It will be apparent that the described embodiments are only some, but not all, embodiments of the application. All other embodiments, based on the examples herein, which are within the scope of the application as defined by the claims, will be within the scope of the application as defined by the claims.

Fig. 1 is a flow chart of a method for adapting a multi-type graphics card driver based on a virtualization technology according to an embodiment of the present application, referring to fig. 1, the method may include the following steps:

s101, determining the ID of the target display card.

Specifically, in a specific application scenario of cloud desktop, cloud rendering and cloud game, a plurality of data centers are involved, each data center is correspondingly provided with a machine room, hardware such as a server is deployed in the data centers, and programs or software related to a virtual machine, such as software running the virtual machine, are deployed on the server.

In a scenario involving a cloud desktop, for example, the desktop is typically published externally by way of a virtualized template and graphics card pass-through. In the process of the transparent transmission of the display card or after the transparent transmission is finished, the virtual machine needs to operate the transparent transmission of the display card, and the corresponding display card drive is needed to drive the display card.

In the above application scenario, when determining the target video card ID, any one of the entity video cards included in the server of the data center may be used as the target video card ID.

S102, configuring a target display card driver in a preset virtual machine.

And the target display card drives a display card with the ID of the target display card.

After determining the target video card ID, configuring a target video card driver corresponding to the target video card ID on the virtual machine, namely configuring a driver capable of driving the video card with the ID as the target video card ID on the virtual machine so as to ensure that the video card with the ID as the target video card ID can run on the virtual machine.

S103, modifying a configuration file in the preset virtual machine through the preset virtualization component.

Specifically, through a preset virtualization component, a configuration file in a preset virtual machine is modified, so that when the preset virtual machine carries out video card transparent transmission, the actual ID of the video card in the transparent transmission process is determined as a target video card ID, and the transparent transmission video card is driven through the target video card.

In some embodiments, the xml configuration file of the virtual machine may be modified by a virsh command of a virtualized component such as libvirt, thereby implementing quick and accurate configuration modification of the virtual machine.

The above procedure for modifying xml configuration files of a virtual machine by a virsh command of a virtualized component such as libvirt will be described in detail in a complete embodiment:

first, the first step: and determining the ID of the target display card, for example, planning the ID of the fixed display card device to be 10de:21c4.

Then, the second step: editing virtual machine configuration by virtualized component libvirt: virsh edit instance-000001. For example, the modification of the configuration file in the virtual machine is realized through the following code files, so that when the virtual machine passes through the display cards, all the display card IDs are determined to be 10de:21c4.

The method comprises the following steps:

<qemu:commandline>

<qemu:arg value＝'-set'/>

<qemu:argvalue＝'device.hostdev0.x-pci-vendor-id＝0x10de'/>

<qemu:arg value＝'-set'/>

<qemu:argvalue＝'device.hostdev0.x-pci-device-id＝0x21c4'/>

</qemu:commandline>

and a third step of: the virtual machine is restarted and the RTX1660s graphics card driver is installed, and then the virtual machine is templated.

Fourth step: and releasing the virtual machines based on the mode of the template and the graphics card transmission, wherein each virtual machine needs to execute the second step operation and then is started. Therefore, different types of display cards at the bottom layer are shielded, and the situation that the corresponding display cards are installed in the virtual machine for driving all the different types of display cards in a transparent way is not needed.

It should be noted that, when the display cards are matched and driven, the display card IDs are used for identification in the prior art, that is, different types of display cards have different display card IDs, and when the display cards are matched and driven, different display card drives are matched for different display card IDs, so that various display cards perfectly run under the driving of the respective drives.

In practical application, because the related computing tasks are different, the computing of the cloud desktop, the cloud rendering, the cloud game and the like in the application does not need some special functions of the display card, namely only the display card is needed to realize some basic functions thereof, so the requirements on the perfection degree of the display card driving to the operation of the display card are not high. Therefore, the calculation task can be realized by driving different types of display cards through the set target display card driver.

In the application, under the scenes of a high-performance cloud desktop and the like, by combining a virtualization technology (such as libvirt, qemu-kvm), when the graphics card is transmitted, a fixed graphics card device id is virtualized in a virtualization layer so as to achieve the diversity of shielding the underlying graphics card, so that a virtual machine operating system only recognizes the fixed graphics card device id to achieve the model of the fixed graphics card in the virtual machine (the graphics card device id can identify the model of the graphics card, for example, 10de:21c4 identifies the-Geforce GTX 1660 SUPER-type graphics card), and the virtual machine operating system only needs to install a graphics card driver of RTX1660s in a virtual machine template so as to achieve the purpose of shielding the type of the underlying graphics card, and reduce the working dimension of the adaptive graphics card driver installation, no matter which the graphics card is transmitted into the virtual machine.
