VM communication – this feature controls how VMs connect to other VMs or hosts in the network.VM isolation – all VMs are entirely isolated each VM has its own emulated hardware and OS.VMs management – start, stop, and control VM lifecycle.Resources distribution – distribute CPU, memory, and network resources between other VMs.Partitioning – split the host computer’s underlying hardware between different virtual machines.Another critical feature of a hypervisor is that it isolates virtual machines from each other and the host computer. The hypervisor’s role is to provision, spin up, and retire the virtual machines as needed. In comparison, VirtualBox and Parallels Desktop occupied the Desktop market. For example, ESXi, Hyper-V, KVM, and Xen are used for server virtualization. There are many different hypervisors available on the market:Įach of the products has its purpose. And it is impossible to cover any Linux-related topic without mentioning this one. The primary use case of this technology is the virtualization of servers and applications. Each of them, in this case, acts as a dedicated server with smaller compute resources.
