Virtualization is nothing but abstracting operating system, application, storage or network away from the true underlying hardware or software. It creates the illusion of physical hardware to achieve the goal of operating system isolation.

In last decade, data centers were occupied by a large number of physical servers, network switches, storage devices. It consumed a lot of power and manpower to maintain the data centers. So I have just listed down only the server virtualization types. Virtual machine simulates hardware to allow an unmodified guest OS to be run in isolation.

There is two type of Full virtualizations in the enterprise market. It completely relies on binary translation to open hardware virtualization 12 and virtualize the execution of sensitive, non-virtualizable instructions sets. It emulates the hardware using the software instruction sets. Due to binary translation, it often criticized for performance issue.

Here is the list of software which will fall under software assisted BT. Hardware-assisted full virtualization eliminates the binary translation and it directly interrupts with hardware using the virtualization technology which has been integrated on X86 processors since Intel VT-x and AMD-V.

Here is virtualizwtion list of enterprise software which supports hardware-assisted — Full virtualization which falls under hypervisor type 1 Bare metal. Paravirtualization works differently from the full virtualization. Open hardware virtualization 12 hypervisor is installed on a physical server host and a guest OS is installed into the environment.

In this virtualization method, guest virgualization codes will be modified with sensitive information to communicate with the host. Guest Operating systems require extensions to make API calls to the hypervisor. In full virtuaalization, guests will issue a hardware calls but in paravirtualization, guests will directly communicate with the host hypervisor using the drivers.

Here is the lisf of products which supports paravirtualization. The below diagram might help you to understand how Xen open hardware virtualization 12 both full virtualization and paravirtualization. But it does for Linux guest by modifying the kernel. In Hardware assisted full virtualization, Guest operating systems are unmodified and it involves many VM traps and thus high CPU overheads which limit the scalability.

Paravirtualization is a complex method where guest kernel needs to be modified to inject the API. By considering these issues, engineers have come with hybrid open hardware virtualization 12. The following products support hybrid virtualization.

The following diagram will help you to understand how VMware supports both full virtualization and hybrid virtualization. Operating system-level virtualization is widely used. Host Operating virtuailzation kernel allows multiple user spaces aka instance. In OS-level virtualization, unlike other virtualization technologies, there will be very little or no overhead since its uses the host operating system kernel for execution.

Hardwae Solaris open hardware virtualization 12 is one of the famous containers in the enterprise market. Here is the list of other containers. Each virtualization technologies have their own advantages and disadvantages. The choice of virtualization heavily depends on use and cost. There are a lot of technologies are evolving and enterprise products support hxrdware virtualization types open hardware virtualization 12 improve the performance and reduce the resource overhead.

I know its bit hard to understand and classify the virtualization technologies. But I have tried my level best to put it together. Awesome article and Thanks so much, It was completely clear and well-explained Virtualization even maybe better than some references.

After open hardware virtualization 12 3 articles,I found it very useful and without ambiguity, Again special thanks the author. Hi, thanks, It helps me very much to understand virtualization type.

Binary translation is one open hardware virtualization 12 approach to implementing full virtualization that does not require hardware virtualization virtualizatioj. So in short, hypervisor is running in ring 1 of host OS and guest OS running in any of the higher rings than ring 1 say ring 2any ring stated above that see carefully; as you can see that there is ring 0 then ring 1 then ring 0, see the open hardware virtualization 12 belongs to the guest OS.
