Description

Technical Field

[0001] This invention relates to the field of virtualization systems, and in particular to a host upgrade method, apparatus, device, and medium. Background Technology

[0002] Virtualization systems often involve many modules, such as hosts, storage, and networks. Many updates require restarting the host to take effect, which will shut down the virtual machines running on it and cause business interruption. For many organizations and enterprises, the time window is usually short, and some core business operations cannot be interrupted. This requires that virtual machines be migrated to other hosts online before upgrading.

[0003] Currently, few virtualization products can achieve fully automated rolling upgrades. They require shutting down virtual machines or manual monitoring before the upgrade, with manual intervention at critical points to ultimately complete the system upgrade.

[0004] As can be seen from the above, how to avoid the situation where the host cannot be automatically rolled up during the virtualization process is a problem that needs to be solved in this field. Summary of the Invention

[0005] In view of this, the purpose of this invention is to provide a host upgrade method, apparatus, device, and medium that can complete unattended rolling upgrades of virtualization systems while ensuring uninterrupted service during upgrades, reducing labor costs and improving upgrade efficiency throughout the process.

[0017] The migration information of the migration task is recorded in a preset database.

[0019] Once all migration tasks of the preset virtual machine migration device are completed, the target upgrade host is upgraded, and the target upgrade host is restarted after the upgrade is completed.

[0020] Optionally, the step of migrating the virtual machine to be migrated to the target upgrade host based on the migration information after the target upgrade host restarts and meets the preset upgrade success conditions includes:

[0021] The target upgrade host is monitored using a preset host status detection device at a preset detection frequency.

[0022] When the preset host status detection device determines that the status of the target upgrade host after restarting meets the preset upgrade success conditions, the virtual machine to be migrated is migrated to the target upgrade host based on the migration information.

[0023] Optionally, when the preset host status detection device determines that the status of the target upgrade host after restarting meets the preset upgrade success conditions, the virtual machine to be migrated is migrated to the target upgrade host based on the migration information, including:

[0024] When the preset host status detection device determines that the target upgrade host has restarted and reconnected to the current system, and that the storage resource status and network status are both normal, the virtual machine to be migrated will be migrated to the target upgrade host based on the migration information.

[0025] Optionally, after determining the un-upgraded target upgrade host from the target hosts in the current system, the method further includes:

[0046] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0047] In existing technologies, virtualization systems require the virtual machines to be shut down or manually monitored before host upgrades. This manual intervention at critical points is labor-intensive and cannot achieve fully automated rolling upgrades. This application addresses this by enabling unattended rolling upgrades of virtualization systems while ensuring uninterrupted business operations. This reduces labor costs and improves upgrade efficiency throughout the process.

[0048] This invention discloses a host upgrade method, see [link to relevant documentation]. Figure 1 The method includes:

[0049] Step S11: When a rolling upgrade instruction is received, the target upgrade host that has not been upgraded is determined from the target hosts in the current system; the target host is the host that meets the preset rolling upgrade conditions among all hosts.

[0050] In this embodiment, the step of determining the un-upgraded target host from the target hosts in the current system when a rolling upgrade instruction is received may include: determining the un-upgraded target host from the target hosts in the current system when a rolling upgrade instruction triggered by a scheduled task or a one-click switch instruction is received.

[0051] Step S12: Migrate the virtual machines in the target upgrade host to the target migration host, and record the migration information in the preset database.

[0052] In this embodiment, the target upgrade host may be running virtual machines. To ensure uninterrupted service, the virtual machines will be migrated to other hosts before the host upgrade. In a specific implementation, a corresponding target migration host can be determined for each virtual machine in the target upgrade host, and then the virtual machine migration can be completed based on the mapping between virtual machines and target migration hosts. Since the virtual machines need to be migrated back to the current host after the host update is completed, migration information will be recorded at this time so that the virtual machines can be migrated back later based on the recorded migration information.

[0053] Step S13: Upgrade the target upgrade host and restart the target upgrade host after the upgrade is completed.

[0054] In this embodiment, the target upgrade host will be automatically restarted after the upgrade is performed so that the upgrade takes effect.

[0055] Step S14: When the target upgrade host restarts and meets the preset upgrade success conditions, the virtual machine to be migrated is migrated to the target upgrade host based on the migration information.

