The present application relates to the technical field of cloud computing, and in particular to a virtual machine migration method, electronic equipment and storage media.

At present, for the management of cloud platforms, a system of monitoring physical nodes is usually used, requiring operation and maintenance personnel to manage the operation and management of the overall service. When a physical node is abnormal or requires maintenance, the services running on this physical node are transferred to other physical nodes, and the behavior of service transfer is usually manually operated by operation and maintenance personnel. For the response to emergencies, manual operations usually have a certain time delay, which affects the efficiency of operation and maintenance.

Take the Openstack cloud platform as an example. When a computing node is abnormal and causes the computing node to shut down or restart, or when a computing node fails to affect the normal operation of the Openstack cloud platform, the virtual machine of the computing node needs to be migrated to other idle computing nodes. When the operation and maintenance personnel find that the Openstack cloud platform is abnormal, they can judge whether to migrate the virtual machine (Virtual Machine, VM) based on the monitoring data, and use the evacuate command in the Openstack Nova module to migrate the virtual machine to other computing nodes. Using this command to migrate a virtual machine requires the operation and maintenance personnel to manually input the command or call the application programming interface (Application Programming Interface, API), which will cause a certain time delay. When exceptions are encountered, additional time is required to restore virtual machines.

The present application provides a virtual machine migration method, an electronic device and a storage medium, so as to improve the migration efficiency of the virtual machine.

Determines whether a compute node satisfies a trigger condition. Wherein, the trigger condition includes that the offline time of the computing node reaches a preset time, or the status of the computing node is unstable. If the computing node meets the trigger condition, it sends a message to the control node to migrate the virtual machine.

In one embodiment, the computing node goes offline, including: the nova-compute proxy service goes offline, the number of nova-compute proxy services in the offline state is 1, the 10G network goes offline and the 1G network goes offline.

In another embodiment, the state of the computing node is unstable, including: the nova-compute proxy service is offline, the number of nova-compute proxy services in the offline state is 1, and the 10G network is offline and in the offline state The number of computing nodes in the 10G network is 1.

In another embodiment, when the number of nova-compute proxy services in the offline state is 1, and the frequency of nova-compute proxy service offline reaches the first preset frequency, and in the 10G network in the offline state The number of computing nodes is 1, and the frequency of 10G network disconnection reaches the second preset frequency, and it is determined that the status of the computing nodes is unstable.

In another embodiment, the virtual machine migration method further includes: calculating and displaying the migration time of the virtual machine.

Feedback the news of virtual machine migration to the monitoring node. Check whether the state of the virtual machine is consistent with that before migration. If the state of the virtual machine is inconsistent with that before the migration, the virtual machine is repaired.

In one of the implementation manners, checking the status of the cloud platform management system includes: checking whether there are idle computing nodes. Check whether the status of the nova service is normal. Check whether the status of the power supply is normal.

The electronic device in another embodiment of the present application includes a communication module, a display screen, a memory, and a processor. The processor runs computer programs or codes stored in the memory to implement the above-mentioned virtual machine migration method in the embodiment of the present application.

The storage medium in another embodiment of the present application is used to store computer programs or codes. When the computer programs or codes are executed by the processor, the above-mentioned virtual machine migration method in the embodiment of the present application is realized.

In the embodiment of this application, monitoring nodes and triggering conditions are set in the cloud platform management system. When the monitoring data meets the triggering conditions, the system will automatically start the migration of the virtual machine, which can automatically migrate the virtual machine away from the faulty node, resume online, and process the virtual machine in time.

In the embodiment of the present application, the physical nodes include a monitor node (Monitor Node) 110 , a control node (Control Node) 120 and a computing node (Compute Node) 130 . A physical node can be an electronic device, such as a smart phone, a tablet computer, a personal computer (Personal Computer, PC), a personal digital assistant (Personal Digital Assistant, PDA), a router, a workstation, or a server.

FIG. 1 is a schematic structural diagram of a cloud platform management system 100 according to an embodiment of the present application.

Referring to FIG. 1 , the cloud platform management system 100 includes a monitoring node 110 , a control node 120 and a computing node 130 . Wherein, the monitoring node 110 is communicatively connected to the computing node 130 and the control node 120 , and the control node 120 is communicatively connected to the computing node 130 .

In this embodiment, the communication connection includes wired connection and wireless connection. Wherein, wired connection refers to connection through a wired transmission medium (such as optical fiber or twisted pair). Wireless connection refers to connection through wireless transmission media (such as WiFi, Bluetooth, NFC, or wireless communication networks such as 2G/3G/4G/5G).

Computing nodes 130 are used to run one or more virtual machines.

