CPU toplogy
For the libvirt driver, you can define the topology of the processors
in the virtual machine using properties. The properties with ``max``
limit the number that can be selected by the user with image properties.

$ nova flavor-key FLAVOR-NAME set hw:cpu_sockets=FLAVOR-SOCKETS
$ nova flavor-key FLAVOR-NAME set hw:cpu_cores=FLAVOR-CORES
$ nova flavor-key FLAVOR-NAME set hw:cpu_threads=FLAVOR-THREADS
$ nova flavor-key FLAVOR-NAME set hw:cpu_max_sockets=FLAVOR-SOCKETS
$ nova flavor-key FLAVOR-NAME set hw:cpu_max_cores=FLAVOR-CORES
$ nova flavor-key FLAVOR-NAME set hw:cpu_max_threads=FLAVOR-THREADS
Where:
- FLAVOR-SOCKETS—(Integer) The number of sockets for the guest VM. By
this is set to the number of vCPUs requested.
- FLAVOR-CORES—(Integer) The number of cores per socket for the guest VM. By
this is set to 1.
- FLAVOR-THREADS—(Integer) The number of threads per core for the guest VM. By
this is set to 1.
Project private flavors
Flavors can also be assigned to particular projects. By default, a
flavor is public and available to all projects. Private flavors are
