[0001] The present invention relates to the field of virtualization platform systems, and in particular to a task scheduling method, system and related components of a virtualization platform system. Background Art

[0002] At present, the high availability strategy for virtual machines in the prior art mainly transfers the virtual machines on the physical node to other hosts when the physical node itself fails, so as to ensure the continuity and high availability of the tasks on the virtual machines. However, this high availability strategy does not take into account the problem of network communication failures. If there is a problem with the network communication of the physical node, even if the virtual machine on the node remains running, it cannot run the task according to the normal communication process under the premise that the communication function of the virtual machine is damaged.

[0048] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0049] The existing high-reliability strategy does not take into account the problem of network communication failure. If there is a problem with the network communication of a physical node, even if the virtual machine on the node remains running, the task cannot be performed according to the normal communication process if the communication function of the virtual machine is damaged.

[0050] This application monitors and analyzes the network connection status, and when a task node meets the migration conditions, migrates all tasks on the node to other task nodes, thereby eliminating the network communication risks of the virtual machine and ensuring the normal communication and operation of the virtual machine.

[0051] The embodiment of the present invention discloses a task scheduling method for a virtualization platform system. Figure 1 As shown, including:

[0052] S1: Monitor the network connection status of each task node; the network connection status includes the network speed and the corresponding timestamp;

[0053] It can be understood that the monitoring of the network connection status in step S1 obtains the network speed sampled continuously on each task node and the discrete timestamp corresponding to the sampling;

[0054] It can be understood that the task node here is specifically a physical server, and the network connection status of the physical server includes all network connection status of the virtual machines, virtual network cards and virtual switches set on the physical server. Assume that there are four physical servers A, B, C and D, of which A serves as the management node of the virtualization platform system, and the remaining B, C and D serve as task nodes of the virtualization platform system respectively. Different numbers of virtual machines are installed on different task nodes, and each virtual machine includes a different number of virtual network cards and virtual switches. According to the characteristics of the virtual machine, multiple physical servers can correspond to the same virtual switch, and different virtual machines can use shared storage. Further, on each task node here, the connection status may include the network connection status of the virtual machine, and / or virtual network card, and / or virtual switch. When making a subsequent judgment, the network connection status of all virtual machines, and / or virtual network cards, and / or virtual switches on a single task node can be used for network failure judgment respectively.

[0055] S2: Determine whether the network speed of each task node is lower than the preset speed and the duration exceeds the minimum fault duration. If so, it is determined that a network fault occurs at the task node;

[0056] It is understandable that under normal circumstances, a network failure is manifested in the disconnection of the network connection between the task node and the node network. At this time, the monitored network speed should be 0, but in fact, normal network communication is no longer possible when the network speed is not as low as 0. Therefore, in this embodiment, the preset speed can be selected as a value greater than 0 to more quickly and sensitively reflect the current network connection status of each task node.

[0057] Since the network connection status may be unstable or have data errors, in order to avoid misjudgment, the judgment time is required. Only when the network speed is lower than the preset speed for a period that exceeds the minimum fault duration, the task node is judged to have a network failure.

[0058] S3: According to the number and time of network failures of each task node, determine whether there is a first task node that meets the task migration condition among all task nodes;

[0059] For any task node, the task migration conditions include:

[0060] The duration of this network failure exceeds the maximum duration.

[0061] Or, multiple historical network failures satisfy the network flapping determination criteria.

[0062] It can be understood that the maximum duration can be set according to the urgency of the task requirements, for example, the maximum duration is 30s, 1min, 2min, 5min or 10min, and the urgency gradually decreases. The specific value can be set according to actual needs and is not limited here.

[0063] It is understandable that the network oscillation determination condition is generally related to the frequency of network failures, and can be specifically set according to task requirements.

