And in the cloud computing scheme, the running process on the physical machine is protected, so that the important service process can still survive under the condition of insufficient resources. When the cloud computing scheme relates to the virtual machine, the cloud computing cannot perform protection setting for the process in the virtual machine due to the permission problem, and when the memory resources of the virtual machine are tense, the important process may be terminated.
In order to perform protection setting on a process in a virtual machine, some related technologies need to log into the virtual machine to perform setting, which makes high demands on operators in technical expertise. Moreover, the virtual machine is dynamic relative to the physical machine, and is frequently opened and destroyed, and the virtual machine may need to perform protection setting on the process therein after each opening. The method needs to frequently log in the virtual machine and operate one by one aiming at a plurality of processes in the virtual machine, and the operation method is complex and tedious, large in workload and low in execution efficiency, and greatly influences user experience.
Aiming at the problems, the embodiment of the specification aims to provide a process management method for a virtual machine, provide a special function interface to receive a process protection command, avoid a user to log in the virtual machine to operate, and reduce the operation complexity of the user; and scoring the processes in the virtual machine according to the process protection command, and determining the sequence of process termination when resources are tensed by taking the scoring as a basis so as to protect the important processes.
In view of the above object, in one aspect, an embodiment of the present disclosure provides a virtual machine process management method.
As shown in FIG. 1, one or more alternative embodiments of the present description provide a virtual machine process management method. The method is applied to a virtualization management platform, and comprises the following steps:
s1: and the virtualization management platform receives a process protection command and forwards the process protection command to a target virtual machine based on rule information in the process protection command.
In the virtualization platform, a special function interface API may be provided to receive the program protection command. The process protection command may include rule information and the process level. The virtual machine information in the rule information is used for designating a target virtual machine, and the process information in the rule information is used for designating a target process in the target virtual machine. The process level can be flexibly set according to the importance degree of the target process and the actual demands of users.
The virtual machine information may be identity information of the target virtual machine, and the corresponding process information may be identity information of the target process.
The process protection command can be forwarded to a HOST corresponding to the target virtual machine by analyzing the rule information in the process protection command, and then the HOST forwards the process protection command to the target virtual machine.
S2: and calculating the process score of the target process corresponding to the process protection command in the target virtual machine based on a preset score calculation rule.
And in the target virtual machine, according to a preset scoring calculation rule, determining the corresponding process score of the target process according to the process grade calculation in the process protection command. The process grade is set according to the importance degree of the target process and the actual demands of the users, the importance degrees of different processes and the actual demands of the corresponding users are different, and the corresponding process scores determined according to the score calculation rules are different. Thus, the different process scores may reflect the difference in importance of the different processes and the actual needs of the user.
Corresponding process grades are set for the target process in the process protection command, and for a plurality of virtual machines in the virtualized platform, the plurality of processes in each virtual machine have corresponding process grades, and the corresponding process scores of the processes can be calculated and determined correspondingly. In some alternative embodiments, for processes that do not receive the corresponding process protection command, the process level may be selected as a default value.
S3: and sequencing the processes in the target virtual machine according to the process scores, and when the processes need to be terminated to release memory resources, preferentially terminating the processes with the front sequencing.
After determining the process scores of the plurality of the integrated processes, the processes in the target virtual machine can be ranked according to the process scores to generate a process sequence, so that the sequence of the processes in the process sequence is different.
When the memory resources of the target virtual machine cannot meet the requirement that a plurality of processes run simultaneously, part of the processes need to be terminated to release the memory resources, and the sequence of terminating the processes is determined according to the sequencing results of the processes. The top-ranked process may be preferentially terminated while the bottom-ranked process is kept running, in such a way that the bottom-ranked process may be protected.
In some alternative embodiments, when the plurality of processes in the target virtual machine are ranked according to the process score, the plurality of processes in the target virtual machine may be ranked from large to small by the process score. And when the process needs to be terminated, starting to execute termination operation from the first process of the sequencing result, and stopping the memory resource of the target virtual machine to meet the running requirement.
