Implementing nested Hyper-V
Nested Hyper-V is a cool feature of Windows 2019 and Windows 10 (Anniversary Update and later). Nested Hyper-V enables a Hyper-V VM to host VMs that also have virtualization enabled. You could, for example, take a physical host (say, HV1) and on that host run a VM (PSDirect). With nested Hyper-V, you could install Hyper-V in the PSDirect VM to enable that VM to host further VMs.
Nested VMs have a number of uses. First, nested VMs hosted in one VM are provided hardware isolation from nested VMs run in other VMs. This provides a further level of security for virtual machines. Nested Hyper-V is also useful for testing and education/training. In a training course, you could give a student one VM (running in a large blade server) and enable the student to create additional VMs as part of the course. You could, for example, run the recipes in this chapter using nested VMs.
Enabling nested Hyper-V is very simple. First, you must update the virtual CPU in the VM you want...
