Firstly, explaining some concepts related in an application updating method, a computing device and a computing system of a virtual machine provided in the embodiments of the present application:

virtual machine: refers to a complete computer system with complete hardware system functions that operates in a completely isolated environment through software simulation. Work that can be done in a physical computer can be done in a virtual machine. When creating a virtual machine in a computer, a part of hard disk and memory capacity of the physical machine are required to be used as the hard disk and memory capacity of the virtual machine. Each virtual machine has an independent hard disk and operating system, and can operate as if a physical machine were used.

In the background art, when updating an application on a virtual machine in a scene without a network or an unstable network, the update of the application fails, so that the success rate of the update of the application is reduced; in order to solve the problem, the embodiment of the application provides an application updating method of a virtual machine, wherein a host machine sends an application identifier of an application to be updated to a target virtual machine which needs to be updated on the host machine through a virtual serial port; and adding the update of the application to be updated in the host machine to a file system of the target virtual machine by the target virtual machine, and finally, updating the application to be updated on the target virtual machine based on the update package by the target virtual machine. In the updating process, the host machine and the target virtual machine running on the host machine are communicated based on the virtual serial port, so that the problem that the updating of the application to be updated fails due to the network problem in the updating process of the application to be updated is avoided, and the success rate of updating the application to be updated on the virtual machine is improved.

The application updating method provided by the embodiment of the application is applied to a management system shown in fig. 1; the management system includes: host 101, host 102, host 103, and management device 104.

The management device 104 is configured to send, to each of the hosts 101 and 103, an identifier of a target virtual machine running on the host and an application identifier of an application to be updated, where, taking the host 101 as an example, the target virtual machine in the host 101 is a virtual machine that needs to be updated by an application from multiple virtual machines running on the host 101. Wherein the management device 104 is respectively connected with the host machine 101 and the host machine 103 through a network; in particular, the management device 104 may be a computing device having processing capabilities such as a server, computer, or the like.

The host 101 is configured to receive an application update request sent by the management device 104, where the application update request includes: the identity of the target virtual machine in the host 101 and the application identity of the application to be updated; then, the host 101 sends the application identifier of the application to be updated to the target virtual machine through the virtual serial port between the host and the target virtual machine, so that the target virtual machine updates the application to be updated.

It should be noted that, the virtual machines (e.g., virtual machine 1012) on the host 101 are all running on the operating system of the host 101, and the virtual machine 1012 communicates with the host 101 based on virtual serial ports.

The host machine 101 is configured to run a plurality of virtual machines such as a virtual machine 1011, a virtual machine 1012, a virtual machine..and a virtual machine 101x, and the plurality of virtual machines may be virtual machines whose operating system is Windows or virtual machines whose operating system is linux. A plurality of applications exist on any one of the plurality of virtual machines; taking the virtual machine 1012 as an example, a video application, a reading application, and a music application exist on the virtual machine 1012. In particular, the host machine 101 may be a desktop computer, a notebook, a server, or the like, computing device having computing and storage capabilities.

It should be understood that, the descriptions of the host 102 and the host 103 are similar to those of the host 101, and detailed descriptions of the host 102 and the host 103 are referred to the descriptions of the host 101 and are not repeated herein.

It should be noted that, the application updating method provided in the embodiment of the present application is applied to a scenario of updating and upgrading an application of a virtual machine in the management system; the above management system is described by taking a host machine including a host machine 101 and a host machine 103 as an example, and in practical application, the management system may include at least one host machine; similarly, the management system is described by taking a host machine running a plurality of virtual machines as an example, and in practical application, the host machine may run at least one virtual machine.

Illustratively, FIG. 2 is a schematic diagram of a computing device hardware architecture of host 101, host 102, or host 103. The computing device may be a high-density server, a rack server, a high-performance server, a GPU (graphics processing unit) server, or the like.

The hardware portion of the computing device includes a processor (central processing unit, CPU), an out-of-band controller, and a memory, among others. The software portion mainly includes an out-of-band management module, and an Operating System (OS).

