What is hardware virtualization?
Hardware virtualization is a system that uses one processor to effect as if it were several different computers. It has two main purposes. One is to operate different operating systems on the same hardware. The second is to allow more than one user to use the processor simultaneously. Although there are logistics and financial benefits for hardware virtualization, there are still some practical restrictions.
The name hardware virtualization is used to cover a number of similar technologies that perform the same basic function. Strictly speaking, this should be called hardware virtualization with hardware. This is because the processor itself performs some of the virtualization work. This is unlike techniques that are based only on software. Intel's is known as Intel® VT or IVT. The Advanced Micro Devices is known as AMD-V ™. Other used names, accelerated by accelerated virtualization, hardware virtual machine or native virtualization.
by primary useHardware virtualization is to allow multiple users to access the processor. This means that each user can have a separate monitor, keyboard and mouse and operate their operating system separately. As far as users are concerned, they will effectively operate their own computer. This setting can significantly reduce costs as multiple users can share the same basic hardware.
Someone who approaches a computer through hardware virtualization can be said to operate a virtual desktop. There is a risk that this can cause confusion. This is because the virtual surface is also used to describe functions in some operating systems that allow the user to efficiently expand their desktop on the screen as a visible area on their screen.
There are several significant limitation of hardware. One is that still requires reserved software to perform virtualizace, which can bring additional costs. Another is that, depending on the way the virtualization is performed, it may not be so easy to add additional processing performance later as soon as it is needed.
Perhaps the biggest disadvantage is that no matter how effectively virtualization is performed, the maximum processing power of the chip cannot be exceeded. This means that they must be divided among different users. Whether this is a problem depends on what type of applications is running: the system is more suitable for activities such as web browsing and text processing than activities such as video editing that eats more processor power supply.
