The Hyper-V Import/Export feature allows virtual machines to be migrated from one Hyper-V server to anotherregardless of whether the Hyper-V hosts are part of a Failover Cluster. In this chapter of [[Hyper-V Essentials]] we will cover the concept of virtual machine migration using this approach. For details on how to perform a live migration between nodes in detailFailover Cluster using the features of Hyper-V 2008 R2, refer to the chapter entitled [[An Overview of Hyper-V Live Migration]].
== The Capabilities and Restrictions of Virtual Machine Migration ==
Before attempting to migrate a Hyper-V virtual machine between servers using import/export, there are some rules and restrictions that are useful to know about it advance.
Firstly, a virtual machine can only be exported if it is shut down or saved. A running or paused virtual machine cannot be migrated. Some readers may be familiar with the live migration capabilities of virtual solutions such as Xen and VMware VMotion which allow a running virtual machine to be moved from one server to another without any perceptible interruption of service. Whilst Microsoft are working on such a feature for Hyper-V, the current version supports only the static migration of a powered off virtual machine.
The first step in exporting a Hyper-V virtual is to launch the Hyper-V Manager console (''Start->Administration Tools->Hyper-V Manager''). From within Hyper-V Manager, ensure that the virtual machine to be exported is either powered off or in a saved state by selecting it from the list of virtual machines and selecting the appropriate action from the ''Actions'' panel.
Once the virtual machine is power powered off or saved, click on the ''Export..'' action link to display the ''Export Virtual Machine'' dialog as illustrated in the following figure:
