System virtual machines take this concept one step further by providing a similar illusion for complete systems.

Regarding virtual machines, assign T (true) or F (false) to the following statements

(  ) A system VM environment is capable of supporting multiple system images simultaneously, each running its own operating system.

(  ) Each operating system controls and manages a set of virtualized hardware resources.

(  ) Each virtual resource may or may not have a corresponding physical resource.

(  ) Real resources of the host platform are shared among the guest system VMs, with a layer of hardware.

(  ) Both virtual machines and native systems have the same capabilities.
