While type 1 is more suitable for large production environments, hosted hypervisors are used for VMs run on personal computers. The most popular type 2 hypervisor software are VirtualBox and VMware. Type 2 (hosted) hypervisors, installed on top of the host operating system.Type 1 bare metal hypervisor, which are installed on the physical server.

They don’t see the host OS nor other VMs running on the same resources. The hypervisor emulates resources so the guest operating systems assume they are using all physical resources. The virtualization layer that abstracts the guest machine and underlying operating system is created with a hypervisor. Doing so reduces the number of physical dedicated servers required. Server virtualization allows you to run multiple operating systems on the same physical resources. It is used by everyone, from enthusiasts to developers. So, the virtual machines running on VMware are extremely portable, allowing system administrators to pause on a one machine, move it to another machine and resume from exactly where it was paused.Virtualization has become the norm for software and OS testing.

Pass-through drivers are provided by the host for USB and Serial/Parallel ports. VMware software provides virtualization of video/network/hard disk adaptors. VMware Player is free software similar to both VMware Workstation and VMware Fusion. VMware Fusion is a similar product intended for Intel Mac users. VMware Workstation allows running multiple x86 or x86-64 operating systems. However, VMware server versions (VMware ESX and VMware ESXi) can run directly on server hardware without requiring an operating system, because they use hypervisor technology (that maps host’s hardware directly to virtual platforms’ resources). Desktop versions of VMware (VMware Workstation, VMware Fusion and VMware Player) can be run on Windows, Linux and Mac OS X. VMware is based in California, USA and was founded in 1998, although now it is owned by EMC Corporation. VMware is a virtualization software developed by VMware, Inc.
