背景技术Background Art
现有技术中，大多数虚拟化系统的更新升级需要提前跟客户预约时间窗口，此升级方法会造成虚拟机业务停机，而且在多架构的情况下通常需要经过多次操作，一个架构一个架构的去操作，最终完成虚拟化系统中所有主机的升级更新，对于用户来说，易用性比较差，而且人工操作难免会出错，造成维护成本的增加。In the prior art, the update and upgrade of most virtualization systems require an appointment window with the customer in advance. This upgrade method will cause the virtual machine business to be shut down, and in the case of multiple architectures, it usually requires multiple operations, one architecture at a time, to finally complete the upgrade and update of all hosts in the virtualization system. For users, the usability is relatively poor, and manual operations are inevitably prone to errors, resulting in increased maintenance costs.
因此，亟需提出一种能提高升级更新灵活性、易用性和可维护性的虚拟化系统更新方法、计算机设备、存储介质和程序产品。Therefore, there is an urgent need to propose a virtualization system update method, computer equipment, storage medium and program product that can improve the flexibility, usability and maintainability of upgrades and updates.

在一个实施例中，如图2-图3所示，提供了一种虚拟化系统更新方法，以该方法应用于图1中的终端为例进行说明，包括以下步骤：In one embodiment, as shown in FIG. 2-FIG 3, a virtualization system update method is provided, which is described by taking the method applied to the terminal in FIG. 1 as an example, including the following steps:
S1：获取至少一个更新包，并基于构建的待更新实体，从所述更新包中确定目标更新包，其中，所述虚拟化系统中包括至少一个待更新实体。S1: Acquire at least one update package, and determine a target update package from the update packages based on a constructed entity to be updated, wherein the virtualization system includes at least one entity to be updated.
需要说明的是，更新包是包含主机升级所需文件、脚本、配置信息等信息的一个压缩包，可以包括补丁包和升级包，待更新实体指的是需要升级或者打补丁的实体，可以包括管理节点、计算节点、数据中心、集群等，其由主机构成，如待更新实体为配置有更新参数的待更新主机，虚拟化系统由多个主机构成，虚拟化系统部署后在同一虚拟化环境中可能运行着多个数据中心，每个数据中心下也可能会部署着多个不同CPU（Central ProcessingUnit，中央处理器）架构的集群，例如x86_64或者aarch64，本申请包括管理节点（1台或者2台）和若干个计算节点，管理节点和计算节点上都运行着底层升级组件，管理节点不仅运行着底层升级组件，还包括平台层面的升级服务，完成整个升级任务的统一控制与任务调度。It should be noted that the update package is a compressed package containing files, scripts, configuration information and other information required for the host upgrade, which may include patch packages and upgrade packages. The entity to be updated refers to the entity that needs to be upgraded or patched, which may include management nodes, computing nodes, data centers, clusters, etc., which are composed of hosts. For example, the entity to be updated is a host to be updated configured with update parameters. The virtualization system is composed of multiple hosts. After the virtualization system is deployed, multiple data centers may be running in the same virtualization environment. Each data center may also be deployed with multiple clusters of different CPU (Central Processing Unit) architectures, such as x86_64 or aarch64. The present application includes a management node (1 or 2) and several computing nodes. The underlying upgrade components are running on both the management node and the computing node. The management node not only runs the underlying upgrade components, but also includes platform-level upgrade services to complete unified control and task scheduling of the entire upgrade task.
