Paravirtualization**: The hypervisor provides efficient hypercalls, and the guest OS uses drivers and kernel modifications to call these hypercalls. Virtualized in Hardware**: Hardware support for virtualization, and near bare-metal speeds. But not all workloads: some are network bound (proxies) and storage bound (databases). ## 5.
