Description

Technical Field

[0001] The embodiments of the present specification relate to the field of computer technology, and in particular to a virtual machine management method. Background Art

[0002] With the rapid development of computer technology, secure containers have been widely used. At present, secure containers have been applied to many project scenarios in the cloud native field and have become an indispensable basic component. A secure container is a container that supports kernel isolation technology. Compared with ordinary containers, it comes with its own kernel. Since secure containers are based on hardware virtualization technology, each container or container group has an independent operating system kernel, so a control channel is required to complete some virtual machine management tasks, such as adding and deleting devices, configuring resource elasticity, etc. The traditional virtual machine manager (VMM, Virtual Machine Manager) needs to complete the corresponding operations through the user-state agent of the client in the virtualization environment. However, in the cloud native environment, the user-state agent is used to complete the management of the virtual machine, the operation link is long, and operations such as hot-swappable devices are inconvenient to perform in the user state. Therefore, an effective solution is urgently needed to solve the above problems. Summary of the invention

[0072] Many specific details are described in the following description to facilitate a full understanding of this specification. However, this specification can be implemented in many other ways than those described herein, and those skilled in the art can make similar generalizations without violating the connotation of this specification, so this specification is not limited to the specific implementation disclosed below.

These terms are only used to distinguish the same type of information from each other. For example, without departing from the scope of one or more embodiments of this specification, the first may also be referred to as the second, and similarly, the second may also be referred to as the first. Depending on the context, the word "if" as used herein may be interpreted as "at the time of" or "when" or "in response to determining".

[0075] First, the terms involved in one or more embodiments of this specification are explained.

[0076] A virtual machine (VM) is a complete computer system that is simulated by software and has complete hardware system functions and runs in a completely isolated environment. That is, through the combined use of software and hardware, a program running environment isolated from the host machine is created.

[0077] The guest kernel refers to the operating system kernel of the client in a virtualized environment, where guest is the client in the virtualized environment and kernel is the operating system kernel.

[0078] Virtual Machine Manager (VMM) refers to the manager of virtual machines in a virtualized environment.

[0079] In this specification, a virtual machine management method is provided. This specification also involves a client kernel, a virtual machine manager, a computing device, a virtual machine management system, and a computer-readable storage medium, which are described in detail one by one in the following embodiments.

[0080] Figure 1 A flowchart of a virtual machine management method provided according to an embodiment of the present specification is shown, which is applied to a client kernel, wherein the client kernel is configured with a kernel server and a first direct interface, and specifically includes the following steps.

[0081] Step 102: The kernel server receives a virtual machine management request sent by a management client in the virtual machine manager through a second direct connection interface through the first direct connection interface, and the client kernel is connected to the virtual machine manager through the first direct connection interface and the second direct connection interface.

[0082] Specifically, the client kernel refers to the operating system kernel of the client in the virtualization environment, such as guestkernel; the kernel server refers to the server in the client kernel, which can be an upcall server, such as upcallserver, that is, a user-mode agent in the client, used to execute external related instructions; the virtual machine manager refers to the manager of the virtual machine, that is, VMM; the management client refers to the client in the virtual machine manager, which can be an upcall client, such as upcall client; the kernel server and the management client constitute a client-server communication architecture, that is, C / S architecture (Client-Server architecture); the first direct interface and the second direct interface are both interfaces based on the vsock protocol, where vsock is a way to enable direct communication between applications of a host (host) and a client (guest), that is, the first direct interface can be a vsock driver interface, and the second direct interface can be a vsock backend interface; the virtual machine management request is only a request generated for managing the virtual machine, such as adding devices, deleting devices, configuring resource elasticity and other management.

[0083] In actual applications, when managing and controlling virtual machines, users or operators will manage virtual machines through the virtual machine manager of the virtual machine, for example, by inputting the management program or language for the virtual machine in the virtual manager through keyboard and mouse operations. The virtual manager mainly generates virtual machine management requests based on user input through the management client. Since the client kernel is required to execute the management of the virtual machine, and the main execution part of the client kernel is the kernel server, it is necessary to transmit the virtual machine management request to the kernel server, that is, the management client transmits the generated virtual machine management request to the second direct connection interface. Based on the fact that the second direct connection interface can be directly connected to the first direct connection interface, the second direct connection interface transmits the virtual machine management request to the first direct connection interface, and then the first direct connection interface transmits the virtual machine management request to the kernel server.