在一些具体实施方式中，如图4所示，在获取至少一个更新包之前，所述方法还包括：In some specific implementations, as shown in FIG4 , before obtaining at least one update package, the method further includes:
检测更新包的名称是否符合预设标准，即检查更新包命名是否符合规范，其中，规范一般指的是现有的服务器应用规范，在此不再赘述；Check whether the name of the update package meets the preset standard, that is, check whether the name of the update package meets the specification, wherein the specification generally refers to the existing server application specification, which will not be repeated here;
响应于检测到所述更新包的名称符合预设标准时，对所述更新包进行解压并解析，其中，解压和解析均为常用方法，在此不再赘述；In response to detecting that the name of the update package meets the preset standard, the update package is decompressed and parsed, wherein the decompression and parsing are both common methods and will not be described in detail here;
对解析后的更新包进行校验，其中，此处是对解析后的更新包的信息进行校验，一般为对包的完整性进行校验，其为常用的校验方法，在此不再赘述；Verify the parsed update package, wherein here the information of the parsed update package is verified, generally the integrity of the package is verified, which is a commonly used verification method and will not be described in detail here;
响应于检测到更新包已校验通过时，将解析后的更新包存储至主节点的数据库；In response to detecting that the update package has passed the verification, storing the parsed update package in the database of the master node;
同时，检测是否存在备节点；At the same time, check whether there is a backup node;
响应于检测到存在备节点时，将解析后的更新包同步至备节点的数据库；In response to detecting the existence of a standby node, synchronizing the parsed update package to a database of the standby node;
其中，主节点和备节点均有数据库服务，但是备节点的数据库服务一般处于关闭状态，只有主节点的数据库服务出于运行状态，若存在备节点时，将解析的信息同时同步至备节点的数据库中存储，以实现更新包信息的持久化。Among them, both the master node and the standby node have database services, but the database service of the standby node is generally in a closed state, and only the database service of the master node is in a running state. If there is a standby node, the parsed information will be synchronized to the database of the standby node for storage to achieve persistence of the update package information.
在一些具体实施方式中，所述待更新实体的构建方法包括：In some specific implementations, the method for constructing the entity to be updated includes:
获取实体的属性参数，并对所述属性参数进行筛选，得到用于更新的属性参数，其中，实体的属性参数一般指的是主机的规格参数，如硬件配置参数、性能指标参数和接口性能等，筛选出的参数一般是在主机更新时需要用到的参数，如内存信息、性能指标、版本号等参数；Acquire attribute parameters of the entity, and filter the attribute parameters to obtain attribute parameters for updating, wherein the attribute parameters of the entity generally refer to specification parameters of the host, such as hardware configuration parameters, performance index parameters and interface performance, etc. The filtered parameters are generally parameters required when the host is updated, such as memory information, performance index, version number and other parameters;
基于所述用于更新的属性参数与对应的实体形成的映射关系，生成所述待更新实体，即对实体构建详细的实体更新信息，并形成对应的映射关系，以生成待更新实体。Based on the mapping relationship formed between the attribute parameters for updating and the corresponding entities, the entity to be updated is generated, that is, detailed entity update information is constructed for the entity, and a corresponding mapping relationship is formed to generate the entity to be updated.
在一些具体实施方式中，所述目标更新包的确定方法包括：In some specific implementations, the method for determining the target update package includes:
获取待更新实体的属性参数；Get the attribute parameters of the entity to be updated;
基于所述待更新实体的属性参数，匹配数据库中的更新包，定义匹配成功的更新包为所述目标更新包，其中，此处一般是通过更新包的版本号、依赖版本号与待更新实体版本作比较看是否匹配，检查更新包适用的CPU架构与待更新实体的CPU架构是否匹配，以及更新包使用的产品类型与待更新实体的产品类型是否匹配等，匹配成功后，则定义匹配成功的更新包为目标更新包，并进行下载。Based on the attribute parameters of the entity to be updated, the update packages in the database are matched, and the successfully matched update package is defined as the target update package, wherein here, generally, the version number and the dependent version number of the update package are compared with the version of the entity to be updated to see whether they match, and whether the CPU architecture applicable to the update package matches the CPU architecture of the entity to be updated, and whether the product type used by the update package matches the product type of the entity to be updated, etc. After a successful match, the successfully matched update package is defined as the target update package and downloaded.
在上述实施方式中，通过构建待更新实体，可以准确快速地匹配到更新包，从而提高虚拟化系统更新效率和准确性。In the above implementation, by constructing the entity to be updated, the update package can be matched accurately and quickly, thereby improving the update efficiency and accuracy of the virtualization system.
