Give An Example Of Hypervisor

Answer:
Types of Hypervisors
Types of Hypervisors
There are two main types of hypervisor:
Native or “bare metal” hypervisors
Hosted or “embedded” hypervisors
A bare metal hypervisor is installed directly on the hardware of your machine, whereas a hosted hypervisor is installed on your operating system.
Bare metal hypervisors are typically faster and more efficient because they have direct access to the underlying hardware and don’t need to go through the operating system layer. Since they don’t have to compete with other applications or the OS, they can take all the available physical hardware power and allocate it to virtual machines. They also tend to be more secure, because, without an operating system on the host, less attack surface is available for malicious intruders.
However, hosted hypervisors are significantly easier to set up and get running, as you can use the more user-friendly operating system. They’re often used for testing and development purposes, as they can run on the OS to try out new programs or features without affecting the host OS.
VMware and Hyper-V are two key examples of hypervisor, with VMware owned by Dell and Hyper-V created by Microsoft. VMware software is made for cloud computing and virtualization, and it can install a hypervisor on your physical servers to allow multiple virtual machines to run at the same time. Hyper-V does the same thing, but you can also virtualize servers. Hyper-V comes pre-installed with Windows 10. Both are bare metal (native) hypervisors. Oracle VM VirtualBox is a hosted hypervisor.

Best Hypervisor Management Software
It’s a good idea to use third-party hypervisor management software to ensure your hypervisor and virtual machines are working properly. My favorite is SolarWinds Virtualization Manager (VMAN). Why? This tool provides a comprehensive view of your Hyper-V and VMWare environments side-by-side, showing you how your virtualization is connected to applications, servers, and storage.

VMAN also shows you how each of these connections is performing, and gives you information on capacity planning as well as optimization recommendations. Virtualization Manager then allows you to troubleshoot VM issues using the proprietary PerfStack™ feature, which shows you performance issues and how they correlate, helping you discover the root cause more easily.
Another useful feature it offers is built-in management, which means you don’t need to log in to and work through the hypervisor. For security purposes, the tool also includes built-in monitoring and alerts, to help make sure your hypervisor isn’t compromised. The best part? You can try the tool out yourself with a fully functional, free trial for 30 days.
