Patching of Hyper-V Hosts

Many of you may be using Hyper-V technology as the part of your move towards server virtualization. When you want to patch the Hyper-V hosts which are not equipped with a GUI (Server Core) and not connected to internet, we may want to get the help of WSUS server.

I have employed a manual patching of  Windows Server 2008R2 Hyper-V host using a WSUS Server. As the first step, I have setup , configured the WSUS server as the part of the domain (See the link to see how to configure the Group Policy for this). I have connected my WSUS server to the internet and synced with Microsoft Repository of patches. Now everything is ready to deploy the patches to the Hyper-V Host. Cross check the WSUS console and make sure that the Hyper-V host is visible there (You may want to forcefully  apply the Group Policy)

RDP to the Hyper-V Host and I’m going to work on the PowerShell console as shown below (which comes by default when you RDP the Host):

1Note the 2 option available here, 5)Windows Update Settings 6)Download and Install Updates.

I have opted the option 5 by typing 5 and press enter.

Now the ‘Windows Script Host’ console will open and process the connection to the WSUS Server as shown below:


After a few minutes, we can see the list of available patches at the same window. Again, the program will ask to select the updates needed to install as follows:


Type  the option for you from A,N or S and press Enter.

Finally, we will get the progress as shown below. Some of the updates are not found as successful. Let me try those again, after restarting the host
