A systems administrator is troubleshooting performance degradation on a server running a Type 1 hypervisor. The physical server's CPU utilization is consistently at 95%, impacting all virtual machines running on it. In this virtualization environment, what is the role of the physical server?
In a virtualization environment, the physical machine on which a hypervisor runs is called the host. The host provides the physical computing resources, such as CPU, memory, and storage, to the virtual machines. The virtual machines that consume these resources are known as guests. A container is a form of operating system-level virtualization and is distinct from a guest VM. The term 'parent' is not the standard industry term for this role; 'host' is the correct term.
