Didier Van Hoye (VM MVP like me) beat me to blogging about configuring the new options for Live Migration in Windows Server 2012 R2 Hyper-V. He’s doing that a lot lately There Didier shows you how to configure the performance options for Live Migration in the GUI. Here’s how you can do it using PowerShell:
Set-VMHost –VirtualMachineMigrationPerformanceOption <Option>
Where <Option> can be:
- Compression: This is the default option in WS2012 R2 and uses idle CPU capacity (only) to reduce the time to live migrate VMs.
- SMB: Using SMB 3.0 Direct (if RDMA is available) and Multichannel (if multiple NICs are available)
- TCPIP: The legacy non-optimized Live Migration option
Set-VMHost –VirtualMachineMigrationPerformanceOption SMB
And that’s how Ben Armstrong probably scripted his host changes in his TechEd 2013 Live Migration demo (obviously with a lot more logic wrapped around it).

One thought on “Configuring WS2012 R2 Hyper-V Live Migration Performance Options Using PowerShell”
That’s serious scripting… 2 MVPs fighting for the first place for a line of very basic powershell… Come on, one lollypop each and you are all happy 🙂
