[2017] Nested Virtualization: Hyper-V on KVM by Ladi Prosek

Nested virtualization has been becoming increasingly important. As operating systems have started adopting virtualization-based security features, running a hypervisor as a guest of another hypervisor is no longer just a novelty with little use outside of test environments.

In this talk, Ladi Prosek will briefly describe the architecture of Microsoft Hyper-V as well as virtualization-based features introduced in Microsoft's latest server and desktop operating systems. He will review the work done in KVM so far to support running such systems as KVM/QEMU guests, describe general challenges accommodating non-KVM L1 hypervisors, and present future opportunities in this area.

THANK YOU for the patches to KVM in support of this.

Nested virtualization is the acid test, but is kind of important for many things. (Certainly important for purity.) It's not just a toy or quaint academic thing.
