Microsoft Hypervisor (Hyper-V) is a virtualization technology developed by Microsoft which specifically serves as hardware virtualization, allowing users to run multiple operating systems virtually on Windows platform.

Now, Microsoft is looking to make Linux run as a root partition on its Hyper-V technology, with the company's engineer Wei Liu pushing out a series of patches to Linux’s Hyper-V code. While the RFC (request for comment) patches are aimed at making Linux run as a root partition (like Xen’s Dom0) on Hyper-V.

Hyper-V not only lets you run multiple virtual operating systems on the Windows platform, but also, it allows users to create virtual hard drives and network switches.

How Linux root partition support for Microsoft Hypervisor will work?



Microsoft is looking to create a complete virtualization stack with Linux and Microsoft Hypervisor, which will be a subsequent patch series to provide a device node (/dev/mshv) such that userspace programs can create and run virtual machines.



It also involves the porting of Virtual Machine Monitor (VMM) Cloud Hypervisor, and been able to boot a Linux guest with Virtio devices, which capabilities were added since late July. And as an RFC series, this implements only the absolutely necessary components that are required to get things running.

With a large portion of the series consisting of patches that augment hyperv-tlfs.h, which should be rather uncontroversial and can be applied right away.

The architecture documentation of Hyper-V implies that the root partition has direct access to physical I/O devices, so the virtualization stack in the root partition can provide a memory manager for virtualized I/O devices and management APIs. And the root partition for Microsoft Hypervisor is inspired by type-1 hypervisor (Xen), and Domain 0 (Dom0) of open source, which toolstack and drivers are for hardware that control virtual machines.