Wherein the out-of-band management module operates within the out-of-band controller and the OS and BIOS operate within the processor (as shown in fig. 2). The out-of-band management module may be a management unit of a non-business module. For example, the out-of-band management module may remotely maintain and manage the computing device via a dedicated data channel. The out-of-band management module is completely independent of the operating system of the computing device and may communicate with the OS through an out-of-band management interface of the computing device. Wherein, at least one virtual machine is operated in the OS, specifically comprising: virtual machine_1 to virtual machine_n.

For example, as shown in fig. 3, the system architecture between the virtual machine_1 and the CPU in the host machine for running the OS is shown, where the virtual machine_1 includes an application a, an application B, and a daemon service, and the daemon service is configured to create a virtual serial port between the virtual machine_1 and the CPU when initializing the virtual machine_1, and receive update instructions of the CPU corresponding to the application a and the application B through the virtual serial port; the daemon service is also operable to update application a and application B in response to the update instruction.

An application update service is operated in the CPU and is used for sending the update instruction to the daemon service in the virtual machine_1 through a virtual serial port; the virtual serial port is used for providing a virtual serial port channel for interaction between the virtual machine and the host machine.

By way of example, the out-of-band management module may include a management unit that calculates the operating state of the device, a management system in a management chip outside of the in-band controller, a system management module (system management mode, SMM), and the like. It should be noted that, the embodiments of the present application are not limited to the specific form of the out-of-band management module, and the above is merely exemplary.

The memory, also called internal memory or main memory, is installed in a memory slot on a motherboard of the computing device, and the memory controller communicate through a memory channel (channel).

It should be noted that, the system architecture and the application scenario described in the embodiments of the present application are for more clearly describing the technical solution of the embodiments of the present application, and do not constitute a limitation on the technical solution provided in the embodiments of the present application, and those skilled in the art can know that, with the evolution of the system architecture and the appearance of a new service scenario, the technical solution provided in the embodiments of the present application is also applicable to similar technical problems.

The embodiment of the application provides an application updating method of a virtual machine, as shown in fig. 4, the method includes: S110-S130.

And S110, responding to the application updating request, and sending an application identifier of the application to be updated to the target virtual machine by the host machine through the virtual serial port.

At least one virtual machine is operated on the host machine, and the at least one virtual machine is communicated with the host machine through a virtual serial port; wherein at least one application exists in the at least one virtual machine.

The virtual serial port is a virtual serial port channel which is created by the virtual machine during initialization and used for providing interaction between the virtual machine and the host machine.

The target virtual machine is a virtual machine that needs to update an application on the target virtual machine, for example, it is assumed that a host machine is running with a virtual machine_1 and a virtual machine_2, and when the host machine needs to update an application on the virtual machine_1, the virtual machine_1 is the target virtual machine.

When there are multiple target virtual machines in the host, and the applications to be updated of the multiple target virtual machines are the same, the host sends application identifiers of the applications to be updated to the multiple target virtual machines, respectively, so that the multiple target virtual machines execute the following S120-S130.

When a plurality of target virtual machines exist in the host machine and the corresponding applications to be updated in the target virtual machines are different; the host machine sends application identifiers of the respective corresponding applications to be updated to the plurality of target virtual machines, respectively, so that the plurality of target virtual machines execute the following S120-S130 based on the application identifiers of the respective corresponding applications to be updated.

For example, assuming that a host machine runs with a virtual machine_1 and a virtual machine_2, when the host machine needs to update an application a in the virtual machine_1 and an application B in the virtual machine_2, the virtual machine_1 and the virtual machine_2 are both target virtual machines, and at this time, the host machine sends an application identifier of the application a to the virtual machine_1 and an application identifier of the application B to the virtual machine_2.

It should be noted that, the application update request is a request triggered after a user designates a target virtual machine on the host machine and an application to be updated on the target virtual machine, for indicating to update the application to be updated on the target virtual machine.

In one implementation, the application update request is a request triggered after a user designates a target virtual machine on a host machine and an application to be updated on the target virtual machine; the method specifically comprises the following steps: the user accesses a virtual machine management interface on the host machine, and triggers the application update request after selecting a target virtual machine and an application to be updated on the target virtual machine in the virtual machine management interface; the virtual machine management interface comprises all virtual machines running on the host machine and all applications on each virtual machine in all the virtual machines.

