Summary<\/b>: Microsoft Scripting Guy, Ed Wilson, talks about the problem of updating virtual machines.<\/span><\/p>\n

Microsoft Scripting Guy, Ed Wilson, is here. This afternoon I am sipping a nice cup of red berry tea. I also have a bowl of grapes and a bit of brie. The berry tea, grapes, and brie are a nice combination, and light enough that it makes a nice afternoon snack.<\/p>\n

One of the great things I love about Windows 8.1 is that it has real Hyper-V built-in to it, and it has Windows PowerShell cmdlet support for managing those virtual machines. The performance is really good, and it means that I can create a virtual machine on my laptop that replicates virtual machines in production. It makes a great test environment.<\/p>\n

My test network is completely isolated and I use the internal switch so the virtual machines can talk to each other. This is perfect for most occasions. The problem comes when I want to update those virtual machines.<\/p>\n

Here is an overview of the scenario…<\/p>\n

I need to first change from the internal switch type to a network adapter that uses the Ethernet connection. Luckily, I can do this while the virtual machine runs. I open Hyper-V Manager, right-click the name of the virtual machine, and choose Settings<\/b> from the action menu. I then look for Network adapter<\/b> under the Hardware<\/b> section. I change the network adapter (virtual switch) to use the Ethernet network adapter from my host machine. This is shown here:<\/p>\n

\"Image<\/a><\/p>\n

Now I need to go into the virtual machine and modify the network adapter settings. This means that I right-click the network adapter icon on the tool bar, I choose Open Network and Sharing Center<\/b>, select Change adapter settings<\/b>, find my network adapter in Network Connections<\/b>, right-click the adapter, choose Properties<\/b>, scroll down until I find Internet Protocol Version 4 (TCP\/IPv4), and again select Properties<\/b>.<\/p>\n

Now I change from a static IP address to a dynamic-assigned IP address and DNS. This is shown here:<\/p>\n

\"Image<\/a><\/p>\n

Then I click OK<\/b>, click Close, X, X…wait for things to freeze a couple times, open Windows PowerShell, type IPConfig<\/b> and look to see if I have a new IP address. If I do, great! If not, I need to investigate ipconfig\/renew<\/b>.<\/p>\n

If that doesn’t work, I need to disable the network adapter, re-enable it, and type ipconfig\/renew<\/b> again. If that doesn’t work, I reboot the virtual machine. Usually that will work. Today, it looks like everything is going well, and that it works. I open Internet Explorer to verify that I have Internet connectivity. This also works.<\/p>\n

So I open Control Panel<\/b>, System and Security<\/b>, Windows Update<\/b>, and Check for Updates<\/b>, and again wait a while…<\/p>\n

As shown here, there are a few updates that I need to install:<\/p>\n

\"Image<\/a><\/p>\n

And now I wait for a while again. Hmmm…<\/p>\n

While I am waiting, I think I will go make a cup of tea. Back in a while…<\/p>\n

Well, that all took a while, and now I need to reboot the virtual machine. Then I have to reverse the process: change back to the virtual switch, go back into the network adapter, and configure a static IP address.<\/p>\n

So there is a description of the problem I face. When I have multiple virtual machines that I need to update, it takes a while. So, this becomes a great area for automation—and that is just what Sean will do tomorrow.<\/p>\n

Join me tomorrow when I have a guest article by Microsoft PowerShell MVP and Honorary Scripting Guy, Sean Kearney. He will talk about performing an offline update.<\/p>\n

I invite you to follow me on Twitter<\/a> and Facebook<\/a>. If you have any questions, send email to me at scripter@microsoft.com<\/a>, or post your questions on the Official Scripting Guys Forum<\/a>. See you tomorrow. Until then, peace.<\/p>\n
