Nemu – Modern Hypervisor for the Cloud by Intel

NEMU on the other hand aims to leverage KVM, be narrow focused on exclusively running modern, cloud native workloads, on top of a limited set of hardware architectures and platforms. QEMU also has been the code base on which significant effort and innovation has been invested to create multiple performant I/O models

It also comes with a very large support for legacy features, for platforms and devices and is capable of running on a large number of hardware platforms. QEMU needed emulation support to be build into the code as hardware lacked critical virtualization features.