[0064] Furthermore, in the determination of the task migration condition in step S3, the task migration condition can be determined based on the network failure of a single object (virtual machine, virtual network card or virtual switch) on the task node. When any object satisfies the task migration condition, the task node is the first task node. Alternatively, all network failures on the same task node can be integrated on the timeline as the network failures of the task node, and then the determination of the task migration condition in step S3 is implemented. It should be noted that the integration only concentrates the network failures of all objects on a timeline for analysis, and the network failures with overlapping timelines will not be merged. For example, the determination that the duration of the current network failure exceeds the maximum duration is usually only for a single network failure, rather than a composite network failure after the integration of two network failures overlapping on the timeline. As for the determination of whether multiple historical network failures meet the network oscillation determination condition, multiple historical network failures here also refer to the time determination of all network failures after all network failures of all objects are integrated on the same timeline.

[0065] S4: When the first task node exists, migrate all tasks on the first task node to other task nodes.

[0066] It can be understood that step S4 migrates all tasks on the first task node to other task nodes. These tasks specifically are task data or business data corresponding to virtual machines, and / or virtual network cards, and / or virtual switches. In order to ensure that the tasks on the first task node are not affected by communication and that data and business are continuous, they are transferred to other task nodes that are not the first task node.

[0067] Furthermore, in step S4, when there is a first task node, the process of migrating all tasks on the first task node to other task nodes includes:

[0068] When there is a first task node, all tasks on the first task node are migrated to other task nodes according to the task migration instruction;

[0069] The task migration instruction is specifically a direct migration instruction or a migration after shutdown instruction.

[0070] It can be understood that the task migration instructions include hot migration instructions and cold migration instructions. The hot migration instructions are direct migration instructions. When step S4 is executed, all tasks on the currently running first task node are directly migrated to other task nodes. All virtual machines using shared storage on the first task node support hot migration; the cold migration instructions are migration after shutdown instructions. When step S4 is executed, the virtual machine of the first task node is automatically and safely shut down first, and then all tasks are cold migrated to other task nodes. The virtual machines that can be automatically and safely shut down here generally refer to virtual machines with VMtools installed.

[0071] The present application discloses a task scheduling method for a virtualization platform system, including: monitoring the network connection status of each task node; the network connection status includes the network speed and the corresponding timestamp; judging whether the network speed of each task node is lower than the preset speed and the duration exceeds the minimum fault duration, if so, judging that the task node has a network fault; determining whether there is a first task node that meets the task migration condition among all the task nodes according to the number and time of the network fault occurring in each task node; when the first task node exists, migrating all tasks on the first task node to other task nodes; for any of the task nodes, the task migration condition includes: the duration of the current network fault exceeds the maximum duration, or, the network faults have met the network oscillation judgment condition for many times in history. The present application monitors and analyzes the network connection status, and when a task node meets the migration condition, all tasks on the node are migrated to other task nodes, thereby eliminating the network communication risks of the virtual machine and ensuring the normal communication and operation of the virtual machine.

[0072] The embodiment of the present invention discloses a specific task scheduling method for a virtualization platform system. Compared with the previous embodiment, this embodiment further illustrates and optimizes the technical solution. Specifically:

[0073] Regarding the analysis of whether the network failure meets the task migration condition in step S3, when judging the network oscillation judgment condition of the network failure of the task node, a time following window is generally used as the data window, the end boundary of the time following window is the current moment, and the length is a preset time period, which can be set according to demand, such as 2 hours, 30 minutes, 15 minutes, etc. As the current moment changes, the time following window moves accordingly, and the network failures corresponding to different times are exposed in the data window as the judgment basis as the action of the time following window, that is, the network failure within the preset time period up to the current moment, and there are multiple options for the judgment condition, and you can choose one to implement.

[0074] The first determination condition is: the network oscillation determination condition includes: the number of network failures occurring within a preset time period up to the current moment exceeds a first preset value.

[0075] The second determination condition is: the network oscillation determination condition includes: within the preset time period up to the current moment, the cumulative oscillation frequency of multiple historical network failures exceeds the second preset value; correspondingly, the process of determining the cumulative oscillation frequency includes: within the preset time period up to the current moment, when the interval from the occurrence time of the i-1th network failure to the occurrence time of the i-th network failure is less than the interval from the occurrence time of the i-2th network failure to the occurrence time of the i-1th network failure, the current cumulative oscillation frequency is increased by 1; i is a positive integer not less than 3 and not greater than the number of current network failures.

