ws2008 r2 blog logo With Hyper-V™ live migration, you can move running VMs from one Hyper-V™ physical host to another without any disruption of service or perceived downtime. Live migration is integrated with Windows Server 2008® R2 Hyper-V™ and Microsoft® Hyper-V™ Server 2008 R2. Since Hyper-V™ live migration can move running virtual machines without downtime, it will facilitate greater flexibility and value:

  • Provides better agility: Datacenters with multiple Hyper-V™ physical hosts will be able to move running VMs to the best physical computer for performance, scaling, or optimal consolidation without impacting users.
  • Reduces costs and increase productivity: Datacenters with multiple Hyper-V™ physical hosts will be able to service those systems in a more controlled fashion, scheduling maintenance during regular business hours.

Live migration makes it possible to keep VMs online, even during maintenance, increasing productivity for both users and server administrators. Datacenters will be also able to reduce power consumption by dynamically increasing consolidation ratios and powering off un-used physical hosts during times of lower demand.

  • I wonder how easy it will be to upgrade from Hyper-V Server to Hyper-V Server R2, or if an upgrade is even possible.

    I think we will be using Hyper-V to start out here but i'd like to see us be able to use live migration too.

  • What I would like is an automated tool which will let me take a laptop running Vista, and convert it to Server 2008 while moving my existing Vista installation into a Hyper-V VM for future use.  Is this possible?  Do I lose all the laptop hardware related software such as battery monitors, fan controllers, trackpad drivers, WLAN card drivers, etc etc?

  • Hi Keith

    Thanks for the link to the whitepaper.

    I still find it amusing that live migration is now being pushed extensively by MS with the R2 releases, when originally it was never seen as a requirement in true datacentre environments. I.E. Quick Migration was more than "acceptable".

    Good to see MS coming around finally.

    Cheers

  • Gary,

    You *could* capture your user account with USMT and then use Complete PC Backup on the vista install which turns it into a VHD. Then install Server 2008 and just load the VHD into hyper-v. Then drop your USMT account capture onto 2008 for your account stuff.

    Just a thought.
