Notes on Taking KVM-on-KVM Nested Virtualization for a Spin - Kashyap Chamarthy, Red Hat

Sign up or log in to save this to your schedule and see who's attending!

Nested Virtualzation involves three levels -- The physical host (L0), running a guest hypervisor (L1), and its associated 'nested' guest (L2). This is useful in several ways: a cloud user can get a guest hypervisor and can manage a variety of guests for development/test without the intervention of the cloud provider; enable live migration of hypervisors; ability to have an entire virtualization setup - a hypervisor and all its guests in a single virtual machine. Support for nVMX (Intel based Nested Virtualization) was first introduced around two years ago in KVM. Since then, there have been improvements in the Kernel, and also in the hardware space. This session discusses observations from recent testing of some workloads with upstream KVM with newest Intel hardware in a Linux-on-Linux environment. Finally, a glimpse of upcoming improvements in this space.