[0056] In this embodiment, when the target upgrade host restarts and meets the preset upgrade success conditions, the virtual machine to be migrated will be migrated back to the target upgrade host based on the migration information recorded in step S12. In specific implementations, the methods for determining whether the target upgrade host meets the preset upgrade success conditions after restarting include, but are not limited to, determining whether the target upgrade host's network has been restored, and determining whether the storage connected to the host has been successfully mounted.

[0057] Step S15: Re-determine the target upgrade host from the target hosts, and perform the step of migrating the virtual machines in the target upgrade host to the target migration host until there are no un-upgraded hosts in the target hosts.

[0058] It is understood that in this embodiment, migrating the virtual machine to be migrated to the target upgrade host indicates that the upgrade process of the current target upgrade host has been completed. Then, a new target upgrade host will be determined from the target hosts, and the upgrade of the next host will begin.

[0059] In this embodiment, after determining the un-upgraded target upgrade host from the target hosts in the current system, the process may further include: setting the target upgrade host to maintenance mode; correspondingly, after the target upgrade host restarts and meets the preset upgrade success conditions, the process may further include: exiting the maintenance mode of the target upgrade host.

[0060] In this embodiment, the step of re-determining the target upgrade host from the target host and performing the step of migrating the virtual machines in the target upgrade host to the target migration host, until there are no un-upgraded hosts in the target host, may further include: checking the health status of the upgraded system and automatically generating an inspection report for the user to view and understand. It should be noted that the process of checking the health status of the upgraded system and automatically generating an inspection report can be completed using a preset post-upgrade inspection device.

[0061] In this embodiment, upon receiving a rolling upgrade instruction, an un-upgraded target upgrade host is determined from the target hosts in the current system. The target host is a host among all hosts that meets the preset rolling upgrade conditions. Virtual machines in the target upgrade host are migrated to a target migration host, and the migration information is recorded in a preset database. The target upgrade host is upgraded, and restarted after the upgrade. When the target upgrade host restarts and meets the preset upgrade success conditions, the virtual machine to be migrated is migrated to the target upgrade host based on the migration information. A new target upgrade host is determined from the target hosts, and the step of migrating the virtual machines in the target upgrade host to the target migration host is executed until there are no un-upgraded hosts in the target hosts. Thus, by migrating the virtual machines in the target upgrade host to the target migration host and recording the migration information in the preset database, and by migrating the virtual machines to be migrated back to the target upgrade host based on the migration information after a successful host upgrade, and by repeatedly executing the step of determining the target upgrade host, rolling upgrades of system hosts can be achieved without manual intervention and without interrupting business operations.

[0062] Figure 2 This is a flowchart illustrating a specific host upgrade method provided in an embodiment of this application. See also... Figure 2 As shown, the method includes:

[0063] Step S21: When a rolling upgrade instruction is received, the target upgrade host that has not been upgraded is determined from the target hosts in the current system, and the target upgrade host is set to maintenance mode; the target host is the host that meets the preset rolling upgrade conditions among all hosts.

[0064] In this embodiment, before determining the target upgrade host that has not been upgraded from the target hosts in the current system, it may further include: determining all hosts in the current system, and checking the virtual machine status, storage resource status and network status of each host, so as to determine the host whose virtual machine status, storage resource status and network status meet the preset rolling upgrade conditions as the target host.

[0065] It is understood that in this embodiment, during the process of determining the target upgrade host from the target hosts in the current system, the host that meets the preset rolling upgrade conditions among all hosts will be identified as the target host first. In a specific implementation, the system resources will be checked first, such as the host status, storage devices, and whether the virtual machines running on the host support online migration, etc. Then, hosts whose resources do not support rolling upgrade will be investigated, and the host whose resources all meet the rolling upgrade conditions will be identified as the target host.

[0066] It should be noted that, in the preferred embodiment, the process of checking the system resources before the host upgrade can be completed by a preset pre-upgrade check device.

[0067] Step S22: Determine the target migration host for the virtual machines in the target upgrade host and generate migration pairing information.

[0068] In this embodiment, the target upgrade host may run multiple virtual machines, each of which needs to be migrated to another host. Therefore, before issuing the migration task in this step, resource scheduling is performed on the virtual machines on the current processing host, that is, finding an available target host for each virtual machine. If a virtual machine cannot be migrated, the upgrade cannot continue, and an error message will pop up for the user to identify. It should be noted that in this step, it must be ensured that each virtual machine running on the host corresponds to its target migration host.

[0069] In this embodiment, if the target migration host corresponding to each virtual machine is successfully determined, migration pairing information representing the correspondence between the virtual machine and the target migration host will be generated.

