Embodiment 1

[0048] Such as figure 1 As shown, the technical solution of the present invention provides a direct method for a GPU device under Linux KVM, comprising the following steps:

[0049] S1: Install RHEL-KVM and set the Ethernet mode;

[0050] In this step, install RHEL7 and select the Ethernet mode as ON.

[0051] Use Base Environment = "Virtualization Host" (select related software packages) select BaseEnvironment as "Server+UI" and select all software packages under it.

[0052] S2: Add virtualization commands to the boot manager GRUB;

[0053] It should be noted that after completing the installation, add the "nouveau.modeset=0intel_iommu=on" line, as follows:

[0054] #vi / etc / default / grub

[0055] GRUB_CMDLINE_LINUX="rd.lvm.lv=rhel_dhcp-10-24-169-21 / swap

[0056] vconsole.font=latarcyrheb-sun16-rd.lvm.lv=rhel_dhcp-10-24-169-21 / root

[0057] vconsole.keymap=us$([-x / usr / sbin / rhcrashkernel-param] && / usr / sbin / rhcrashkernel-param||:) rhgb quiet nouveau.modeset=0intel_iommu=o...

Embodiment 2

[0081] Such as figure 2 As shown, the technical solution of the present invention provides a kind of GPU device under Linux KVM straight-through device, including virtualization command adding module 12, GRUB creation module 13, virtual machine creation module 16, GPU straight-through configuration module 17;

[0082] A virtualization command adding module 12 is used to add a virtualization command to GRUB;

[0083] GRUB builds module 13, is used for setting up new GRUB;

[0084] A virtual machine creation module 16, configured to create a virtual machine;

[0085] GPU pass-through configuration module 17, configured to configure GPU pass-through by viewing detailed information of the virtual machine. Through the virtual technology, the GPU device is directly connected to the KVM through the physical machine, which makes the GPU device practical and diversified, reduces the resource idle time of the GPU device, and increases the utilization rate of the GPU device.

Abstract

The invention provides a direct connection method and device for GPU equipment under a Linux KVM. The method comprises the following steps of adding a virtualization command to a GRUB; establishing anew GRUB; creating a virtual machine; and configuring the GPU direct connection. The GPU equipment is directly connected to the KVM through the physical machine through the virtual technology, so thatthe GPU equipment is practical and diversified, the resource idle time of the GPU equipment is shortened, and the utilization rate of the GPU equipment is increased.

Description

technical field [0001] The invention belongs to the technical field related to GPU, and in particular relates to a direct connection method and device of GPU equipment under Linux KVM. Background technique [0002] Graphics processing unit (English: Graphics Processing Unit, abbreviation: GPU), also known as display core, visual processor, display chip, is a kind of microprocessor that specializes in image computing work on game consoles, personal computers, workstations and some mobile devices. device. The purpose of the graphics processor is to convert and drive the display information required by the computer system, and provide line scan signals to the display to control the correct display of the display. One of the important equipment. [0003] Virtualization is when computers run on a virtual basis rather than a real one. It is a solution to simplify management and optimize resources. Virtualization technology can expand the capacity of hardware and simplify the pr...