S2：基于所述待更新实体的第一时间值和所述目标更新包的第二时间值，确定目标更新方式，其中，更新方式至少包括原地热升级、滚动热升级和冷升级，所述第一时间值用于描述待更新实体可用于重新启动的时长，所述第二时间值用于描述更新包的更新时长。S2: Based on the first time value of the entity to be updated and the second time value of the target update package, determine the target update method, wherein the update method includes at least in-place hot upgrade, rolling hot upgrade and cold upgrade, the first time value is used to describe the duration of the entity to be updated that can be used for restarting, and the second time value is used to describe the update duration of the update package.
需要说明的是，补丁包和升级包均支持原地热升级、滚动热升级以及冷升级三种升级方式，其中，补丁包的升级一般是原地升级，即所有更新的RPM包（RedhatLinuxPacketManager，Redhat的包管理器，是LINUX下的一种软件的可执行程序）都直接写入配置文件，RPM源文件也拷贝到升级到特定目录下，升级时直接调用RPM安装命令直接升级，升级包对应的原地热升级更新实现流程与补丁包的热升级一致，滚动热升级和冷升级在底层是在第二分区进行升级，升级成功后，重启主机后完成分区切换，进一步的，热或冷是针对虚拟机在升级过程中是否停机来说的，如果用户业务运行暂停一些时间，那么就建议采用冷升级方式，升级前或者重启前自动将运行的虚拟机关闭，等升级完成并重启后再将虚拟机自动启动；滚动热升级主要解决用户业务不能停，虚拟机不允许关闭的情况下，提供的一种方式，使用这种方式时，集群中的主机需要串行进行升级，升级某个主机前，先将上面运行的虚拟机迁移至其他主机，然后该主机升级并重启后，再将迁走的虚拟机迁回到该主机后，再继续升级下一台主机，最终再不影响虚拟机业务的前提下，完成集群中所有主机的升级，原地热升级在升级过程对待升级服务器的业务无影响，不需要提前迁移走业务资源。It should be noted that both patch packages and upgrade packages support three upgrade methods: in-place hot upgrade, rolling hot upgrade and cold upgrade. Among them, the upgrade of patch packages is generally in-place upgrade, that is, all updated RPM packages (Redhat Linux Packet Manager, Redhat's package manager, is an executable program of software under LINUX) are directly written into the configuration file, and the RPM source files are also copied to the specific directory to be upgraded. When upgrading, the RPM installation command is directly called to upgrade directly. The in-place hot upgrade implementation process corresponding to the upgrade package is consistent with the hot upgrade of the patch package. The rolling hot upgrade and cold upgrade are upgraded in the second partition at the bottom layer. After the upgrade is successful, the partition switching is completed after the host is restarted. Furthermore, hot or cold refers to whether the virtual machine is stopped during the upgrade process. For machines, if the user's business operation is suspended for some time, it is recommended to use the cold upgrade method. Before the upgrade or restart, the running virtual machine will be automatically shut down, and the virtual machine will be automatically started after the upgrade is completed and restarted; rolling hot upgrade is mainly used to solve the problem that the user's business cannot be stopped and the virtual machine is not allowed to be shut down. When using this method, the hosts in the cluster need to be upgraded serially. Before upgrading a host, migrate the virtual machines running on it to other hosts. Then, after the host is upgraded and restarted, migrate the migrated virtual machines back to the host, and then continue to upgrade the next host. Finally, under the premise of not affecting the virtual machine business, the upgrade of all hosts in the cluster is completed. In the process of upgrading, the in-place hot upgrade has no impact on the business of the upgraded server, and there is no need to migrate business resources in advance.
