VIDEO: Hyper-V v3 in Windows Server 8/2012

This video covers many important features of HyperV version 3 which will be included in Windows Server 2012 as well as Windows 8 desktop, such as:

  • the new VHD format is VHDx and supports upto 16TB
    • multiple VHDx’s can be “pooled” into one virtual disk, up to 64TB in size
  • network card “Teaming” for link aggregation and/or failover is now integrated and supported by Microsoft
    • the NIC’s in the Team do NOT have to be the same type or even the same vendor.  You can mix and match your NIC’s into one Team
  • Multile live Migrations of the VM’s can be done at the same time
    • VHD’s can be live migrated between servers and even between Windows 8 clients
  • When a HyperV “Snapshot” is deleted, the AVHD (delta file) and the VHD (main file) are merged immediately
    • There is no longer a need to shut down the VM to have the merge take place
  • While not covered in the video I think the other major improvement is the ability to connect up to 32 CPU cores to each VM
    • See the table below the video