For example, assume that a virtual machine management interface is shown in fig. 5, which includes virtual machine_1 to virtual machine_4 running on a host machine; wherein, each of the virtual machine_1 to the virtual machine_3 comprises an application A and an application B, and each of the virtual machine_4 comprises an application B and an application C. After a user selects an application A in the virtual machine_1, an application B in the virtual machine_3 and an application B and an application C in the virtual machine_4 on the interface, clicking an update button to trigger an application update request, wherein the request comprises an identification of a target virtual machine and an application identification of an application to be updated; the host machine obtains the identification of the target virtual machine (namely, virtual machine_1, virtual machine_3 and virtual machine_4) appointed by the user and the application identification of the application to be updated corresponding to the target virtual machine; namely; the application to be updated of the virtual machine_1 is an application A, the application to be updated of the virtual machine_3 is an application B, and the application to be updated of the virtual machine_4 is an application B and an application C. Then, the host sends the application identifier of the application a to the virtual machine_1, the application identifier of the application B to the virtual machine_3, and the application identifiers of the application B and the application C to the virtual machine_4.

In another implementation manner, the application update request is a request sent by the management device to the host machine after the user designates the target virtual machine and the application to be updated on the management device; the management device is a device for managing the host, and the specific implementation process of the management device is shown in S310-S330, which are not described herein.

Optionally, an application update service is run in the host, and a daemon service is run in each virtual machine in the at least one virtual machine; when the virtual machine where the daemon service is located starts, the virtual serial port is created. The daemon service in each virtual machine interacts with the application update service in the host machine based on the virtual serial port; based on this, the implementation manner of S110 includes: and the application updating service running in the host machine sends the application identification of the application to be updated to the daemon service running in the target virtual machine through the virtual serial port.

It should be noted that, the application update service may be an independent application in the host machine, or may be a functional module in an application (such as VMtools) in the host machine; similarly, the daemon service in the virtual machine may be an independent application or process, or may be a functional module in an application or process (e.g., internal daemon-gum-agent, qga) in the virtual machine.

S120, the target virtual machine adds an update package of the application to be updated in the host machine to a file system of the target virtual machine.

It should be noted that, the update package may be stored in the host machine in advance by the user, or may be sent to the host machine by the management device, and in this embodiment of the present application, the method for obtaining the update package is not limited.

In one implementation manner, the implementation manner of S120 is based on an optical drive of the target virtual machine, and the update package is added to a file system of the target virtual machine, as shown in fig. 6 in conjunction with fig. 4, and the specific implementation process includes: s120a-S120d.

S120a, the target virtual machine sends a mounting notification to the host machine through the virtual serial port.

The mounting notification is used for indicating the host to mount the update package of the application to be updated in the target virtual machine to the CD-ROM of the target virtual machine.

And S120b, the host machine responds to the mounting notification to mount the update package of the application to be updated to the CD-ROM of the target virtual machine.

The specific implementation of S120b includes: the host converts the update package of the application to be updated into an image file (simply referred to as the image file of the update package), and then executes a mount command to mount the image file of the update package into a directory (such as dev/sr 0) corresponding to the CD-ROM of the target virtual machine.

S120c, the host machine sends a successful mounting message to the target virtual machine through the virtual serial port.

The successful message is used to instruct the host to mount the update package to the file directory corresponding to the CD-ROM of the target virtual machine.

And S120d, the target virtual machine responds to the successful mounting message, and an update package of the application to be updated is added into a file system of the target virtual machine from an optical drive of the target virtual machine.

The specific implementation manner of S120d may be that the target virtual machine copies the update package in the optical drive to a file system of the target virtual machine (e.g., a home file directory in the file system) based on a copy command; the target virtual machine may mount the update package in the optical drive to a file system of the target virtual machine based on the mount command. The implementation manner of S120d is not limited in the specific embodiment of the present application.

In another implementation manner, the implementation manner of S120 is to add the update package to the file system of the target virtual machine based on the shared folder between the target virtual machine and the host machine, and in conjunction with fig. 4, as shown in fig. 7, the specific implementation process includes: S120A-S120D.

