Which resource must a hypervisor provide to virtual machines?

A hypervisor is a software layer that creates and runs virtual machines (VMs). To function, every VM requires fundamental computing resources, and a processor (CPU) is one of the most critical. The hypervisor allocates virtual CPUs to VMs, which are then mapped to the physical CPU cores of the host server. Without a processor, a VM cannot execute instructions or perform any computational tasks. Bandwidth is a network resource, not a core computing resource directly provided by the hypervisor for a VM's internal operation, though the hypervisor manages virtual network interfaces. An IP address is a network configuration detail assigned to a VM's network interface, not a resource the hypervisor provides in the same way it provides CPU. Secure access relates to management and isolation, which the hypervisor facilitates, but it's not a fundamental computing resource like a processor.
