7. Hyper-V > Managing Virtual Machines and Virtual Disks

Managing Virtual Machines and Virtual Disks

The following sections give step-by-step walk-throughs on some of the most important features in Hyper-V R3.

Live-Migrating Virtual Machines

Hyper-V R3 marks a big improvement with live migration—that is, moving VMs from one physical host to another without downtime. That improvement is the ability to migrate VMs without shared storage or having both hosts in a cluster, either of which is required for live migration in Windows Server 2008 R2.

Simpler live migration is a must-have feature in virtualized environments. Being able to quickly transfer over a VM from one physical host to another is critical to quickly getting up and running in the event of a disaster. If one host goes down, you can move a VM to another host.
