Understanding Hypervisors and VMs

What is a hypervisor?

• A hypervisor is a type of operating system.

• A hypervisor is a network protocol for data transfer.

• A hypervisor is a virtualization platform that allows multiple operating systems to run on a single physical machine.

• A hypervisor is a hardware component that manages memory.

What are the two main types of hypervisors?

• Type A and Type B hypervisors

• Type 1 and Type 2 hypervisors

• Virtual and Physical hypervisors

• Open and Closed hypervisors

How does a Type 1 hypervisor differ from a Type 2 hypervisor?

• Type 1 hypervisors can only run on virtual machines.

• Type 1 hypervisors run directly on hardware, while Type 2 hypervisors run on a host operating system.

• Type 1 hypervisors require a host operating system to run.

• Type 2 hypervisors are more efficient than Type 1 hypervisors.

What is the role of a hypervisor in virtualization?

• The hypervisor is responsible for network security in a virtual environment.

• A hypervisor is used to create backup copies of physical machines.

• The role of a hypervisor in virtualization is to manage and allocate hardware resources to multiple virtual machines.

• A hypervisor only runs on dedicated hardware without any virtual machines.

Can you name a popular Type 1 hypervisor?

• Microsoft Hyper-V

• KVM

• VMware ESXi

• Oracle VirtualBox

What is the purpose of a virtual machine monitor (VMM)?

• To store data in a cloud environment.

• The purpose of a virtual machine monitor (VMM) is to manage and run multiple virtual machines on a single physical host.

• To provide a graphical user interface for applications.

• To enhance the performance of a single operating system.

How do hypervisors manage hardware resources?

• Hypervisors directly control physical hardware without abstraction.

• Hypervisors abstract and allocate hardware resources to virtual machines.

• Hypervisors only manage software resources, not hardware.

• Hypervisors eliminate the need for hardware resources altogether.

What are some advantages of using virtual machines?

• Advantages of using virtual machines include resource isolation, flexibility, efficient resource utilization, multi-OS support, and enhanced security.

• Increased hardware costs

• Reduced system performance

• Limited software compatibility

What is the significance of isolation in virtual machines?

• Isolation in virtual machines is significant for security, stability, and resource management.

• Isolation is primarily used for software testing purposes.

• Isolation has no impact on security measures.

• Isolation in virtual machines is only for performance enhancement.

How do hypervisors contribute to cloud computing?

• Hypervisors enable virtualization, maximizing resource utilization and facilitating scalability in cloud computing.

• Hypervisors eliminate the need for network security in cloud environments.

• Hypervisors are primarily used for data storage in cloud computing.

• Hypervisors only manage physical servers without virtualization.
