Description
Technical Field
The embodiment of the disclosure relates to the technical field of image transmission, and in particular relates to a virtual machine image transmission method, electronic equipment and a storage medium.
Background
The basic structure of the existing cloud desktop system can be referred to fig. 1. As shown in fig. 1, the cloud desktop system is based on a ten-thousand-image VGTP image transfer protocol (VGTP is a real-time image compression transmission protocol, is completely independent and autonomous and controllable, has core technologies such as multiple encoders, progressive encoding, visual lossless image transfer, network bandwidth adaptation, QoS, and the like, and supports audio transmission and a reverse control channel), and mainly includes a zero terminal (a built-in VGTP-R terminal, referred to as an R terminal for short) and a cloud server terminal (a built-in VGTP-S terminal, referred to as an S terminal for short). The R end is used for receiving an image from a cloud desktop, transmitting local mouse and keyboard information to the cloud end in a reverse direction, and injecting the information into a cloud desktop corresponding to the current R end by the cloud end, wherein the cloud desktop is generated by virtual machines/physical machines (VM/PM) distributed to a current zero terminal by a cloud server; the S end is an image acquisition and coding module running in the cloud virtual OS and is responsible for performing an injection function of user input data. The cloud server is generally based on an IAAS (Infrastructure as a Service) architecture, and is a server with a strong virtual host, which may provide management functions of multiple virtual machines through hypervisor (a middle layer software running between a physical server and an operating system, which may allow multiple operating systems and applications to share a set of basic physical hardware), and provide a running hardware environment for a virtual machine/a physical machine VM/PM.
The cloud desktop system has been widely used in fields such as offices, games, and the like. In some scenarios, one virtual machine user needs to send the whole desktop image or a certain application window of the user to another virtual machine user, for example, one game user pushes the game picture of the user to another game user, so as to jointly complete a multi-player battle game. In the prior art, a sending end virtual machine generally sends an image to a receiving end virtual machine through a network aiming at the scene, but in a real scene, the position relations of the virtual machines at the two sending and receiving ends are various, and the virtual machines are transmitted through the network, so that not only can the waste of resources be caused, but also the transmission efficiency can be reduced, and the technical improvement is needed.

Detailed Description
Example embodiments will now be described more fully with reference to the accompanying drawings. Example embodiments may, however, be embodied in many different forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of example embodiments to those skilled in the art. The described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.
Furthermore, the drawings are merely schematic illustrations of the present disclosure and are not necessarily drawn to scale. The same reference numerals in the drawings denote the same or similar parts, and thus their repetitive description will be omitted. Some of the block diagrams shown in the figures are functional entities and do not necessarily correspond to physically or logically separate entities. These functional entities may be implemented in the form of software, or in one or more hardware modules or integrated circuits, or in different networks and/or processor devices and/or microcontroller devices.
First, in this exemplary embodiment, a virtual machine image transmission method is provided, and as shown in fig. 3, the method may include the following steps:
step S101, a first virtual machine initiates an image transmission request to a second virtual machine and obtains server information of the second virtual machine;
step S102, the first virtual machine receives server information of the second virtual machine, and judges the position relation between the second virtual machine and the first virtual machine according to the server information of the second virtual machine;
step S103, the first virtual machine determines an image transmission method according to the position relation between the second virtual machine and the first virtual machine;
and step S104, the first virtual machine transmits the image to the second virtual machine according to the determined image transmission method.
By the method, when the first virtual machine sends the image to the second virtual machine, the server information of the second virtual machine needs to be acquired, and after the server information of the second virtual machine is acquired, the position relationship between the two virtual machines is judged according to the information, wherein different position relationships correspond to different image transmission methods. By the virtual machine image transmission method, the optimal transmission scheme can be selected according to the position relation between the two virtual machines in the scene of image transmission between the two virtual machines, so that network resources are saved, and the transmission efficiency is greatly improved.
Hereinafter, the respective steps of the above-described method in the present exemplary embodiment will be described in more detail with reference to fig. 2 to 10.
In step S101, the first virtual machine is located on a first cloud server, the second virtual machine is located on a second cloud server, the server information of the second virtual machine is the identification information of the second cloud server, and the first virtual machine also has its own server information, which is the identification information of the first cloud server. Each virtual machine has its own server information, and is the identification information of its corresponding cloud server, which is used to distinguish the virtual machines. The identification information may be, for example, an IP address, a MAC address, etc., but is not limited thereto.