[0084] For example, if a device in a virtual machine needs to be deleted, the management client upcallclient in the virtual machine manager VMM transmits the virtual machine management request of "deleting a device in the virtual machine" to the vsock backend interface; then the vsock backend interface sends the virtual machine management request to the vsock driver interface; and then the vsock driver interface sends the virtual machine management request to the kernel server upcall server.

[0085] In order to ensure the effectiveness of the transmission of the virtual machine management request and further improve the efficiency of the virtual machine management, it is necessary to establish a connection between the kernel server and the management client before the management client sends the virtual machine management request, that is, before the kernel server receives the virtual machine management request sent by the management client in the virtual machine manager through the second direct connection interface through the first direct connection interface, it also includes:

[0086] The kernel server receives, through the first direct connection interface, a connection request sent by the management client through the second direct connection interface;

[0087] The kernel server generates a connection result based on the connection request, and sends the connection result to the virtual machine manager through the first direct connection interface.

[0088] Specifically, a connection request refers to a request generated by a management client to establish a connection with a kernel server. The request may include an identifier of the management client, such as the ID address of the management client, and may also include an identifier of the kernel server, such as the ID address of the kernel server. A connection result refers to a result of agreeing to or rejecting the connection generated by the kernel server based on the connection request, that is, a successful connection or a failed connection.

[0089] In actual applications, a short connection is used between the management client and the kernel server. Each time before the management client sends a virtual machine management request, it needs to establish a connection with the kernel server: the management client automatically generates a connection request, which is then sent to the client kernel by the second direct connection interface. The first direct connection interface of the client kernel is responsible for receiving the connection request and then transmitting the connection request to the kernel server. The kernel server parses the connection request and then determines whether to agree to the connection, that is, generates a connection result. Furthermore, the first direct connection interface sends the connection result to the virtual machine manager, that is, to the second direct connection interface, and then the second direct connection interface sends the connection result to the management client.

[0090] For example, the management client upcall client in the virtual machine manager VMM generates a connection request and transmits it to the vsock backend interface; then the vsock backend interface sends the connection request to the vsock driver interface; then the vsock driver interface sends the connection request to the kernel server upcall server. The kernel server upcall server then parses the connection request, generates a connection result, transmits the connection result to the vsock backend interface through the vsock driver interface, and then the vsock backend interface sends the connection request to the management client upcallclient.

[0091] Under the request of successful connection, the management client will send the virtual machine management request to the kernel server through the second direct connection interface, that is, the kernel server receives the virtual machine management request sent by the management client in the virtual machine manager through the second direct connection interface through the first direct connection interface. The specific implementation process can be as follows:

[0092] When the connection result is successful, the kernel server receives, through the first direct connection interface, a virtual machine management request sent by the management client in the virtual machine manager through the second direct connection interface.

[0093] It should be noted that only when the management client and the core server are successfully connected, can the management client send a virtual machine management request to the core server. In this way, the success rate of sending virtual machine management requests can be increased, and the efficiency of virtual machine management can be further improved.

[0094] In addition, before the kernel server receives the virtual machine management request, it is necessary to start the kernel server, that is, before the kernel server receives the virtual machine management request sent by the management client in the virtual machine manager through the second direct connection interface through the first direct connection interface, it also includes:

[0095] Receiving a state of the virtual machine manager;

[0096] When the state of the virtual machine manager is turned on, the kernel server is started.

[0097] Specifically, the state of the virtual machine manager refers to whether the virtual machine manager is turned on.

[0098] In actual applications, before starting the kernel server, you need to start the virtual machine manager and the client kernel first, that is, when the client kernel receives the status of the virtual machine manager and the status is turned on, the kernel server is started; when the status is not started, the client kernel does not start the kernel server.

[0099] It should be noted that starting the kernel server may be that the client kernel generates a startup instruction when the virtual machine manager is turned on, thereby starting the kernel server; or the client kernel automatically triggers and starts the kernel server when the virtual machine manager is turned on.

[0100] Step 104: The kernel server manages the virtual machine based on the virtual machine management request and generates a virtual machine management result.

