HVX: Virtualizing the Cloud
summary
HVX builds a runnable virtual cloud on top of public IaaS by packing a nested hypervisor into each host VM, an image store (S3/cloud-files/backed), and an overlay network using UDP tunnels. It runs unmodified VMDKs (Windows/Linux/Solaris), supports live migration and consolidation, and scales to hundreds of VMs. CPU-bound workloads measure near‑native performance, kernel‑bound workloads show expected penalties comparable to other hypervisors, and the hypervisor uses dynamic binary translation instead of CPU nesting.