The control node 120 is used to control one or more computing nodes 130 , and migrate the virtual machine of one computing node 130 to another computing node 130 .

The monitoring node 110 is used for monitoring the status of the computing node 130 to determine whether the computing node 130 is abnormal. When the computing node 130 is abnormal, the monitoring node 110 sends a message to the control node 120 to migrate the virtual machine of the abnormal computing node 130 to other available computing nodes 130 .

In this embodiment, the monitoring node 110 can determine whether the computing node 130 is abnormal by setting a certain trigger condition. When the status of the computing node 130 satisfies the trigger condition, the monitoring node 110 determines that the computing node 130 is abnormal, and sends a message to the control node 120 to migrate the virtual machine. When the status of the computing node 130 does not meet the trigger condition, the monitoring node 110 determines that the computing node 130 is normal, and continues to monitor the status of the computing node 130 .

In one of the implementation manners, the trigger condition includes that the offline duration of the computing node 130 reaches a preset duration, or the status of the computing node 130 is unstable. Wherein, the value range of the preset duration is 1min-5min. For example, the preset time may be 2 minutes.

The disconnection of the computing node 130 includes the following four conditions: the nova-compute proxy service is disconnected, the number of nova-compute proxy services in the disconnected state is 1, the 10G network is disconnected and the 1G network is disconnected. Wherein, the 10G network refers to the network between the control node 120 and the computing node 130, and the virtual machine is migrated on the 10G network. The 1G network refers to the network between the monitoring node 110 and the computing node 130, and monitoring signals are transmitted on the 1G network. The nova-compute proxy service can provide an entry point for managing and configuring virtual machines. The nova-compute agent service runs on the computing node 130 and is responsible for managing instances on the computing node 130 . When the above four conditions are met simultaneously, it may be determined that the computing node 130 is offline.

The unstable state of computing node 130 includes the following four conditions: the nova-compute proxy service is offline, the number of nova-compute proxy services in the offline state is 1, the 10G network is offline and the 10G network is in the offline state The number of computing nodes 130 is one. When the number of nova-compute proxy services in the offline state is 1, and the frequency of nova-compute proxy service offline reaches the first preset frequency, and the number of computing nodes 130 in the 10G network in the offline state is 1 , and when the frequency of 10G network disconnection reaches the second preset frequency, it can be determined that the state of the computing node 130 is unstable. Among them, the first A value range of the preset frequency is 8/10min-14/10min. For example, the first preset frequency may be 14/10 minutes. The value range of the second preset frequency is 4/10min-7/10min. For example, the second preset frequency may be 7/10 minutes.

Specifically, in the 10G network, the nova-compute proxy service sends a data packet every 30 seconds to manage instances on the computing nodes 130 during normal operation. In a period of 10 minutes, the nova-compute proxy service can send 20 data packets in total. When the packet loss rate of sending packets reaches 40%-70%, that is, when the first preset frequency is 8/10min-14/10min, it can be determined that the status of the nova-compute proxy service is unstable. The computing node 130 sends a data packet every 60 seconds during normal operation to reduce the interference of the broadcast storm. In a period of 10 minutes, the computing node 130 can send 10 data packets accumulatively. When the packet loss rate of sending packets reaches 40%-70%, that is, when the second preset frequency is 4/10min-7/10min, it can be determined that the state of the computing node 130 is unstable. When it is determined that the nova-compute agent service and the working status of the computing node 130 are both unstable, the monitoring node 110 determines that the computing node 130 is abnormal, and sends a message to the control node 120 to migrate the virtual machine.

In one of the implementation manners, when the monitoring node 110 determines that multiple computing nodes 130 are abnormal, the virtual machines on each computing node 130 where the abnormality occurs are migrated sequentially, so as to reduce the need to migrate the virtual machines on one abnormal computing node 130 to another The status of an abnormal computing node 130 .

For example, when the monitoring node 110 determines that the first computing node 130 and the second computing node 130 are abnormal, the monitoring node 110 sends a first message to the control node 120 to migrate the virtual machine on the first computing node 130 . After the migration of the virtual machine on the first computing node 130 is completed, the monitoring node 110 sends a second message to the control node 120 to migrate the virtual machine on the second computing node 130 .

In one of the implementation manners, the monitoring node 110 can switch to the safe state to stop migrating virtual machines on other computing nodes 130 .

