  # CPU topology
  # The product of the values of all parameters must equal the maximum number
  # of vcpu:
  #   sockets * dies * cores * threads = max_vcpus
  # dies is optional and equals 1 by default.
  #
  # If you need a complex topology, you will have to sacrifice the ability to
  # hotplug vCPUS. You will need to set 'max_vcpus' to equal 'vcpus'. To apply
  # the changes you will need to perform a power reset or manually shutdown
  # and start instance (not reboot or reset).
  #
  # By default, the number of sockets will be set to the number of vCPUS. You
  # may want to use a single socket without sacrificing the vCPUS hotplug, so
  # you can set the following values:
  #
  #   topology:
  #     sockets: 1
  #     cores: 4
  #     threads: 1
  #
  # Note that the value of 'cores' must be equal to 'max_vcpus'.
  topology:
    sockets: 1
    dies: 1
