Doc Text:
You can use the weigher `CPUWeigher` to spread (default) or pack workloads on hosts based on their vCPU usage. You can set the nova.conf `[filter_scheduler] cpu_weight_multiplier` configuration option to -1.0 or 1.0. If you set this option to 1.0, instances are spread across hosts. If you set this option to -1.0, instances are packed on a host. If you set the value to 0, the weigher is disabled.