Specifically, when the monitoring node 110 determines that a plurality of computing nodes 130 are abnormal, it sends a message to the control node 120 to migrate the virtual machine. The control node 120 searches for an idle computing node 130. Migrate the virtual machines on each computing node 130 where the exception occurs in sequence. When the control node 120 starts to migrate a virtual machine on an abnormal computing node 130 , the monitoring node 110 switches to the insurance state, and stops migrating virtual machines on other abnormal computing nodes 130 . When it is determined that the migration of the virtual machine on an abnormal computing node 130 is completed, the monitoring node 110 switches back to the working state to continue monitoring the status of the computing node 130 .

In one of the implementation manners, when the monitoring node 110 sends a message to the control node 120, the monitoring node 110 checks the thread flag and state lock of the control node 120 to reduce re-entry ) status. Wherein, the thread flag is used to indicate whether the control node 120 is running the migration program of the virtual machine. The state lock is used to indicate whether the control node 120 is in a locked state.

For example, when the thread flag flag=1, it means that the control node 120 is running the migration program of the virtual machine, and the control node 120 feeds back status information to the monitoring node 110 to stop the new migration program and wait for the current migration program to run complete. When the thread flag flag=0, it means that the control node 120 is in an idle state, and the control node 120 feeds back status information to the monitoring node 110 to start the migration program. When the state lock=1, it means that the control node 120 is in the locked state, and at this time the control node 120 stops working and will not respond to the message from the monitoring node 110 . When the state lock=0, it means that the control node 120 is in an unlocked state, and at this time the control node 120 restarts to work and feeds back state information to the monitoring node 110 .

In one of the implementation manners, when the control node 120 migrates the virtual machine, it checks the status of the cloud platform management system 100 .

Specifically, the control node 120 checks whether there is an idle computing node 130 , checks the status of the nova service and the power supply, and records the status of the virtual machine on the abnormal computing node 130 .

The cloud platform management system 100 can divide the storage area of the computing node 130 into an idle area and a working area according to the working state of the computing node 130 . When there is no computing node 130 in the idle area, that is, there is no idle computing node 130 , the control node 120 feeds back the status information of the computing node 130 to the monitoring node 110 to stop the migration process. When there are computing nodes 130 in the free area, there is an idle plan When computing the computing node 130, the control node 120 feeds back the status information of the computing node 130 to the monitoring node 110, so as to start the migration program.

The nova service is responsible for maintaining and managing the computing resources of the cloud platform management system 100 . The status of nova service includes normal status or abnormal status. When the nova service is in a normal state, the control node 120 feeds back the status information of the nova service to the monitoring node 110 to start the migration procedure. When the nova service is in an abnormal state, the control node 120 feeds back the status information of the nova service to the monitoring node 110 to stop the migration procedure.

The control node 120 can check the status of the power supply through a baseboard management controller (BMC). The baseboard management controller can perform operations such as upgrading the firmware of the machine and checking the machine equipment when the machine is not powered on. The state of the power supply includes on, off or standby state. When the power is turned on, the control node 120 feeds back the status information of the power to the monitoring node 110 to start the migration program. When the power is turned off or in standby state, the cloud platform management system 100 is offline, and the monitoring node 110 cannot receive the feedback message from the control node 120 .

The control node 120 records the state of the virtual machine on the computing node 130 in real time. The state of the virtual machine includes a running (Active) state or a failure (Error) state. After the migration of the virtual machine is completed, the control node 120 checks whether the state of the virtual machine is consistent with that before the migration, to determine whether to run a repair program to process the virtual machine, and feeds back the information of the virtual machine to the monitoring node 110 . When the state of the virtual machine after the migration is inconsistent with that before the migration, if the state of the virtual machine cannot be restored to the state before the migration after a certain period of time or after restarting the virtual machine, the control node 120 runs a repair program to repair the virtual machine. When the state of the virtual machine after migration is consistent with that before the migration, the control node 120 feeds back a message of successful migration of the virtual machine to the monitoring node 110 .

For example, the virtual machine is in the running state before the migration, and is in the fault state after the migration. If the virtual machine returns to the running state within 5 minutes or after restarting, the computing node 130 will feed back a message to the control node 120 that the virtual machine has migrated successfully. The control node 120 returns to the monitoring node 110 Feed the message of the successful migration of the virtual machine. Wherein, the control node 120 can run a restart program to restart the virtual machine. If the virtual machine is still in the failure state after more than 5 minutes or after being restarted, the computing node 130 feeds back a message that the migration of the virtual machine failed to the control node 120 . The control node 120 then feeds back a message of virtual machine migration failure to the monitoring node 110, and runs a repair program to restore the virtual machine.

