Not all environments always have virtualization capabilities supported by the CPU, for example, test environments running the Nova Compute nodes on virtual machines. In such cases, we can configure Nova to use a QEMU virtualization hypervisor emulation. This significantly reduces the performance of virtual machine instances running with the QEMU hypervisor emulation, but allows you to run virtual machine instances without virtualization support by the CPU.
