The hypervisor can be explained as a Virtual Machine Monitor (VMM) is computer software, firmware or hardware that creates and runs virtual machines, whereas system on which a hypervisor runs more than one virtual machine can be known as a host machine, and each virtual machine is called a guest machine. The best example of Hypervisor can be as follow: Oracle Virtual Box, Parallels and VMware Workstation, VMware Fusion, Oracle VM for x86 and Solaris Zones.
The Hypervisor can be classified into two types please find below:
As we know that VMs can run on the same physical hardware, still if we see then they are logically separated from each other, which clears states that if one VM experiences an error, crash or any malware then it can extend to other VMs on the same machine or even other machines. Further, VMs are Independent they can be migrated between local or remote virtualized servers.
While Choosing the right hypervisor the best way is to determine which hypervisor meets your needs is to compare their performance metrics. Not metrics alone but in addition to the capabilities of the hypervisor, one must also verify the guest operating systems that each hypervisor supports. For example, if you run a homogeneous network based on Windows or Linux, then support for a smaller number of guest operating systems might fit your needs.
