| Explanation & Hint:
In the context of virtualization, the terms “host” and “guest” have specific meanings:
- A guest is a virtual machine: True. The guest is the virtual machine (VM) that runs on the physical hardware of the host. It acts like a separate computer within the host machine, with its own operating system and applications.
- The host is the machine that runs the virtual machines: True. The host is the physical computer or server that runs one or more virtual machines. It provides the hardware resources such as CPU, memory, and storage, which are allocated to the guest VMs.
The other statements are not accurate descriptions in the context of virtualization:
- The guest is the machine that runs the virtual machines: This is incorrect. The guest is itself a virtual machine and does not run other virtual machines; that function belongs to the host.
- A host is a virtual machine: This is incorrect. The host is the physical or “real” machine that provides the resources for virtual machines. It is not a virtual entity.
- The terms can be used interchangeably: This is incorrect. The terms “host” and “guest” have distinct meanings in virtualization and cannot be used interchangeably.
Therefore, the correct answers that define the roles in virtualization are that a guest is a virtual machine, and the host is the machine that runs the virtual machines. |