[0070] Step S23: Generate a migration task based on the migration pairing information and send it to a preset virtual machine migration device so that the preset virtual machine migration device can migrate the virtual machine in the target upgrade host to the target migration host.

[0071] In this embodiment, after generating migration pairing information, a migration task is generated based on the migration pairing information and sent to a preset virtual machine migration device. The migration device then executes the migration task to complete the migration of the virtual machine.

[0072] Step S24: Record the migration information of the migration task into a preset database.

[0073] In specific implementations, the task ID (i.e., identification, unique identifier) ​​of the migration task can be recorded in the database, and in some preferred implementations, the migration information can be stored in the preset database in tabular form.

[0074] Step S25: When all migration tasks of the preset virtual machine migration device are completed, the target upgrade host is upgraded, and the target upgrade host is restarted after the upgrade is completed.

[0075] In this embodiment, since multiple virtual machines may be running on the same target upgrade host, the preset virtual machine migration device will receive multiple migration tasks at the same time. When the preset virtual machine migration device has completed all the current migration tasks, it indicates that there are no virtual machines on the target upgrade host. At this time, the target upgrade host can be upgraded, and the host will be restarted after the upgrade is completed to make the upgrade effective.

[0076] It should be noted that, in the preferred embodiment, the process of upgrading the target upgrade host described above can be completed by a preset upgrade device, and the process of restarting the target upgrade host after the upgrade is completed can be completed by a preset host restart device.

[0077] Step S26: Use a preset host status detection device to perform status detection on the target upgrade host at a preset detection frequency.

[0078] It is understood that in this embodiment, the process of monitoring whether the preset upgrade success conditions are met after the target upgrade host restarts can be completed by the preset host detection device. Since the host restart in the previous step consumes a certain amount of time, the preset host status detection device in this step will continuously perform status detection on the target upgrade host according to a preset detection frequency.

[0079] Step S27: When the preset host status detection device determines that the target upgrade host has restarted and reconnected to the current system, and that the storage resource status and network status are both normal, the target upgrade host is taken out of maintenance mode, and the virtual machine to be migrated is migrated to the target upgrade host based on the migration information.

[0080] In a specific implementation, the preset host status detection device will continuously request to check whether the host has restarted successfully, whether the network has been restored, and whether the storage connected to the host has been successfully mounted according to the preset detection frequency. If the host restarts successfully, the network has been restored, and the storage connected to the host has been successfully mounted, it indicates that the storage resource status and network status are normal after the host restarts successfully. At this time, the virtual machine to be migrated can be migrated to the target upgrade host based on the migration information.

[0081] Step S28: Re-determine the target upgrade host from the target hosts, and perform the step of migrating the virtual machines in the target upgrade host to the target migration host until there are no un-upgraded hosts in the target hosts.

[0082] It should be noted that the migration of the virtual machine to be migrated to the target upgrade host in this step can also be completed by a preset virtual machine migration device.

[0083] Figure 3This is a schematic diagram of the overall process proposed in this invention. First, a resource check is performed on all resources within the system. If the resource check passes, it is determined whether there are any un-upgraded hosts among all hosts that meet the preset rolling upgrade conditions. If so, an un-upgraded host is identified and put into maintenance mode. Virtual machines on the host are scheduled and the migration information list is returned. After the virtual machine migration is completed, the host is upgraded, restarted to make the upgrade effective, and the host status is checked. Once the host has successfully restarted, its status is normal, and the host is connected to the system, the maintenance mode is exited, and the virtual machine migration is completed. This process is repeated to upgrade other hosts in the system that meet the preset rolling upgrade conditions. When it is determined that there are no un-upgraded hosts among the hosts that meet the preset rolling upgrade conditions, the system upgrade is complete. At this point, the system health status can be trained, and an inspection report can be generated for users to view and understand.

[0084] This embodiment proposes that when multiple virtual machines are running on the target upgrade host, resource scheduling is first performed on the virtual machines, and migration pairing information is generated. Then, the virtual machines are migrated based on the migration pairing information. During the process, it is necessary to ensure that each virtual machine has its corresponding target migration host to guarantee the rigor of the virtual machine migration process and ensure that no manual intervention is required during the migration. Furthermore, it proposes to use a preset pre-upgrade check device, a preset virtual machine migration device, a preset upgrade device, a preset host restart device, a preset host status detection device, and a preset post-upgrade inspection device to complete the rolling upgrade of the virtualization system, achieving unattended operation.
