FREMONT, CA: Microsoft announces the availability of Nested Virtualization capability in its latest build 10565 of Windows 10 to Windows Insiders on the Fast ring. The Redmond software giant is delivering its promises of running a Hyper-V Containers in Hyper-V virtual machines.

The first public preview of nested virtualization feature will enable users to run a Hyper-V in a virtual machine. The release is at an ‘early preview’ stage and both hypervisors need to be the latest versions of Hyper-V with Windows Server 2012R2 or the latest build 10565. Enabling nested virtualization requires a minimum of 4GB RAM and is currently supported only on Intel Virtual Technology hardware. The company cautions users of known issues that are encountered in the build.

Nested Virtualization

Nested Virtualization is the ability to run a hypervisor inside of a virtual machine. Hyper-V relies on hardware virtualization support to run virtual machines. Hypervisors typically hide this capability from guest virtual machines preventing them from loading Hyper-V server role among other hypervisors. Nested virtualization unlocks those hardware virtualization support components to guest virtual machine.

With the latest build Microsoft is showcasing nested virtualization capability for its Hyper-V containers solution which will potentially be an emerging feature of Windows Server 2016, reports Kurt Mackie for Virtualization Review.
