Introduction to Nesting Virtualization Nested virtualization (nested virtualization, recursive virtualization) is the process of running a hypervisor in a virtualized client, which is then virtualized to run a client. Nested virtualization includes not only the same hypervisor nesting (for example, KVM on KVM, Xen in Xen, VMware on VMware, and so on), but also the different hypervisor nesting (such as VMwa