S120A, the target virtual machine sends an adding notification to the host machine through the virtual serial port.

The addition notification is used for indicating the host to add the update package to a shared folder, wherein the shared folder is a folder which is visible to both the host and the target virtual machine and can be subjected to read-write operation.

And S120B, the host responds to the addition notice to add the update package of the application to be updated to the shared folder.

The specific implementation of S120B may be that the host executes a mount command to mount the update package in the shared folder; the host may execute copy command to copy the update package to the shared folder.

S120C, the host machine sends an addition success message to the target virtual machine through the virtual serial port.

And S120D, the target virtual machine responds to the adding success message, and an update package of the application to be updated is added from the shared file to a file system of the target virtual machine.

It should be noted that, the implementation of the above-mentioned S120C-S120D is similar to that of S120C-S120D, and specific descriptions of S120C-S120D may refer to the above-mentioned related descriptions of S120C-S120D, which are not repeated here.

And S130, the target virtual machine updates the application to be updated based on the update package of the application to be updated.

In one implementation manner, the specific implementation of S130 includes: the target virtual machine updates the application to be updated in a preset updating mode based on an updating packet of the application to be updated; the preset updating mode comprises the following steps: incremental updates or full updates.

The incremental updating is to update the application to be updated based on the difference between the updating package and the application to be updated; the full-volume update is that a target virtual machine firstly uninstalls an application to be updated in the target virtual machine, and then installs the application in an update package of the application to be updated.

It should be noted that, the preset updating manner may be configured in the target virtual machine by the user through the host, or may be sent to the target virtual machine by the management device through the host, and in this embodiment of the present application, the acquiring manner of the preset updating manner is not limited.

In another implementation manner, the specific implementation of S130 includes: and the target virtual machine updates the application to be updated based on the update package of the application to be updated and a preset update strategy. The preset updating strategy comprises the following steps: a real-time update policy, a timed update policy, a polling update policy, or a parallel update policy.

It should be noted that, the preset update policy may be configured in the target virtual machine by the user through the host, or may be sent by the management device to the target virtual machine through the host, and in this embodiment of the present application, the method for obtaining the preset update policy is not limited.

The real-time update policy is used for indicating a policy that when an update package of an application to be updated is added to a file system of a target virtual machine, the target virtual machine immediately updates the application to be updated based on the update package.

The above-mentioned timing update policy is used to indicate a policy that, after adding an update package of an application to be updated to a file system of a target virtual machine, the target virtual machine updates the application to be updated based on the update package only at a preset time point. For example: assuming that the preset time point is 0 point; then, when the target virtual machine acquires the update package at 18 points, the application to be updated is not updated; only when the point reaches 0, the target virtual machine updates the application to be updated based on the update package.

The polling update strategy is used for indicating a strategy that the target virtual machine sequentially updates each application to be updated according to the arrangement sequence of the plurality of applications to be updated under the condition that the plurality of applications to be updated exist in the target virtual machine. For example: assume that the application to be updated present in the target virtual machine includes: application 1 to application 3; at this time, the target virtual machine updates the application 1, updates the application 2 after the update of the application 1 is completed, and updates the application 3 after the update of the application 2 is completed.

The parallel update policy is used for representing a policy that the target virtual machine updates at least two applications to be updated in the plurality of applications to be updated at the same time when the plurality of applications to be updated exist in the target virtual machine.

The method includes the steps that an example is given, 8 applications to be updated exist in a target virtual machine A, and a preset updating strategy of the target virtual machine A is a parallel updating strategy; at this time, the target virtual machine creates a thread pool, and the number of available threads in the thread pool is 4; then, the target virtual machine a allocates an application to be updated to each available thread in the thread pool, so that the target virtual machine a updates the allocated application to be updated. When an idle thread appears in the 4 threads (i.e. the thread has completed updating the allocated applications to be updated), the target virtual machine allocates the 5 th application to be updated (i.e. any one of the applications to be updated which are not updated) to the idle thread, and reciprocates in sequence until the 8 applications to be updated are all completed updating.

