Detailed Description
The present application will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present application more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the application.
In one embodiment, as shown in fig. 1, a virtual machine enhancement tool upgrading method is provided, and the method is applied to a virtual machine for illustration in this embodiment. In this embodiment, the method includes the steps of:
step 102, responding to the virtual machine enhancement tool upgrading request, and acquiring the type of the operating system.
The virtual machine enhancement Tools (VM Tools) are self-contained in the virtual machine, and are used for enhancing the performance of the virtual graphics card and the hard disk, and synchronizing the virtual machine with a host file, a clock or a network driver. For convenience of description, the virtual machine enhancement tool may be simply referred to as an enhancement tool hereinafter. A virtual machine is a complete computer system that runs in a completely isolated environment with complete hardware system functionality emulated by software. The virtual machine enhancement tool upgrade request is used for instructing the virtual machine to upgrade the virtual machine enhancement tool. Various operating systems, such as windows systems and various versions of linux systems, may be running in the virtual machine.
Specifically, the virtual machine obtains a virtual machine enhancement tool upgrade request, and in response to the virtual machine enhancement tool upgrade request, obtains a type of an operating system running in the virtual machine. The upgrade modes of the virtual machine enhancement tools corresponding to different operating systems are different.
Before upgrading the virtual machine enhancement tool, the virtual machine can bind the image file, call the qga mount method to display the disk character, and then judge whether the image file is successfully bound. If the binding is successful, an enhanced tool upgrade operation may be performed. If the binding fails, the upgrade operation cannot be performed.
And 104, calling a corresponding upgrade service according to the type of the operating system, and reading the new version of the enhancement tool file from the upgrade image file of the virtual machine.
And step 106, upgrading the virtual machine enhancement tool according to the enhancement tool file of the new version through the upgrade service.
The upgrade service refers to a program for upgrading the virtual machine enhancement tool, and the program is automatically completed by the system and does not need to interact with a user. The new version of the enhancement tool file refers to the latest file of the virtual machine enhancement tool.
The upgrade modes of the virtual machine enhancement tools corresponding to different operating systems are different, but the problem that the child process terminates the parent process exists, so that upgrade operation is required to be performed by adding upgrade services corresponding to the operating systems.
When different operating systems are operated in the virtual machine, the operating system can acquire the current version number, call upgrading service corresponding to the operating system and copy and replace related files of the virtual machine enhancement tool. Specifically, the new version of the enhancement tool file is read from the upgrade image file of the virtual machine through the upgrade service. And replacing the enhancement tool file of the old version with the enhancement tool file of the new version to finish the upgrading operation of the enhancement tool of the virtual machine. The copied and replaced enhancement tool files may include executable files to be updated, such as executable files of the enhancement tool, dependency files running the enhancement tool, and the like.
Optionally, the upgrading process of each virtual machine is not affected, and when a plurality of virtual machines receive the upgrading request of the machine-simulated enhancement tool at the same time, upgrading operation can be performed at the same time, so that a batch upgrading function is realized.
According to the virtual machine enhancement tool upgrading method, after the virtual machine obtains the virtual machine enhancement tool upgrading request, the virtual machine can automatically respond to the request, corresponding upgrading service is called according to the type of the operating system, the enhancement tool file of the new version is read from the upgrading image file, and the virtual machine enhancement tool is upgraded according to the enhancement tool file of the new version. Automatic upgrading is supported, manual operation is not needed, and the upgrading efficiency of the virtual machine enhancement tool is improved.
In one embodiment, as shown in fig. 2, invoking the upgrade service corresponding to the operating system type, and reading the new version of the enhancement tool file from the upgrade image file of the virtual machine includes:
step 202, when the operating system type is the first operating system, calling an asynchronous service, stopping the virtual machine enhancement tool, and reading the enhancement tool file of the new version from the upgrade image file of the virtual machine.
And 204, when the type of the operating system is the second operating system, calling a monitoring service, stopping the virtual machine enhancement tool, and reading the enhancement tool file of the new version from the upgrade image file of the virtual machine.
Wherein the first operating system is different from the second operating system. For example, the first operating system may be linux. The second operating system may be windows. Asynchronous service (asynchronous application) refers to the step of plugging a call into a system thread pool and entrusting a system process to call so as to realize the function of starting and stopping a virtual machine enhancement tool. The monitoring service is a self-developed windows service, and operates independently without being influenced by the enhancement tool.
Specifically, aiming at the linux operating system, the linux operating system is called to perform upgrading operation through asynchronous service. Further, in the upgrading process of the linux operating system, the virtual machine enhancement tool is stopped first, and then a new version of enhancement tool file is read from an upgrading image file of the virtual machine.
The upgrade process of windows operating system relies on the newly added listening service. The monitoring service is registered in a windows service list when the virtual machine enhancement tool is installed, and the monitoring service is started automatically and continuously operates. The windows operating system can perform upgrading operation through the monitoring service. Further, during the operation process of the monitoring service, the virtual machine enhancement tool is stopped first, and then the enhancement tool file of the new version is read from the upgrade image file of the virtual machine.