[0101] On the basis that the kernel server receives the virtual machine management request sent by the management client through the second direct connection interface through the first direct connection interface, the kernel server further manages the virtual machine based on the virtual machine management request and generates a virtual machine management result.

[0102] Specifically, the virtual machine management result refers to the result of managing the virtual machine, such as management success or management failure. When management fails, it may also include the path or reason of the management failure, such as insufficient space.

[0103] In actual applications, after receiving a virtual machine management request, the kernel server parses the virtual machine management request, determines the virtual machine management instruction, and then operates according to the virtual machine management instruction to manage the virtual machine. After the management is completed, it determines whether the management is successful, that is, generates a virtual machine management result.

[0104] For example, if the virtual machine management request is to add device A, the kernel server upcall server parses the virtual management request, determines the management instruction for adding device A, and then adds device A to the virtual machine. If the addition is successful, a first virtual machine management result is generated; if it fails, the reason for the failure to add device A is determined, and a second virtual machine management result is generated.

[0105] Step 106: The kernel server sends the virtual machine management result to the virtual machine manager through the first direct connection interface.

[0106] On the basis that the kernel server manages the virtual machine based on the virtual machine management request and generates the virtual machine management result, the kernel server further sends the virtual machine management result to the virtual machine manager through the first direct interface.

[0107] In actual applications, after the kernel server generates the virtual machine management result, the first direct connection port sends the virtual machine management result to the virtual machine manager, that is, to the second direct connection port, and then the second direct connection port sends the virtual machine management result to the management client, so that the management client can notify the user or operator of the virtual machine management result.

[0108] Continuing with the above example, the kernel server upcall server transmits the generated first virtual machine management result or the second virtual machine management result to the vsock driver interface, and then the vsock driver interface transmits the first virtual machine management result or the second virtual machine management result to the vsock backend interface, and then the vsock backend interface sends the first virtual machine management result or the second virtual machine management result to the management client upcall client.

[0109] The virtual machine management method provided in this specification is as follows: first, the management client in the virtual machine manager sends a virtual machine management request through the second direct connection interface, and the kernel server receives the virtual machine management request through the first direct connection interface; the client kernel is connected to the virtual machine manager through the first direct connection interface and the second direct connection interface; then the kernel server manages the virtual machine based on the virtual machine management request and generates a virtual machine management result; the kernel server sends the virtual machine management result to the management client through the first direct connection interface. Based on the first direct connection interface and the second direct connection interface, an efficient management channel is provided; the kernel server in the user state is moved into the client kernel to form a kernel server in the kernel state, shortening the link between the management client and the client kernel, thereby shortening the management link of the virtual machine, increasing the stability of the client kernel, and performing privileged operations based on the kernel state of the kernel server; thereby improving the efficiency of virtual machine management.

[0110] In addition, virtual machine management requests are processed directly in the kernel server of the kernel server, which greatly shortens the management link; the kernel server is included in the kernel server, and the user does not need to install the kernel server; the kernel server is a kernel thread and will not be accidentally killed by the user; the kernel server is in the kernel state and can perform related privileged operations, such as hot-plugging devices, memory, and central processing units; a first direct connection interface and a second direct connection interface are provided to establish a fast and stable management channel between the virtual machine manager and the client kernel.

[0111] Figure 2 A flowchart of another virtual machine management method provided according to an embodiment of the present specification is shown, which is applied to a virtual machine manager, wherein the virtual machine manager is configured with a management client and a second direct connection interface, and specifically includes the following steps.

[0112] Step 202: The management client generates a virtual machine management request according to the received virtual machine management instruction.

[0113] Specifically, the virtual machine manager refers to the manager of the virtual machine, namely VMM; the management client refers to the client in the virtual machine manager, which can be an upcall client, such as an upcall client; the virtual machine management instruction refers to the instruction generated according to the management operation of the virtual machine by the user or operator; the virtual machine management request is only the request generated for the management of the virtual machine, such as adding devices, deleting devices, configuring resource elasticity and other management.