In one of the implementation manners, after the migration of the virtual machine is completed, the monitoring node 110 displays the migration time of the virtual machine through the display screen. Wherein, the migration time of the virtual machine includes checking time, instance time and execution time. The check time refers to the time consumed by the control node 120 to check the status of the cloud platform management system 100 before the virtual machine is migrated. The value range of inspection time is 1min-5min. For example, the inspection time may be 2 minutes. The instance time refers to the time consumed by the control node 120 to invoke the instance before the virtual machine migration. The instance time is related to the number of instances and the time slot of instance calling. The value range of the time slot of instance calling is 1s-5s. For example, the time slot for calling an instance can be 5s, which means calling an instance every 5s. Execution time refers to the time consumed by virtual machine migration. The range of execution time is 30s-120s. For example, the execution time may be 60s.

For example, before the migration of the virtual machine, check time t ₁ =120s, time slot t ₀ of instance calling =5s, number of instances n=30, execution time t ₂ =60s, then the monitoring node 110 can calculate the Migration time T=t ₁ +t ₀ *n+t ₂ =330s.

In one of the implementation manners, the monitoring node 110 can store the work record of virtual machine migration. For example, the monitoring node 110 can write all or part of the virtual machine migration data into the evacuation_computeXX.log file, so as to provide effective data reference for operation and maintenance personnel to improve system performance.

In this embodiment, the cloud platform management system 100 realizes the real-time monitoring and control of the virtual machine migration process through the information interaction between the monitoring node 110 , the control node 120 and the computing node 130 . When the monitoring data meets the trigger conditions, the cloud platform management system 100 automatically starts the virtual machine migration work, which can automatically migrate the virtual machine away from the faulty node, restore it online, and promptly handle the exceptions encountered during the virtual machine migration process to reduce system downtime Machine time, improve the migration efficiency of virtual machines, Thereby improving the efficiency of operation and maintenance. After the migration of the virtual machine is completed, the operation and maintenance personnel can check the work records of the cloud platform management system 100 at any time to evaluate the effectiveness and reliability of the cloud platform management system 100 .

Wherein, the state of the computing node 130 includes a normal state or an abnormal state. The abnormal state includes the computing node 130 being disconnected or down. When the computing node 130 has an unexpected situation, such as disconnection or downtime, the monitoring node 110 captures the event and determines whether the computing node 130 meets the trigger condition.

In one of the implementation manners, the operation and maintenance personnel can select one or more monitoring nodes 110 to monitor the status of the computing nodes 130 .

S102, the monitoring node 110 determines whether the computing node 130 meets a trigger condition. If the computing node 130 satisfies the trigger condition, step S103 is performed. If the computing node 130 does not meet the trigger condition, return to step S101.

In one of the implementation manners, the trigger condition includes that the offline duration of the computing node 130 reaches a preset duration, or the status of the computing node 130 is unstable. Wherein, the value range of the preset duration is 1min-5min.

The disconnection of the computing node 130 includes the following four conditions: the nova-compute proxy service is disconnected, the number of nova-compute proxy services in the disconnected state is 1, the 10G network is disconnected and the 1G network is disconnected. When the above four conditions are met simultaneously, it may be determined that the computing node 130 is offline.

The unstable state of computing node 130 includes the following four conditions: the nova-compute proxy service is offline, the number of nova-compute proxy services in the offline state is 1, the 10G network is offline and the 10G network is in the offline state The number of computing nodes 130 is one. When the number of nova-compute proxy services in the offline state is 1, and the frequency of nova-compute proxy service offline reaches the first A preset frequency, and when the number of computing nodes 130 in the 10G network in the offline state is 1, and the frequency of 10G network offline reaches a second preset frequency, it can be determined that the status of the computing nodes 130 is unstable. Wherein, the value range of the first preset frequency is 8/10min-14/10min. The value range of the second preset frequency is 4/10min-7/10min.

When the computing node 130 meets the trigger condition, the monitoring node 110 sends a message to the control node 120 to migrate the virtual machine of the abnormal computing node 130 to other available computing nodes 130 .

S103, the monitoring node 110 sends a message to the control node 120 to migrate the virtual machine.

In one of the implementation manners, when the monitoring node 110 determines that multiple computing nodes 130 are abnormal, the virtual machines on each computing node 130 where the abnormality occurs are migrated sequentially, so as to reduce the need to migrate the virtual machines on one abnormal computing node 130 to another The status of an abnormal computing node 130 .

In one of the implementation manners, when the monitoring node 110 sends a message to the control node 120, the monitoring node 110 checks the thread flag and state lock of the control node 120 to reduce re-entry ) status.

S104 , the monitoring node 110 switches to the insurance state, so as to stop migrating virtual machines on other computing nodes 130 .

