Question

We Have Focused On Isolation Among VMs That Are Running At The Same Time On A Hypervisor. VMs May Shut Down And Stop Executing, And New VMs May Start Up. What Does A Hypervisor Do To Maintain Isolation, Or Prevent Leakage, Between VMs Running At Different

Answer 1

A hypervisor maintains isolation between VMs running at the same time on a hypervisor using memory isolation, resource scheduling, and network isolation.

Step-by-step explanation:

A hypervisor is a software or hardware component that enables the virtualization of physical servers, allowing multiple virtual machines (VMs) to run simultaneously on the same physical server. The primary goal of a hypervisor is to maintain isolation and prevent leakage between VMs running at different times. To achieve this, a hypervisor employs several techniques:

1. Memory Isolation: Each VM is allocated its own dedicated memory space, preventing one VM from accessing or affecting the memory of another VM.
2. Resource Scheduling: The hypervisor schedules and allocates CPU, memory, and other resources among the VMs to ensure fairness and prevent one VM from monopolizing resources.
3. Network Isolation: The hypervisor uses network virtualization techniques, such as VLANs and virtual switches, to isolate network traffic between VMs.

By utilizing these techniques, a hypervisor ensures that VMs running at the same time on a hypervisor are isolated and do not interfere with each other.
