What are the three methods of gpu virtualization?

Three methods of GPU virtualization: 1. Hardware virtualization: Use hardware virtualization technology, such as Intel VT-d or AMD-Vi, to create a direct communication channel between the physical GPU and the virtual machine ; 2. Software virtualization: Use software virtualization technology, such as VMware or Citrix, to simulate the physical GPU in the host operating system; 3. GPU pass-through: This method directly assigns the physical GPU to the virtual machine, and the virtual machine can directly access it Physical GPU resources.

There are three methods of GPU virtualization, including hardware virtualization, software virtualization and GPU pass-through.

1. Hardware virtualization: Use hardware virtualization technology, such as Intel VT-d or AMD-Vi, to create a direct communication channel between the physical GPU and the virtual machine.

2. Software virtualization: Use software virtualization technology, such as VMware or Citrix, to simulate a physical GPU in the host operating system. This method emulates the GPU and allows the virtual machine to access the GPU device.

3. GPU pass-through: This method directly allocates the physical GPU to the virtual machine, and the virtual machine can directly access the resources of the physical GPU. This method has the least impact on the performance of the virtual machine, but it needs to ensure compatibility between the host operating system and the virtual machine operating system.