In this embodiment, for different operating systems, the enhancement tool is automatically upgraded by different upgrade services, so that the upgrade efficiency and upgrade accuracy of the enhancement tool can be greatly improved.
In an alternative to the above embodiment, invoking an asynchronous service, stopping a virtual machine enhancement tool, and reading a new version of the enhancement tool file from the upgrade image file, includes: calling asynchronous service and pushing the upgrade program into a first operating system; and executing the upgrading program through the first operating system, stopping the virtual machine enhancement tool, and reading the enhancement tool file of the new version from the upgrading image file.
Wherein the upgrade program is a separate process for performing the upgrade operation.
Specifically, the first operating system may send a virtual machine enhancement tool upgrade request to an asynchronous service that, upon receiving the upgrade request, pushes the upgrade program into a thread pool of the first operating system. And executing the upgrade program through the thread pool, and stopping the virtual machine enhancement tool after the upgrade program starts to run. And then, reading the new version of the enhancement tool file from the upgrade image file. By asynchronously calling the upgrade program, the upgrade program can be immediately pushed into the thread pool for upgrade operation after an upgrade request is acquired, and the asynchronous service can continuously acquire the upgrade request, so that the occupation of system resources can be reduced.
In this alternative manner, the first operating system upgrades the enhancement tool by asynchronously calling the upgrade program, which can save system resources.
In the above alternative, upgrading, by the upgrade service, the virtual machine enhancement tool according to the enhancement tool file of the new version includes: after the first operating system acquires the new version of the enhancement tool file, replacing the old version of the enhancement tool file according to the new version of the enhancement tool file; starting the virtual machine enhancement tool to finish the upgrading of the virtual machine enhancement tool.
And executing an upgrade program by a thread pool of the first operating system, stopping the virtual machine enhancement tool after the upgrade program starts to run, and reading the enhancement tool file of the new version from the upgrade image file. The new version of the enhancement tool file is the complete enhancement tool file. And then, replacing the enhancement tool file of the old version with the enhancement tool file of the new version, so that the enhancement tool can be completely and accurately upgraded. And then starting the virtual machine enhancement tool, comparing the updated version number of the virtual machine enhancement tool with the current version number acquired before upgrading, if the version numbers are inconsistent, indicating that the version number of the virtual machine enhancement tool is updated, and finishing upgrading of the virtual machine enhancement tool.
In the optional mode, after the first operating system acquires the new version of the enhancement tool file, the first operating system can automatically replace the old version of the enhancement tool file according to the new version of the enhancement tool file and start the virtual machine enhancement tool, the whole upgrading process does not need to restart the virtual machine, and the whole upgrading process is silent and rapid, so that the noninductive upgrading is realized. In addition, the copy and replacement of the enhancement tool files are directly carried out, so that the problem that partial drivers remain and the network or hard disk function is abnormal due to incomplete unloading of the enhancement tools caused by manual upgrading can be avoided, and the accurate upgrading of the enhancement tools is realized.
In an alternative manner of the above embodiment, upgrading, by the upgrade service, the virtual machine enhancement tool according to the enhancement tool file of the new version includes: replacing the enhancement tool file of the old version according to the enhancement tool file of the new version by monitoring service; starting the virtual machine enhancement tool to finish the upgrading of the virtual machine enhancement tool.
And a monitoring service is operated in the second operating system, an upgrading program is executed through the monitoring service, the virtual machine enhancement tool is stopped, and a new version enhancement tool file is read from the upgrading image file of the virtual machine. The new version of the enhancement tool file is the complete enhancement tool file. And then, replacing the enhancement tool file of the old version according to the enhancement tool file of the new version, so that the enhancement tool can be completely and accurately upgraded. And further starting the virtual machine enhancement tool, judging whether the version number of the virtual machine enhancement tool is updated, and if so, finishing the upgrading of the virtual machine enhancement tool.
In the optional mode, the second operating system automatically replaces the enhancement tool file of the old version according to the enhancement tool file of the new version through monitoring service, and starts the virtual machine enhancement tool, the whole upgrading process does not need to restart the virtual machine, and the whole upgrading process is silent and rapid, so that the noninductive upgrading is realized. In addition, the copy and replacement of the enhancement tool files are directly carried out, so that the problem that partial drivers remain and the network or hard disk function is abnormal due to incomplete unloading of the enhancement tools caused by manual upgrading can be avoided, and the accurate upgrading of the enhancement tools is realized.
In one embodiment, the method further comprises: when the type of the operating system is the second operating system, sending a virtual machine enhancement tool upgrading request to the virtual machine enhancement tool; the virtual machine enhancement tool upgrading request is used for indicating the virtual machine enhancement tool to modify the content of the pre-built shared memory; when the monitoring service monitors that the content of the shared memory is changed, stopping the virtual machine enhancement tool, and reading the enhancement tool file of the new version from the upgrade image file of the virtual machine.
The shared memory refers to a memory space shared among processes, and may also be referred to as a shared memory space.