在一些具体实施方式中，基于所述待更新实体和所述目标更新包，确定目标更新方式包括：In some specific implementations, determining the target update mode based on the entity to be updated and the target update package includes:
获取所述待更新实体所属的业务场景，并基于所述业务场景，确定第一时间值，其中，通常可以基于大数据，来根据业务场景确定第一时间值，业务场景可以包括主机运行场景，如金融业务等，第一时间值一般指的是不同业务场景下，主机可以用于重新启动的时长，如金融业务场景下，通常要求虚拟机业务不能停机或者停机窗口时间有限，此时需要确定对应的第一时间值，以用于确定具体的更新方式；Acquire the business scenario to which the entity to be updated belongs, and determine the first time value based on the business scenario, wherein the first time value can usually be determined based on big data according to the business scenario, and the business scenario can include a host operation scenario, such as financial business, etc. The first time value generally refers to the length of time that the host can be used for restarting in different business scenarios. For example, in a financial business scenario, it is usually required that the virtual machine business cannot be shut down or the downtime window time is limited. At this time, it is necessary to determine the corresponding first time value to determine the specific update method;
获取所述目标更新包对应的第二时间值，其中，第二时间值指的是更新包进行更新时需要用的时间长度；Obtaining a second time value corresponding to the target update package, wherein the second time value refers to the length of time required for the update package to be updated;
响应于检测到所述第一时间值小于或等于第一预设阈值时，确定目标更新方式为滚动热升级或原地热升级，其中，第一预设阈值可以根据实际需求进行设置，优选的，第一预设阈值可以为0，即主机可以用于重新启动的时长为0，则选择的更新方式为滚动热升级或原地热升级；In response to detecting that the first time value is less than or equal to a first preset threshold, determining that the target update mode is a rolling hot upgrade or an in-place hot upgrade, wherein the first preset threshold can be set according to actual needs, preferably, the first preset threshold can be 0, that is, the time length that the host can be used for restarting is 0, and the selected update mode is a rolling hot upgrade or an in-place hot upgrade;
响应于检测到所述第一时间值大于第一预设阈值时，比较所述第一时间值和所述第二时间值；In response to detecting that the first time value is greater than a first preset threshold, comparing the first time value and the second time value;
基于比较结果，确定目标更新方式。Based on the comparison results, the target update method is determined.
在一些具体实施方式中，基于比较结果，确定目标更新方式包括：In some specific implementations, determining the target update method based on the comparison result includes:
响应于检测到所述第二时间值小于或等于第一时间值，且当前时刻距目标时刻的时间范围在预设时间范围内时，确定目标更新方式为冷升级，其中，目标时刻为主机可以用于重新启动的时刻，如凌晨3点等，预设时间范围可以根据实际需求设定，如30分钟、1小时等，若一些主机需要立马进行更新，则设定的时间范围可以为1分钟等等，在此不再赘述举例；In response to detecting that the second time value is less than or equal to the first time value, and the time range between the current time and the target time is within the preset time range, determining that the target update mode is a cold upgrade, wherein the target time is a time when the host can be used for restarting, such as 3 a.m., and the preset time range can be set according to actual needs, such as 30 minutes, 1 hour, etc. If some hosts need to be updated immediately, the set time range can be 1 minute, etc., and examples are not repeated here;
响应于检测到所述第二时间值大于第一时间值，且当前时刻距目标时刻的时间范围在预设时间范围内时，确定目标更新方式为冷升级，和，原地热升级或滚动热升级，其中，第二时间值大于第一时间值指的是更新时长大于可以重启的时长，此时，确定更新方式为冷升级，以及和原地热升级或滚动热升级其中的一种进行结合，冷升级为在可以重启时间段时进行的升级方式，原地热升级或滚动热升级为超出可以重启时间段进行的升级方式；In response to detecting that the second time value is greater than the first time value, and the time range between the current moment and the target moment is within the preset time range, determining that the target update mode is a cold upgrade, and an in-place hot upgrade or a rolling hot upgrade, wherein the second time value is greater than the first time value means that the update duration is greater than the restartable duration, at this time, determining that the update mode is a cold upgrade, and combining it with an in-place hot upgrade or a rolling hot upgrade, the cold upgrade is an upgrade mode performed during the restartable time period, and the in-place hot upgrade or the rolling hot upgrade is an upgrade mode performed beyond the restartable time period;
响应于检测到所述第一时间值大于第一预设阈值，且当前时刻距目标时刻的时间范围不在预设时间范围内时，确定目标更新方式为原地热升级或滚动热升级，即当前时刻距离目标时刻时间范围过长，若要等待冷升级可能会影响业务的处理速度等问题，此时，定义更新方式为原地热升级或滚动热升级。In response to detecting that the first time value is greater than a first preset threshold, and the time range between the current moment and the target moment is not within the preset time range, the target update mode is determined to be an in-place hot upgrade or a rolling hot upgrade, that is, the time range between the current moment and the target moment is too long, and waiting for a cold upgrade may affect the processing speed of the business. At this time, the update mode is defined as an in-place hot upgrade or a rolling hot upgrade.
