virtual CPUs (vCPUs).

Possible values:

* A comma-separated list of physical CPU numbers that virtual CPUs can be
  allocated to by default. Each element should be either a single CPU number,
  a range of CPU numbers, or a caret followed by a CPU number to be
  excluded from a previous range. For example:

* nova-compute