[0114] In actual applications, when managing and controlling virtual machines, users or operators will manage virtual machines through the virtual machine manager of the virtual machine, for example, by inputting the management program or language for the virtual machine in the virtual manager through keyboard and mouse operations. The management client in the virtual manager will receive the virtual machine management instructions corresponding to the user's input, and further, the management client processes the virtual machine management instructions, such as packaging and encoding, to generate virtual machine management instructions.

[0115] For example, if a device in a virtual machine needs to be added, the management client upcallclient in the virtual machine manager VMM generates a virtual machine management request of "adding a device in a virtual machine" according to the virtual machine management instruction corresponding to the operation of "adding a device in a virtual machine".

[0116] Since the management of virtual machines requires the client kernel to execute, and the main execution part of the client kernel is the kernel server, it is necessary to transmit the virtual machine management request to the kernel server. In order to ensure the effectiveness of the transmission of virtual machine management requests and further improve the efficiency of virtual machine management, it is necessary to establish a connection between the kernel server and the management client before generating the virtual machine management request, and then generate the virtual machine management request after the connection is successfully established. The specific implementation process can be as follows:

[0117] The management client generates a connection request, and sends the connection request to the client kernel through the second direct connection interface;

[0118] The management client receives, through the second direct connection interface, a connection result sent by the kernel server through the first direct connection interface, where the connection result is generated by the kernel server based on the connection request;

[0119] The management client identifies the connection result;

[0120] When the connection result is successful, the management client generates a virtual machine management request according to the received virtual machine management instruction.

[0121] Specifically, a connection request refers to a request generated by a management client to establish a connection with a kernel server, and the request may include an identifier of the management client, such as an ID address of the management client, and may also include an identifier of the kernel server, such as an ID address of the kernel server; the first direct connection interface and the second direct connection interface are both interfaces based on the vsock protocol, wherein vsock is a method for enabling applications to communicate directly between a host and a client, that is, the first direct connection interface may be a vsock driver interface, and the second direct connection interface may be a vsock backend interface; the kernel server refers to a server in a client kernel, and may be an upcall server, such as an upcall server, that is, a user-mode agent in a client for executing external related instructions; the kernel server and the management client constitute a client-server communication architecture, that is, a C / S architecture (Client-Server architecture); the connection result refers to a result of agreeing to connect or rejecting the connection generated by the kernel server according to the connection request, that is, a successful connection or a failed connection.

[0122] In actual applications, a short connection is used between the management client and the kernel server. Before the management client sends a virtual machine management request each time, it needs to establish a connection with the kernel server: the management client automatically generates a connection request, which is then sent to the client kernel by the second direct connection interface. The first direct connection interface of the client kernel is responsible for receiving the connection request, and then transmitting the connection request to the kernel server. The kernel server parses the connection request, and then determines whether to agree to the connection, that is, to generate a connection result. Further, the first direct connection interface sends the connection result to the virtual machine manager, that is, to the second direct connection interface, and then the second direct connection interface sends the connection result to the management client. After receiving the connection result, the management client determines whether the connection is successful, that is, to identify the connection result. If the connection is successful, the management client generates a virtual machine management request according to the received virtual machine management instruction. In addition, after the management client successfully connects to the kernel server, it can immediately send a virtual machine management request, or it can send a virtual machine management request at any time after the connection is successful.

[0123] For example, the management client upcall client in the virtual machine manager VMM generates a connection request and transmits it to the vsock backend interface; then the vsock backend interface sends the connection request to the vsock driver interface; then the vsock driver interface sends the connection request to the kernel server upcall server. The kernel server upcall server then parses the connection request, generates a connection result, transmits the connection result to the vsock backend interface through the vsock driver interface, and then the vsock backend interface sends the connection request to the management client upcall client. The management client upcall client identifies the connection result. If the connection is successful, the management client upcall client generates a virtual machine management request according to the received virtual machine management instruction.

[0124] In order to ensure that the virtual machine management request can be sent and further guarantee the management efficiency of the virtual machine, if the management client fails to establish a connection with the kernel server, the management client will generate a connection request again and try to establish a connection with the kernel server again, that is:

[0125] When the connection result is a connection failure, the step of generating a connection request by the management client is performed.

[0126] In actual applications, when the management client fails to establish a connection with the kernel server, that is, when the connection result is a connection failure, the management client will continue to try to establish a connection with the kernel server until the kernel server returns a connection result of a successful connection.

