KVM/Linux Nested Virtualization Support For ARM

The ARMv8.3 specification is adding support for nested virtualization and already kernel developers have been working to take use of this feature on future ARM CPUs within the Linux kernel.

A set of 55 patches were sent out this morning for supporting KVM nested virtualization under ARMv8.3. Nested virtualization, of course, being the ability to run a virtual machine (VM) inside of another VM or hypervisor on top of hypervisor.

Those interested in the Kernel-based Virtual Machine (KVM) or the potential for ARM nested virtualization can learn more via this patch series. Details on the ARMv8.3 architecture changes via ARM.com.
