It has been revealed in a recent leaked build, that the operating system Microsoft currently code names Windows 8, contains Hyper-V 3.0 technology and a new virtual hard drive format called VHDX.

It has been assumed by several sites that the features have been a part of Windows 8 for quite some time, however due to the lack of 64-bit builds and more focus being placed on mainstream consumer features, they were yet to be picked up by enthusiasts.

Both features have been uncovered by enthusiasts digging around the leaked build. Robert McLaws has detailed the support in a blog post on Monday. Windows 8 build 7989 includes the following Hyper-V 3.0 features:

  • Storage
    • Virtual Fibre Channel Adapter
    • Storage Resource Pools
    • New .VHDX virtual hard drive format (Up to 16TB + power failure resiliency)
  • Memory/Processor Enhancements
    • Support for more than 4 cores! (My machine has 12 cores)
    • NUMA – Memory per Node, Cores per Node, Nodes per Processor Socket
  • Networking Enhancements
    • Hardware Acceleration (Virtual Machine Queue & IPsec Offload)
    • Bandwidth Management
    • DHCP Guard
    • Router Guard
    • Monitor Port
    • Virtual Switch Extensions
    • Network Resource Pools

 

Windows 8: Hyper-V 3.0 and new VHDX virtual hard drive format discovered 1

 

This is a huge step forward for Windows 8. I believe it will have a huge impact on a wide array of usage scenarios, the least of which is the potential for self-contained App-V / Windows XP Mode support. Not to mention better Windows Phone 7/7.5/8 Emulator support. it will be interesting to see how this impacts the virtual desktop software market. The potential of the new features could well benefit developers and the tech-savvy alike, making it easier for people to have access to all the features that some come to expect from virtualisation software.
