Windows Server 2012: Doing multiple configuration changes on Hyper-V VMs via PowerShell

Windows Server 8

Over the weekend I was Setting up my lab for the RTM of System Center 2012. I created some Windows Server 2008 R2 Virtual Machines on my Windows Server 2012 beta Hyper-V server. After I had created all VMs and installed them, I realized I forgot to configure the limit for Dynamic Memory for the Hyper-V Virtual Machines.

Now here the new PowerShell module for Hyper-V which comes with Windows Server 2012 helped me save some time.

Hyper-V PowerShell


First I check the Dynamic Memory Maximum value for all my System Center 2012 Virtual Machines.

Get-VM -Name SC2012* | ft Name, MemoryMaximum

After that I changed the value from all my System Center 2012 Virtual Machines to 8GB

Get-VM -Name SC2012* | Set-VM -MemoryMaximumBytes 8589934592

btw. if you don’t know that 8GB are 8589934592 Bytes PowerShell can help you, check this out:

Get-VM -Name SC2012* | Set-VM -MemoryMaximumBytes 8GB

Ben Armstrong, Virtualization Program Manager, did also a blog post on performing bulk configuration changes in Hyper-V via Windows PowerShell on his blog.
