How to Enable Nested KVM Virtualization

KVM is a virtualization technology that’s integrated into the Linux kernel. A system with KVM enabled can act as a type-1 hypervisor, provided the processor supports it. There are several ways to create a virtual machine using KVM. QEMU can use KVM and libvirt and its Virtual Machine Manager UI provide a convenient interface around it. KVM can be used to create nested virtual machines on compatible hardware. This lets you create VMs inside VMs to accommodate more complex use cases. Consider a virtualized development environment that runs on your host. You might need to run virtual device emulators within that environment, nested two levels deep from the bare metal

Nested Virtualization support finally comes to AMD processors

Nested Virtualization is a popular technology in Windows 10 that was first introduced in 2015. Nested Virtualization technology is used in several ways, some of them include Hyper-V and Android emulation. However, this technology was supported only on Intel processors. Microsoft today announced the much-awaited support for Nested Virtualization in AMD processors. With Windows 10 Insider Build 19636, you can try out Nested Virtualization preview on AMD processors. Since this is a preview release, there are some limitations. Find the details below. Right now, this has been tested on AMD’s first generation Ryzen/Epyc or newer processors Use a Windows guest with an OS version that is greater than or equal
