Virtualization Architecture
There are two virtualization architecture provided by VMware.
A) Hosted Virtualization Architecture
B) Native Virtualization Architecture
Both Architecture are completely transportable between each other.
Hosted Virtualization Architecture : VMware's GSX Server, Workstation, Vmware Player, ACE use this architecture. The virtualization layer install on the top of the host Operating System and run like an application on the OS. It completely relies on the host OS's device support and the physical resource management. The virtualization layer doesnt have comtrol over the allocation of the physical hardware resources.
Native Virtualization Architecture: It provides bare-metal virtualization. it installs directly onto the harware. ESX server is based on this virtualization architecture. ESX server installs directly onto the hardware. it controls the share of the hardware resources allocated to the virtual machine. Second part of VMware's native virtualization is the Service console. This is a stripped-down virtual machine instance that controls starting, stopping, and administrating the other virtual machine on the physical system.It can also be used for agents and helper applications that need visibility to all of the virtual machines on the physical system.