在一些具体实施方式中，响应于检测到目标更新方式为原地热升级或滚动热升级时，所述方法还包括：In some specific implementations, in response to detecting that the target update mode is an in-place hot upgrade or a rolling hot upgrade, the method further includes:
响应于检测到需要进行业务资源迁移时，确定目标更新方式为滚动热升级，即根据业务场景的业务重要程度等信息，确定是否需要进行业务迁移，若用户业务不能停，虚拟机不允许关闭的情况，则采用滚动热升级方式进行更新；In response to detecting the need for business resource migration, determining the target update mode as rolling hot upgrade, that is, determining whether business migration is required based on information such as the business importance of the business scenario. If the user business cannot be stopped and the virtual machine is not allowed to be shut down, the rolling hot upgrade mode is used for update;
响应于检测到不需要进行业务资源迁移时，确定目标更新方式为原地热升级，同样的，若判断可以进行业务迁移，则采用原地热升级方式进行更新。In response to detecting that no business resource migration is required, the target update mode is determined to be an in-place hot upgrade. Similarly, if it is determined that business migration is possible, the in-place hot upgrade mode is used for updating.
具体的，在多架构的虚拟化环境下，即系统中的主机包括X86_64和aarch64时，系统可以通过上述方式自动过滤出两种架构对应的不同的可用更新包，下发更新任务后，后台在构建更新子任务时，将根据节点的架构类型选择适合该架构的更新包进行更新，以实现多架构环境下所有节点的更新，若选择了冷升级方式，则需要选择重启方式，默认是立即重启，也可以更改为手动重启或计划时间重启，若选择了滚动热升级，则重启方式只能是自动重启，并且可以调整集群中主机的顺序，选择主机顺序后，系统会进行升级前检查，检查所选的主机上运行的虚拟机是否都可以迁移至其他主机，滚动热升级要求系统中有足够的空闲资源，若空闲资源不足，则将不重要的虚拟机提前关闭。Specifically, in a multi-architecture virtualization environment, that is, when the hosts in the system include X86_64 and aarch64, the system can automatically filter out the different available update packages corresponding to the two architectures in the above manner. After issuing the update task, the background will select the update package suitable for the architecture according to the architecture type of the node when building the update subtask, so as to achieve the update of all nodes in the multi-architecture environment. If the cold upgrade method is selected, you need to select the restart method. The default is to restart immediately, which can also be changed to manual restart or scheduled restart. If rolling hot upgrade is selected, the restart method can only be automatic restart, and the order of hosts in the cluster can be adjusted. After selecting the host order, the system will perform a pre-upgrade check to check whether the virtual machines running on the selected hosts can be migrated to other hosts. The rolling hot upgrade requires sufficient free resources in the system. If the free resources are insufficient, unimportant virtual machines will be shut down in advance.
