Configuring Share-Nothing Live Migration in Windows Server 2012 R2 Hyper-V

Moving a running virtual machine from one host to another with no downtime to running applications is called Live Migration that works with Standalone servers or Failover Cluster server. Live migration without shared storage (also known as “Shared Nothing” live migration) is new in Windows Server 2012, and it’s continue in Windows Server 2012 R2 with some add Advanced features in Performance options like TCP/IP, Compression and SMB. Compression features is enabled by default and over 2x improvement in live migration time with the existing hardware. It enables you to migrate your virtual machines and their associated storage between servers running Hyper-V within the same domain. This kind of live migration uses only an Ethernet connection. This live migration solution does not provide high availability – there is no shared storage. If you are managing a Hyper-V host remotely and you want to move a virtual machine, you must first allow Kerberos protocol delegation for the computer account of the Hyper-V host.

Here, I will show you how to configure Live Migration without shared storage.

  • The source and destination Hyper-V Hosts belong to the same Active Directory Domain or to domains that trust each other.
  • On the Hyper-V Host, log in as a member of the Domain Administrators group to perform live migration.
  • Keep Hosts Consistent in all Hyper-V Hosts (optional) as shown in figure.Hosts Consistent in Hyper-V

Task 3: Performing Live Migration Move a Virtual Machine:

1. On KTM-HOST1, In Hyper-V Manager, right-click KTM-WEB-2K12, and then click Move.


2. In the Move “KTM-WEB-2K12” Wizard, On Before You Begin page, click Next.


3. On the Choose Move Type page, select Move the virtual machine and then click Next.
