In Xen, the use of virtual CPUs (vCPUs) in a DomainU is critical for performance. How can you define the number of vCPUs allocated to a DomainU in its configuration file?
1. By modifying the hypervisor settings only.
2. By specifying vCPUs in the xl command during creation.
3. By using the cpu parameter in the .cfg file.