The process scores serving as sequencing basis are calculated and generated according to the process grades in the process protection command. Therefore, by adjusting the process level of the target process, the sequence of the target process in the process sequence can be changed, so that the sequence of the target process termination is affected. In the process protection command, setting the corresponding process level for the target process can affect the termination sequence of the final target process. By the method, the terminating sequence of the target process with high importance or meeting the specific requirements of the user can be guaranteed to be close to the back, so that the survival rate of the target process is improved, and the protection setting for the target process is realized.
As shown in fig. 2, in a method for managing a process of monitoring a virtual machine according to one or more alternative embodiments of the present application, forwarding the process protection command to a target virtual machine based on rule information in the process protection command includes:
s201: and sending the process protection command to a message queue service.
The process protection command may be sent to the message queue service via a remote invocation protocol.
In some alternative embodiments, the message queue service establishes a plurality of message queues named by host names according to registered hosts, wherein the plurality of message queues respectively correspond to the plurality of hosts.
After receiving the process protection command, the message queue service determines a target host corresponding to the virtual machine message in the process protection command by analyzing the rule information in the process protection command. Further, the message queue service sends the process protection command to the message queue corresponding to the target host for storage.
S202: and monitoring the message queue service by a target host corresponding to the target virtual machine, and acquiring the process protection command from the message queue service.
The target host may obtain the process protection command from the message queue service by listening.
In some alternative embodiments, the process protection command may be obtained by the computer-service in the target host listening for the message queue corresponding to the target host in the message queue service.
S203: and the target host machine performs attribution verification on the process protection command according to the rule information, and sends the process protection command to the target virtual machine after verification is passed.
And the target host machine can carry out attribution verification according to the virtual machine information in the process protection command so as to determine whether the host machine contains the target virtual machine appointed by the virtual machine information. After determining that the target virtual machine belongs to the target host, the target host may further send the process protection command to the target virtual machine.
Referring to fig. 3, a schematic diagram of a communication architecture of the virtualization platform according to an embodiment of the present disclosure is shown. In some alternative embodiments, after the computer-service in the target host monitors the process protection command from the message queue service, a home check may be performed for the process protection command. After determining that the target virtual machine belongs to the target host, the computer-service can further verify whether the operating system of the target virtual machine belongs to a supported operating system type, and after the operating system type is also verified to be in compliance with the condition, the computer-service forwards the process protection command to the target virtual machine.
When forwarding the process protection command, the computer-service may first send the process protection command to the agent-service. And establishing connection with the agent service in the target virtual machine by the agent-service, and then sending the process protection command to the agent service. In the target virtual machine, the agent service may further verify whether the target process corresponding to the process information in the process protection command belongs to the target virtual machine.
As shown in fig. 4, in a virtual machine process management method provided in one or more alternative embodiments of the present specification, the process protection command includes a process level of the target process,
based on a preset scoring calculation rule, calculating a process score of a target process corresponding to the process protection command in the target virtual machine, including:
s401: determining that the process score of the target process takes a minimum value S in response to the process level being advanced min 。
S402: determining that the process score of the target process takes a maximum value S in response to the process level being low max 。
S403: and determining the process score according to the running memory of the target process and the total memory of the target virtual machine in response to the process grade being the intermediate grade.
The target process may be scored according to its running memory duty cycle in the target virtual machine. The running memory duty ratio may be determined by calculating a running memory of the target process and a total memory of the target virtual machine.
In some optional embodiments, when determining the process score according to the running memory of the target process and the total memory of the target virtual machine, the process score is:
Score＝S min +min(max(β，S max -(S max *Mem)/Mec)，S max -1)
wherein Score represents the progress Score, S min ，S max Representing the minimum and maximum values of the progress scores, respectively, beta (S min ＜β＜S max ) For intermediate parameters, mem represents the running memory of the target process, and Mec represents the total memory of the target virtual machine.
