Key Insights

• 🏃 Hypervisors enable running multiple operating systems on limited hardware resources through virtualization.
• 👻 Bare metal hypervisors run directly on system hardware, while hosted hypervisors rely on a host operating system.
• ❓ Different hypervisor vendors offer their own solutions for virtualization, such as VMWare's ESXi and Citrix's XenServer.
• 😶‍🌫️ Hypervisors are essential for resource utilization in cloud computing environments.
• 🚱 The role of the hypervisor is to allocate hardware resources to each operating system and ensure their independence and non-interruption.
• 🎰 Hypervisors are also known as virtual machine monitors (VMM) or virtualization managers (VMM).
• 🪂 Full virtualization and para-virtualization are two approaches used by different hypervisors.

Questions & Answers

Q: What is a hypervisor's role in virtualization?

A hypervisor allows for the virtualization of hardware, enabling running multiple operating systems concurrently on a physical server.

Q: What are the types of hypervisors?

There are two types of hypervisors: bare metal hypervisors that run directly on system hardware, and hosted hypervisors that run on top of a host operating system.

Q: How does a bare metal hypervisor differ from a hosted hypervisor?

Bare metal hypervisors interact directly with hardware, while hosted hypervisors rely on a host operating system for physical resource management.

Q: Are there any popular hypervisor vendors?

Yes, popular hypervisor vendors include VMware, Xen, Hyper-V, KVM, and Oracle.

Summary & Key Takeaways

• Hypervisors enable running multiple operating systems concurrently within virtual servers on a physical server.

• They solve the limitation of having limited hardware resources by virtualizing hardware.

• There are two types of hypervisors: bare metal, which runs directly on system hardware, and hosted, which runs on top of a host operating system.
