8.1 is not yet updated. Important : we recommend that you download the update from your Hyper-V server and then transfer it via an SMB share (for example) to avoid problems accessing the Microsoft site. To download KB3071740 update (corresponding to Hyper-V Integration Services), go to "". Download KB3071740 update (Hyper-V Integration Services) on Windows 8.1 In this registry key, you will find an "IntegrationServicesVersion" data which corresponds to the version of the Hyper-V integration services installed.Ģ. In the registry editor that appears, go to the "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Virtual Machine\Auto" registry key. ![]() To find out the version of Hyper-V Integration Services currently installed in a virtual machine, open the Windows Registry Editor. Find out the version of Hyper-V integration services installed Download and install KB3071740 update (Hyper-V Integration Services) on Windows 7ġ.Download and install KB3071740 update (Hyper-V Integration Services) on Windows 8.Install KB3071740 update (Hyper-V Integration Services) on Windows 8.1.Download KB3071740 update (Hyper-V Integration Services) on Windows 8.1.Find out the version of Hyper-V integration services installed.Source : Integration components available for virtual machines not connected to Windows Update. However, Microsoft provides update KB3071740 for Windows 7, 8 and 8.1 which allows you to manually install these Hyper-V integration services on these older versions of Windows. Indeed, these Hyper-V integration services are now integrated by default in recent versions of Windows (Windows 10 and later) and are then updated automatically via Windows Update. You may also want to assign a DNS server: Get-NetAdapter "vEthernet (VmNat)" | New-NetIPAddress -IPAddress 192.168.100.2 -DefaultGateway of Windows Server 2016, the Hyper-V Integration Services installation disk is no longer available. The gateway IP must point to the NAT adapter from the previous step. Next, assign an IP address to the net adapter: Get-NetAdapter "vEthernet (VmNat)" | New-NetIPAddress -IPAddress 192.168.100.1 -AddressFamily IPv4 -PrefixLength 24Įach nested virtual machine must have an IP address and gateway assigned to it. New-NetNat –Name LocalNAT –InternalIPInterfaceAddressPrefix “192.168.100.0/24” New-VMSwitch -Name VmNAT -SwitchType Internal ![]() The following example creates a new internal switch named VmNAT and creates a NAT object for all IP addresses in the 192.168.100.0/24 subnet. This approach is best suited for cases where MAC address spoofing isn't possible, like in a public cloud environment.įirst, a virtual NAT switch must be created in the host virtual machine (the "middle" VM). ![]() The second option relies on network address translation (NAT). Get-VMNetworkAdapter -VMName | Set-VMNetworkAdapter -MacAddressSpoofing On To enable MAC address spoofing, run the following PowerShell command. In order for network packets to be routed through two virtual switches, MAC address spoofing must be enabled on the first (L1) level of virtual switch. There are two options for networking with nested virtual machines: You can disable nested virtualization for a stopped virtual machine using the following PowerShell command: Set-VMProcessor -VMName -ExposeVirtualizationExtensions $false When using Windows Server 2019 as the first level VM, the number of vCPUs should be 225 or less.
