Parallels Service is a core component of any Parallels hypervisor-based virtualization product. Essentially, when we say "Parallels Service", we mean one of the Parallels virtualization products, such as Parallels Server, Parallels Desktop, or Parallels Workstation. Parallels Service is managed using the prlsrvctl
command-line utility, which is supplied with all Parallels virtualization products and is installed on the host machine during the product installation.
