Virtualization
Virtualization is a software layer between Hardware and OperatingSystem.
Virtualization allows multiple Operating System (OS)instances to run concurrently on a single computer.
Hypervisor is divided into two classifications:tt
Type1 (ornative,baremetal)hypervisorsrundirectlyonthehost'shardwaretocontrolthehardwareandtomanageguestOS’s.AguestOSthusrunsonanotherlevel abovethehypervisor.
Examples: Oracle VM Server For SPARC,the Citrix XenServer,KVM,VMware ESX/ESXi,and Microsoft Hyper-V Hypervisor.
Type2:(orhosted)hypervisorsrunwithinaconventionalOSenvironment.Withthehypervisorlayerasadistinctsecondsoftwarelevel,guestOSsrunatthethirdlevelabove thehardware.
Examples: VMware Player,VMware Workstation and VirtualBox.
In other words,Type 1 hypervisor runs directly on the hardware; Type 2 hypervisor runsonanotherOS,such as FreeBSD,Linux or Windows.
In real time Baremetal installation will be done .
Virtualization technology Supports x86 platform only.
