%description
Cloud Hypervisor is an open source Virtual Machine Monitor (VMM) that runs on top of KVM. The project focuses on exclusively running modern, cloud workloads, on top of a limited set of hardware architectures and platforms. Cloud workloads refers to those that are usually run by customers inside a cloud provider. For our purposes this means modern Linux* distributions with most I/O handled by paravirtualised devices (i.e. virtio), no requirement for legacy devices and recent CPUs and KVM.
