Reasoning for the hypervisors

By navigating through the different OpenStack releases, Nova supports a range of Virtual Machine Monitors (VMMs), also known as hypervisors. Hypervisor software allows access to the physical machine hardware resources and provides different functions to create and manage virtual machines within a compute node. At the time of writing this book, the latest OpenStack releases including the Dalmatian release support Kernel Virtual Machine (KVM), LXC, QEMU, VMware vSphere (5.1.0 and later versions), zVM, Ironic (native OpenStack bare metal), Hyper-V, and Virtuozzo (7.0.0 and later versions). The different features and virtual machine management capabilities differ from one hypervisor to another. A full list of supported features per hypervisor can be found in the official hypervisor support matrix, which is available at https://docs.openstack.org/nova/latest/user/support-matrix.html.