[0127] In addition, before the management client generates a virtual machine management request, it is necessary to start the management client, that is, before the management client generates a virtual machine management request according to the received virtual machine management instruction, it also includes:

[0128] Receiving a state of the client kernel;

[0129] When the client kernel is in the enabled state, the management client is started.

[0130] Specifically, the state of the client kernel refers to whether the client kernel is enabled.

[0131] In actual applications, before starting the management client, you need to start the virtual machine manager and the client kernel first, that is, when the virtual machine manager receives the status of the client kernel machine and the status is turned on, the management client is started; when the status is not started, the virtual machine manager does not start the management client.

[0132] It should be noted that starting the management client may be that the virtual machine manager generates a startup instruction when the client kernel is in the on state, thereby starting the management client; or the virtual machine manager automatically triggers and starts the management client when the client kernel is in the on state.

[0133] Step 204: The management client sends the virtual machine management request to the client kernel through the second direct connection interface, so that the kernel server in the client kernel receives the virtual machine management request through the first direct connection interface, and the client kernel is connected to the virtual machine manager through the first direct connection interface and the second direct connection interface.

[0134] On the basis that the management client generates a virtual machine management request according to the received virtual machine management instruction, the management client further sends the virtual machine management request to the client kernel through the second direct connection interface.

[0135] Specifically, the first direct interface and the second direct interface are both interfaces based on the vsock protocol, wherein vsock is a method for enabling direct communication between applications of a host and a guest, that is, the first direct interface may be a vsock driver interface, and the second direct interface may be a vsock backend interface; the kernel server refers to a server in the client kernel, and may be an upcall server, such as an upcall server, that is, a user-mode agent in the client, for executing external related instructions; the kernel server and the management client constitute a client-server communication architecture, that is, a C / S architecture (Client-Server architecture).

[0136] In actual applications, the management client transmits the generated virtual machine management request to the second direct connection interface. Based on the fact that the second direct connection interface can be directly connected to the first direct connection interface, the second direct connection interface passes the virtual machine management request to the first direct connection interface, and then the first direct connection interface transmits the virtual machine management request to the kernel server.

[0137] For example, the management client upcall client in the virtual machine manager VMM transmits the virtual machine management request of "adding a device in the virtual machine" to the vsock backend interface; then the vsock backend interface sends the virtual machine management request to the vsock driver interface; and then the vsock driver interface sends the virtual machine management request to the kernel server upcall server.

[0138] Step 206: The management client receives, through the second direct connection interface, the virtual machine management result sent by the kernel server through the first direct connection interface.

[0139] On the basis that the management client sends the virtual machine management request to the client kernel through the second direct connection interface, the management client further receives the virtual machine management result through the second direct connection interface.

[0140] In actual applications, after receiving a virtual machine management request, the kernel server parses the virtual machine management request, determines the virtual machine management instruction, and then operates according to the virtual machine management instruction to manage the virtual machine. After the management is completed, it is determined whether the management is successful, that is, the virtual machine management result is generated. After that, the first direct connection interface sends the virtual machine management result to the virtual machine manager, that is, to the second direct connection interface, and then the second direct connection interface sends the virtual machine management result to the management client, so that the management client can notify the user or operator of the virtual machine management result.

[0141] For example, if the virtual machine management request is to delete device B, the kernel server upcall server will parse the virtual management request, determine the management instruction to delete device B, and then delete device B in the virtual machine. If the deletion is successful, the first virtual machine management result is generated; if it fails, the reason for the failure to delete device B is determined, and the second virtual machine management result is generated. The kernel server upcall server transmits the generated first virtual machine management result or second virtual machine management result to the vsock driver interface, and then the vsock driver interface transmits the first virtual machine management result or second virtual machine management result to the vsock backend interface, and then the vsock backend interface sends the first virtual machine management result or second virtual machine management result to the management client upcall client.

Based on the first direct connection interface and the second direct connection interface, an efficient management channel is provided; the kernel server in the user state is moved into the client kernel to form a kernel server in the kernel state, shortening the link between the management client and the client kernel, thereby shortening the management link of the virtual machine, increasing the stability of the client kernel, and performing privileged operations based on the kernel state of the kernel server; thereby improving the efficiency of virtual machine management.
