Relationship between openstack, KVM, qemu-KVM and libvirt

Openstack, KVM, qemu-KVMAndLibvirtRelationship: KVM Is the lowest level Hypervisor , It is used to simulate CPU , It lacks Network And perimeter I/O So we cannot use it directly. QEMU-KVM Is a complete simulator, It is based on KVMThe above, It provides the complete network and I/O Supported .

coordination between the guest operating system and bare hardware, and some protected instructions must be captured by hypervisor (hypervisor). Full virtualization runs faster than hardware simulations, but is less performance than bare metal. Semi-virtualized (Para virtualization)Para-virtualization is another technology similar to full virtualization, which uses hypervisor to share access to the underlying hardware, but its guest operating system integrates virtualization-related code.

For the configuration of the hypervisor, there are two lines of configuration in the default profile STACKRC of the Devstack source code library: Virt_driver=${virt_driver:-libvirt} LIBVIRT_TYPE=${LIBVIRT_TYPE:-KVM} Therefore, when Devstack installs OpenStack, the default is to set Libvirt as Hypervisor driver, using QEMU/
