Summary<\/strong>: Learn how to use Windows PowerShell to change the virtual machine network configuration in Windows Server 2012.<\/span><\/p>\n

Microsoft Scripting Guy, Ed Wilson, is here. If you are a seasoned Hey, Scripting Guy! Blog reader, you know that the most frequent guest blogger is Sean Kearney. If you are new to the blog, I welcome you, and I encourage you to catch up with Sean’s previous blogs<\/a>.<\/p>\n

Sean is a Windows PowerShell MVP and an Honorary Scripting Guy.<\/a> Sean has been selected to present sessions called Integrating with Microsoft System Center 2012 and Windows PowerShell<\/a> at TechEd NA and TechEd Europe this year. In his free time, Sean has written several blog posts about Hyper-V and some other cool stuff, and for a few weeks, Sean will be the designated guest blogger on Fridays. Take it away Sean…<\/p>\n

The other weekend I had a pile of virtual machines on our Windows Server 2012 with Hyper-V box. We had created a new network configuration with a “teamed lan” that we wanted to take advantage of.<\/p>\n

My co-worker and System Center mentor, Brad, looked over, “Sean, can you spend the afternoon and reconfigure the virtual machines to connect to the newly programmed Hyper-V network?”<\/p>\n

I stared at him as if he just gave birth to a bag of corn chips. “Huh? An hour? I’ll bet you that I can do it in less than five minutes!”<\/p>\n

Knowing that I know Windows Powershell, Brad was intrigued, “Prove it!”<\/p>\n

I popped into the environment and ran the following cmdlet to see the names of the switches.<\/p>\n

GET-VMSWITCH<\/p>\n

This produced some useful output in the Windows Powershell console—showing me all of the network switch names and configurations.<\/p>\n

Now my challenge was to know which was the new and which was the old setup. I could look through the GUI console; but with Windows Powershell, I could have it tell me the same thing. <\/p>\n

I pulled down the list of virtual machines with Get-VM<\/strong> and used a new cmdlet from Hyper-V, Get-VMNetworkAdapter<\/strong>. This cmdlet will show me the configuration of the network adapters within a virtual machine.<\/p>\n

GET-VM | GET-VMNetworkAdapter<\/p>\n<\/p>\n

By looking at the list, I could see the old switch configuration that I was using was named “Hyper-V-Lan1.”<\/p>\n

Making the change was so easy that my friend Brad’s eyes popped open just like Jim Carrey in “The Mask.”  I simply invoked another new built-in cmdlet, Connect-VMNetworkAdapter<\/strong>. All I had to do was plug in the new network name I got from Get-VMSwitch<\/strong>.<\/p>\n

GET-VM | GET-VMNetworkAdapter | Connect-VMNetworkAdapter –Switchname ‘New-cool-Hyper-V-Lan’<\/p>\n

I looked up with a big goofy grin on my face, “Done! I’ll see you tomorrow.” <\/p>\n

Brad blinked, “Tomorrow?”<\/p>\n

“You just asked me to spend the afternoon. I did. I just spent it in a more efficient method!”<\/p>\n

The best part is knowing this: I could have just as easily switched the configuration on thousands of machines in a very similar time frame.<\/p>\n

Feel the Power within you.<\/p>\n

Way cool stuff, Sean. Join Sean next week for more Windows PowerShell and Hyper-V stuff. Join me tomorrow for the Weekend Scripter.<\/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