[0076] It can be understood that, in this determination condition, if the time interval between network failures is shortened, the current accumulated oscillation frequency is increased by one.

[0077] Further, the process of determining whether there is a first task node that meets the task migration condition among all the task nodes according to the number and time of the network failure occurring in each of the task nodes also includes:

[0078] If the number of network failures that occur to the current task node does not exceed 2 times during the preset time period up to the current moment, it is determined that the current task node does not meet the task migration condition.

[0079] It is understandable that if the network failure does not exceed 2 times within the time following window, it is insufficient to make a network oscillation determination, and the current accumulated oscillation frequency is 0, so it can be directly determined that the current task node does not meet the network oscillation determination condition.

[0080] The third determination condition is: the network oscillation determination condition includes: within the preset time period up to the current moment, the continuous oscillation frequency of multiple historical network failures exceeds the third preset value; correspondingly, the process of determining the continuous oscillation frequency includes: within the preset time period up to the current moment, when the interval from the occurrence time of the i-1th network failure to the occurrence time of the i-th network failure is less than the interval from the occurrence time of the i-2th network failure to the occurrence time of the i-1th network failure, the current continuous oscillation frequency is increased by 1; when the interval from the occurrence time of the i-1th network failure to the occurrence time of the i-th network failure is not less than the interval from the occurrence time of the i-2th network failure to the occurrence time of the i-1th network failure, the current continuous oscillation frequency is cleared; i is a positive integer not less than 3 and not greater than the number of current network failures.

[0081] It can be understood that both the third judgment condition and the second judgment condition add 1 when the time interval of the network failure is shortened. In the second judgment condition, if the time interval is suddenly not less than the time interval of the previous network failure, the cumulative oscillation frequency will not be counted, and the next time to add 1 will continue to be waited. However, in the third judgment condition, once the time interval of the network failure is no longer shortened, the continuous oscillation frequency will be reset to zero and counted again. The third judgment condition is based on the most recent continuous oscillation frequency.

[0082] In addition, the first determination condition and the second determination condition or the third determination condition may be combined together to set the network oscillation determination condition to be satisfied when the first determination condition and the second determination condition are simultaneously met, or the network oscillation determination condition to be satisfied when the first determination condition and the third determination condition are simultaneously met.

[0083] It can be understood that the first preset value, the second preset value, and the third preset value used for determination here can be set according to the length of the preset time period, the reliability requirements of the platform system, etc., and are not limited here.

[0084] Correspondingly, the present application also discloses a task scheduling system for a virtualization platform system, see Figure 2 As shown, including:

[0085] Status monitoring module 1, used to monitor the network connection status of each task node; the network connection status includes network speed and corresponding timestamp;

[0086] Fault determination module 2, used to determine whether the network speed of each task node is lower than a preset speed and the duration exceeds the minimum fault duration, and if so, determine that a network fault occurs at the task node;

[0087] A node determination module 3 is used to determine whether there is a first task node that meets the task migration condition among all the task nodes according to the number and time of the network failure occurring in each of the task nodes;

[0088] The task migration module 4 is used for migrating all tasks on the first task node to other task nodes when the first task node exists;

[0089] For any of the task nodes, the task migration conditions include:

[0090] The duration of the network failure exceeds the maximum duration.

[0091] Or, the network failure has occurred multiple times in history and meets the network flapping determination condition.

[0104] In the preset time period up to the current moment, when the interval from the time when the i-1th network failure occurs to the time when the i-th network failure occurs is less than the interval from the time when the i-2th network failure occurs to the time when the i-1th network failure occurs, the current continuous oscillation frequency is increased by 1;

[0105] When the interval between the occurrence time of the (i-1)th network failure and the occurrence time of the (i)th network failure is not less than the interval between the occurrence time of the (i-2)th network failure and the occurrence time of the (i-1)th network failure, the current continuous oscillation frequency is cleared;

[0106] i is a positive integer not less than 3 and not greater than the number of the current network failures.