In some embodiments, referring to fig. 4, the step S101 further includes the following steps:
step S201, the first virtual machine stores identification information of a first cloud server where the first virtual machine is located. Specifically, for example, the cluster 1 may include a plurality of servers (11, 12 · 1n), and the cluster 2 also includes a plurality of servers (21, 22 · 2n), where the first virtual machine is in the cluster 1, and the first virtual machine needs to store the identification information of its own server, and may store the identification information to the local or cloud.
Step S202, the first virtual machine stores identification information of other cloud servers in the cluster where the first cloud server is located. Specifically, as described in the foregoing steps, the first virtual machine stores identification information of cloud servers corresponding to other virtual machines in the cluster 1 except the first virtual machine, so as to serve as a basis in subsequent determination of the location relationship.
The position relationship between the first virtual machine and the second virtual machine generally includes the following three cases:
in step S301, if the identification information of the cloud server where the second virtual machine is located is the same as the identification information of the cloud server where the first virtual machine is located.
Step S302, it is determined that the second virtual machine and the first virtual machine are located on the same cloud server.
In case 2, in some embodiments, please refer to fig. 6, the step S102 may further include the following steps:
step S401, if the identification information of the cloud server where the second virtual machine is located is different from the identification information of the cloud server where the first virtual machine is located, but the identification information of the cloud server where the second virtual machine is located is the same as the identification information of the other cloud servers in the cluster where the cloud server where the first virtual machine is located;
step S402, determining that the second virtual machine and the first virtual machine are respectively located in different cloud servers in the same cluster.
In some embodiments, referring to fig. 7, the step S102 may further include the following steps:
in case 3, in step S501, if the identification information of the cloud server where the second virtual machine is located is different from the identification information of all cloud servers in the cluster where the cloud server where the first virtual machine is located;
step S502, determining that the second virtual machine and the first virtual machine are located in different clusters on the cloud server.
For the three position relationships, the method correspondingly comprises the following three image transmission modes:
in the method 1, when the position relationship between the first virtual machine and the second virtual machine is the case 1, in some embodiments, referring to fig. 8, the step S104 may include the following steps:
step S601, opening an intercommunication channel between the first virtual machine and the second virtual machine, and directly performing image transmission between the first virtual machine and the second virtual machine. Image transmission among the virtual machines is not needed through the network, and network resources are saved.
In mode 2, when the position relationship between the first virtual machine and the second virtual machine is case 2, in some embodiments, referring to fig. 9, the step S104 may further include the following steps:
step S701, the first virtual machine sends image information to a switch;
step S702, the switch receives and sends the image information to a cloud server where the second virtual machine is located;
step S703, searching for the second virtual machine in a cluster in which a cloud server in which the second virtual machine is located;
step S704, sending the image information to the second virtual machine.
In manner 3, when the position relationship between the first virtual machine and the second virtual machine is case 3, in some embodiments, referring to fig. 10, the step S104 may further include the following steps:
step S801, the first virtual machine performs image transmission to the second virtual machine through a network.
In any of the above embodiments, the image transmitted from the first virtual machine to the second virtual machine may be divided into two cases: firstly, the first virtual machine sends the whole picture of the desktop of the first virtual machine to the second virtual machine, and a receiving end of the second virtual machine can carry out any operation on the whole first virtual machine and has all execution authorities; secondly, the first virtual machine sends a picture of a certain software window in the first virtual machine to the second virtual machine, and a receiving end of the second virtual machine can perform any operation in the window, and has all execution authorities for the operation in the window, such as a game window, a video window, a design software window, and the like.
And the second virtual machine receives and decodes the image information sent by the first virtual machine, and displays the image. Specifically, in some embodiments, after the first virtual machine transmits the image information to the second virtual machine in the determined image transmission manner, the second virtual machine first decodes the image information and then performs rendering display. For the second virtual machine, not only the image sent by the first virtual machine can be directly viewed, but also the image sent by the first virtual machine can be reversely controlled.
With regard to the apparatus in the above-described embodiment, the specific manner in which each module performs the operation has been described in detail in the embodiment related to the method, and will not be elaborated here.
