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