Based on the application updating method shown in fig. 4, another application updating method of a virtual machine is provided in the embodiment of the present application, as shown in fig. 8, the method includes: S210-S270.

And S210, responding to the application updating request, and sending an application identifier of the application to be updated to the target virtual machine by the host machine through the virtual serial port.

It should be noted that, the implementation of S210 is similar to the implementation of S110, and specific descriptions of S210 may refer to the related descriptions of S110, which are not repeated herein.

S220, the target virtual machine determines whether the target virtual machine meets preset conditions.

The preset conditions are used for determining the health state of the target virtual machine, and when the target virtual machine meets the preset conditions, the target virtual machine is indicated to be in the health state; and when the target virtual machine does not meet the preset condition, indicating that the target virtual machine is in an unhealthy state. The preset conditions include, but are not limited to: the unused rate of the processor in the target virtual machine is greater than or equal to a first threshold; and/or, the unused rate of the memory in the target virtual machine is greater than or equal to a second threshold; and/or the unused rate of the hard disk in the target virtual machine is greater than or equal to a third threshold.

The first threshold value is larger than or equal to the computing force resource required by the updated application to be updated of the target virtual machine; the second threshold value is larger than or equal to the memory space required by the application to be updated after the target virtual machine is updated; the third threshold value is larger than or equal to the storage amount required by the updated application to be updated when the target virtual machine stores the updated application to be updated.

It should be noted that, in the embodiment of the present application, the preset conditions include: the unused rate of the processor in the target virtual machine is greater than or equal to a first threshold; the explanation is given by taking the case that the unused rate of the memory in the target virtual machine is greater than or equal to the second threshold value and the unused rate of the hard disk in the target virtual machine is greater than or equal to the third threshold value as examples, and details are not repeated in the following.

By way of example, assume that the first threshold is 10%, the second threshold is 20%, and the third threshold is 5%; the preset conditions include: the unused rate of the processor in the target virtual machine is greater than or equal to 10%; the unused rate of the memory in the target virtual machine is greater than or equal to 20% g and the unused rate of the hard disk in the target virtual machine is greater than or equal to 5%. When the unused rate of the processor in the target virtual machine is 40%, the unused rate of the memory in the target virtual machine is 50%, and the unused rate of the hard disk in the target virtual machine is 45%, the target virtual machine meets the preset condition.

When the target virtual machine does not satisfy the preset condition, the target virtual machine determines an update result of the application to be updated thereon as an update failure, and performs S270 described below.

When the target virtual machine satisfies the preset condition, the target virtual machine performs S230 described below.

And S230, the target virtual machine adds an update package of the application to be updated in the host machine to a file system of the target virtual machine.

And S240, the target virtual machine updates the application to be updated based on the update package of the application to be updated.

It should be noted that, the implementation of S230-S240 is similar to the implementation of S120-S130, and specific descriptions of S230-S240 may refer to the related descriptions of S120-S130, which are not repeated here.

When the above-described application to be updated fails to be updated, the following S250 to S270 are executed.

When the above-described application to be updated is successfully updated, the following S270 is executed.

S250, the target virtual machine acquires the number of times of failure in updating the application to be updated.

It should be noted that, in one process, when the update of the application to be updated fails, the target virtual machine records the number of times that the update of the application to be updated fails; when the process ends, the target virtual machine clears the number of update failures. That is, when the update of the application to be updated fails, the target virtual machine records the number of update failures of the application to be updated in the current process, and the number of update failures is cleared by the target virtual machine when the current process ends. Based on this, the implementation manner of S250 includes: the target virtual machine obtains the number of times of update failure of the application to be updated from the local.

When the number of update failures of the application to be updated is less than the preset number of failures, the target virtual machine again executes S240.

When the number of update failures of the application to be updated is greater than or equal to the preset number of failures, the target virtual machine executes S260.

And S260, the target virtual machine determines that the application to be updated fails to update, and rolls back the application to be updated to the version before updating.

It should be noted that, the implementation manner of rolling back the application to be updated to the version before updating is referred to the related art, and will not be described herein.