Minimum value S of the process score min And maximum S max Can be set to-1000/1000, respectively, and the intermediate parameter beta can be set to 2. The process scores are as follows:
Score＝-1000+min(max(2，1000-(1000*Mem)/Mec)，999)
taking the process grade of the process A as a middle grade, and taking the total memory 8G of the target virtual machine and the running memory 3G of the process A as examples, calculating the process score of the target process as-375; the process level of the process B is a middle level, and the total memory 8G of the target virtual machine and the running memory 5G of the process B are exemplified, and the corresponding process score is-625. When the process A with the process score of-375 is ranked forward according to the process score from large to small, when the target virtual machine resources are tense, part of the processes in the virtual machine need to be terminated to relieve the resource pressure, the process A ranked forward is easier to be terminated, and compared with the process B with the process score of-625, the process B has higher survival rate compared with the process A. Such a way achieves process protection for process B.
In the virtual machine process management method, the process score corresponding to a target process with a high process grade is set to be the minimum value, and when the target virtual machine resources are tense, the target process is positioned at the last of a process sequence, and the process survival rate is highest; and setting the process score corresponding to the target process with the low process level as the maximum value, and when the resources of the target virtual machine are tense, the target process is positioned at the forefront of the process sequence and is terminated first. For the target process with the intermediate process grade, the process score is determined according to the operating memory ratio, the higher the operating memory ratio is, the higher the protection degree is when resources are tensed, and the higher the corresponding process survival rate is after the positions in the process sequence are located. The method is equivalent to giving different process survival rates to a plurality of processes in the target virtual machine according to the process level and the running memory ratio, so that process protection setting can be realized for the plurality of processes in the target virtual machine.
The process level in the process protection command may be set directly by a user, and may also be determined according to the dynamic priority of the corresponding target process.
In one or more embodiments of the present disclosure, a method for determining a process level of a virtual machine includes: setting the process level according to the dynamic priority of the target process;
the setting the process level according to the dynamic priority of the target process includes:
setting the process level to a high or medium level in response to the dynamic priority being highest;
setting the process level to a medium or low level in response to the dynamic priority being lowest;
and setting a process level according to the importance of the target process in response to the dynamic priority being between the highest and lowest.
In determining the process level of the target process, reference is made to the dynamic priority of the target process. The dynamic priority may be represented by a priority value: and when the dynamic priority is highest, the priority value takes the maximum value, and when the dynamic priority is lowest, the priority value takes the minimum value.
For the case where the dynamic priority is highest, the process level corresponding to the target process may be set to high or medium level, but not to low level. The purpose of this arrangement is to avoid that the target process with the highest dynamic priority is terminated preferentially when the memory resources are strained due to the process level being set to a low level. Accordingly, for the case where the dynamic priority is lowest, the process level corresponding to the target process may be set to a medium level or a low level, but not to a high level. The purpose of this arrangement is to avoid that the target process with the lowest dynamic priority has a high survival rate due to the process level being set to be high, which has an influence on the survival rate of other processes with high priorities.
For the target process with the highest and lowest dynamic priority, the target process is set according to the importance of the target process, and the corresponding process level can be set to be high-level, medium-level or low-level. Typically, the process level of the target process having a dynamic priority between the highest and lowest is set to a medium level.
It should be noted that the method of the embodiments of the present disclosure may be performed by a single device, such as a computer or a server. The method of the embodiment can also be applied to a distributed scene, and is completed by mutually matching a plurality of devices. In the case of such a distributed scenario, one of the devices may perform only one or more steps of the methods of embodiments of the present disclosure, the devices interacting with each other to accomplish the methods.
It should be noted that the foregoing describes some embodiments of the present disclosure. Other embodiments are within the scope of the following claims. In some cases, the actions or steps recited in the claims may be performed in a different order than in the embodiments described above and still achieve desirable results.