When the control node 120 starts to migrate a virtual machine on an abnormal computing node 130 , the monitoring node 110 switches to the insurance state, and stops migrating virtual machines on other abnormal computing nodes 130 . When it is determined that the migration of the virtual machine on an abnormal computing node 130 is completed, the monitoring node 110 switches back to the working state to continue monitoring the status of the computing node 130 .

S105, the monitoring node 110 displays the migration time of the virtual machine through the display screen.

Wherein, the migration time of the virtual machine includes checking time, instance time and execution time. The value range of inspection time is 1min-5min.

FIG. 4 is a flowchart of a virtual machine migration method according to another embodiment of the present application.

The virtual machine migration method can be applied to the control node 120 of the cloud platform management system 100 . Referring to Figure 4, the virtual machine migration methods include:

S201, the control node 120 checks whether there is an idle computing node 130. If there is an idle computing node 130, step S202 is executed. If there is no idle computing node 130, step S205 is executed.

In one of the implementation manners, the cloud platform management system 100 can divide the storage area of the computing node 130 into an idle area and a working area according to the working state of the computing node 130 . When there is a computing node 130 in the free area, that is, there is an idle computing node 130 , the control node 120 feeds back the status information of the computing node 130 to the monitoring node 110 to start the migration procedure.

After the control node 120 determines the idle computing node 130, it can establish a migration path from the source host to the target host, and then check whether the status of the nova service of the cloud platform management system 100 is normal. Wherein, the source host refers to the computing node 130 of the virtual machine to be migrated. The target host refers to the computing node 130 to receive the virtual machine.

When the nova service is in a normal state, the control node 120 feeds back the status information of the nova service to the monitoring node 110 to start the migration program. When the nova service is in an abnormal state, the control node 120 feeds back the status information of the nova service to the monitoring node 110 to stop the migration procedure.

S203, the control node 120 checks whether the status of the power supply is normal. If the state of the power supply is normal, step S204 is executed. If the state of the power supply is abnormal, execute step S205.

In one of the implementation manners, the control node 120 can check the status of the power supply of the cloud platform management system 100 through the baseboard management controller. Among them, the state of the power supply includes power on, power off or standby state. When the power is turned on, the control node 120 feeds back the status information of the power to the monitoring node 110 to start the migration program. When the power is turned off or in standby state, the cloud platform management system 100 is offline, and the monitoring node 110 cannot receive the feedback message from the control node 120 .

S204, the control node 120 starts a migration program.

When the control node 120 migrates the virtual machine, it checks the status of the cloud platform management system 100, including the above steps S201-S203. When the status of the cloud platform management system 100 is normal, the control node 120 starts the migration program.

S205, the control node 120 stops the migration program.

When the state of the cloud platform management system 100 is abnormal, the control node 120 stops the migration program.

S206, the control node 120 checks whether the state of the virtual machine is consistent with that before the migration. If the state of the virtual machine remains the same as before the migration, step S207 is executed. If the state of the virtual machine is inconsistent with that before the migration, step S208 is executed.

The control node 120 can record the state of the virtual machine on the computing node 130 in real time. Wherein, the state of the virtual machine includes a running state or a failure state.

In one of the implementation manners, after the migration of the virtual machine is completed, the control node 120 checks whether the state of the virtual machine is consistent with that before the migration.

S207, the control node 120 feeds back to the monitoring node 110 a message that the migration of the virtual machine is successful.

When the state of the virtual machine after migration is consistent with that before the migration, the control node 120 feeds back a message of successful migration of the virtual machine to the monitoring node 110 .

S208, the control node 120 determines whether the virtual machine needs to be repaired. If the virtual machine does not need to be repaired, step S209 is performed. If the virtual machine needs to be repaired, step S210 is performed.

When the state of the virtual machine after migration is inconsistent with that before migration, the control node 120 determines whether to repair the virtual machine.

It can be understood that when the state of the virtual machine after migration is inconsistent with that before migration, there are the following two situations: 1. The virtual machine goes down within a certain period of time, and after a period of time or after restarting, it can automatically return to the state before the migration . Second, if the virtual machine fails, if it is not repaired, it cannot be restored to the state before the migration.

S209, the control node 120 restarts the virtual machine.

When the above first situation occurs, there is no need to run the repair program, just restart the virtual machine or wait for the virtual machine to recover automatically. Wherein, the control node 120 can run a restart program to restart the virtual machine.

In one of the implementation manners, when the status of the virtual machine cannot be recovered after the virtual machine is restarted, the control node 120 feeds back a message that the migration of the virtual machine fails to the monitoring node 110, and executes step S210.

S210, the control node 120 repairs the virtual machine.

When the above second situation occurs, a recovery program needs to be run to recover the faulty virtual machine.