The virtual machine enhancement tool communicates with the listening service by sharing memory. Specifically, the monitoring service opens up a shared memory space, names the shared memory space, and then binds the shared memory space to the manager account. By binding the shared memory space to the manager account. Because the virtual machine enhancement tool uses a plurality of operations requiring the administrator related rights, such as high-level rights operation, the shared memory space is bound to the management user to ensure that the operations requiring the high-level rights can normally run.
After the virtual machine acquires the upgrade request of the virtual machine enhancement tool, the virtual machine sends the upgrade request to the virtual machine enhancement tool. The virtual machine enhancement tool modifies the contents of the shared memory space according to the upgrade request. The monitoring service monitors the shared memory space in real time, when the content of the shared memory space is monitored to be changed, the monitoring service indicates that the enhancement tool needs to be updated, the monitoring service starts to execute an updating program, stops the virtual machine enhancement tool, reads a new version of enhancement tool file from an updating image file of the virtual machine, replaces an old version of enhancement tool file according to the new version of enhancement tool file, and then starts the virtual machine enhancement tool to complete the updating of the virtual machine enhancement tool.
In this embodiment, by constructing a shared memory space between the virtual machine enhancement tool and the monitoring service, when the monitoring service monitors that the content of the shared memory space is changed, it indicates that the virtual machine enhancement tool needs to be upgraded, so that the upgrade operation of the virtual machine enhancement tool is rapidly executed, and silence rapid upgrade is achieved.
In one embodiment, the upgrade operations of the first operating system and the second operating system are implemented by executing an upgrade program, and after the first operating system and the second operating system read the new version of the enhancement tool file, the first operating system and the second operating system execute operations such as exception processing and compatibility processing. Specifically, the exception refers to unsuccessful performance of the upgrade program in the process of performing the upgrade, such as failure of replacing the file, failure of the dependent package to cause service start-up, and the like. If the upgrade program is abnormal, code rollback is performed, so that the enhancement tool of the old version can be ensured to normally operate. For compatible processing, the upgrade program can judge whether the new version of the enhancement tool file is compatible with the environment in which the old version of the enhancement tool file operates in the operation process, if not, the enhancement tool is not upgradeable, and the file replacement process is not performed, so that the upgrade process is blocked. By executing operations such as exception handling and compatible handling, the exception of the upgrade operation of the enhancement tool can be found in time, and the exception condition can be handled quickly.
In one embodiment, as shown in fig. 3, a flow chart of a virtual machine enhancement tool upgrade process of the first operating system is shown, where the upgrade request refers to a virtual machine enhancement tool upgrade request, and the asynchronous service module refers to an asynchronous service. The method comprises the steps that a virtual machine calls an interface monitoring module (api monitoring module), an upgrading request is accessed, the upgrading request is sent to an asynchronous service module through a virtual machine enhancement tool, and after the upgrading request is received, the asynchronous service module pushes an upgrading program into a first operating system, and upgrading operation is executed through the first operating system.
In one embodiment, as shown in fig. 4, a flow chart of a virtual machine enhancement tool upgrade process of the second operating system is shown, where the upgrade request refers to a virtual machine enhancement tool upgrade request. By executing the monitoring service installation program, the installation of the virtual machine enhancement tool is realized. The virtual machine calls an interface monitoring module (api monitoring module), accesses the upgrade request, sends the upgrade request to the virtual machine enhancement tool, and the virtual machine enhancement tool informs the monitoring service to upgrade through the upgrade communication module. The content of the shared memory can be modified by upgrading the communication module. When the monitoring service monitors that the content of the shared memory is changed, namely, the request in the shared memory is acquired, the upgrading operation is executed.
In another embodiment, as shown in fig. 5, there is provided a virtual machine enhancement tool upgrade method, which includes the steps of:
step 502, in response to a virtual machine enhancement tool upgrade request, obtains an operating system type. When the operating system type is the first operating system, executing step 504; when the operating system type is the second operating system, step 506 is performed.
Step 504, calling asynchronous service, pushing the upgrade program into the first operating system; and executing the upgrading program through the first operating system, stopping the virtual machine enhancement tool, and reading the enhancement tool file of the new version from the upgrading image file of the virtual machine. Execution continues with step 508.
Step 506, sending the virtual machine enhancement tool upgrade request to the virtual machine enhancement tool; when the monitoring service monitors that the content of the shared memory is changed, stopping the virtual machine enhancement tool, and reading the enhancement tool file of the new version from the upgrade image file of the virtual machine enhancement tool. Execution continues with step 510.
Step 508, replacing the old version of the enhancement tool file with the new version of the enhancement tool file. Execution continues with step 512.
Step 510, replacing the old version of the enhancement tool file according to the new version of the enhancement tool file by the listening service.
Step 512, starting the virtual machine enhancement tool to complete the upgrade of the virtual machine enhancement tool.
In this embodiment, after the virtual machine obtains the upgrade request of the virtual machine enhancement tool, the virtual machine can automatically respond to the request, call the corresponding upgrade service according to the type of the operating system, read the enhancement tool file of the new version from the upgrade image file, and upgrade the virtual machine enhancement tool according to the enhancement tool file of the new version. Automatic upgrading is supported, manual operation is not needed, and the upgrading efficiency of the virtual machine enhancement tool is improved.