在上述实施方式中，通过时间值等相关信息确定对应的更新方式，以满足不用用户虚拟机业务的个性化需求，提高了更新方式选择的灵活性，极大地提高了易用性、易维护性及产品竞争力。In the above implementation, the corresponding update method is determined by time value and other related information to meet the personalized needs of different user virtual machine services, improve the flexibility of update method selection, and greatly improve usability, maintainability and product competitiveness.
S3：基于所述目标更新方式和所述目标更新包，控制所述待更新实体执行对应的更新任务。S3: Based on the target update mode and the target update package, control the entity to be updated to execute a corresponding update task.

响应于检测到虚拟化系统中存在已更新完成的待更新实体时，检测主备管理节点对应的待更新实体是否重启完成，其中，在虚拟化系统中，优先更新并重启属于主备管理节点的主机，若主备管理节点对应的待更新实体已全部重启完成，则继续更新重启其他节点的主机，此处的待更新实体为非主备管理节点所属的待更新实体；In response to detecting that there is an entity to be updated that has been updated in the virtualization system, detecting whether the entity to be updated corresponding to the active and standby management nodes has been restarted, wherein in the virtualization system, the hosts belonging to the active and standby management nodes are updated and restarted first, and if the entities to be updated corresponding to the active and standby management nodes have all been restarted, then continue to update and restart the hosts of other nodes, where the entity to be updated is the entity to be updated that does not belong to the active and standby management nodes;
响应于检测到主备管理节点对应的待更新实体均已重启完成时，安装第三方包、刷新引导项并关闭待更新实体中运行的虚拟机，其中，第三方包指的是非装机时安装的包，客户因为某种需要额外安装的组件，例如杀毒软件包等，引导项指的是指在启动主机时，用于选择不同操作系统版本或不同启动配置的一组菜单项；In response to detecting that the entities to be updated corresponding to the active and standby management nodes have all been restarted, installing a third-party package, refreshing the boot item, and shutting down the virtual machine running in the entity to be updated, wherein the third-party package refers to a package that is not installed during installation, and is a component that the customer needs to install additionally for some reason, such as an antivirus software package, etc., and the boot item refers to a group of menu items used to select different operating system versions or different startup configurations when starting the host;

在上述实施方式中，针对不同的迁移方式提出不同的迁移策略，实现从当前任意版本升级到最新版本，从而能够极大满足用户的个性化业务需求，提高了虚拟化系统更新的灵活性、易用性和可维护性。In the above implementation, different migration strategies are proposed for different migration methods to achieve upgrading from any current version to the latest version, thereby greatly meeting the personalized business needs of users and improving the flexibility, usability and maintainability of virtualization system updates.
在一些具体实施方式中，如图10所示，在迁移虚拟机之前，所述方法还包括：In some specific implementations, as shown in FIG10 , before migrating the virtual machine, the method further includes:
基于预设函数，计算确定虚拟机迁移后的存储池使用率，其中，所述预设函数包括：Based on a preset function, the storage pool usage rate after the virtual machine migration is calculated and determined, wherein the preset function includes:
； ;
其中，K表示虚拟机迁移后的存储池使用率，x表示存储池使用率，y表示存储池总容量，D表示当前虚拟机磁盘容量，f表示存储池总容量，该存储池指的是目标主机的存储池；Wherein,K represents the storage pool usage rate after the virtual machine is migrated,x represents the storage pool usage rate,y represents the total capacity of the storage pool,D represents the current virtual machine disk capacity,f represents the total capacity of the storage pool, and the storage pool refers to the storage pool of the target host;
响应于检测到所述虚拟机迁移后的存储池使用率大于第二预设阈值时，关闭目标数量的虚拟机，其中，第二预设阈值可以根据实际需求设置，如90%等，即存储池使用率不能高于某个值（如90%），避免迁移后因为存储池负载过高而导致虚拟机暂停。In response to detecting that the storage pool usage after the virtual machine migration is greater than a second preset threshold, a target number of virtual machines are shut down, wherein the second preset threshold can be set according to actual needs, such as 90%, that is, the storage pool usage cannot be higher than a certain value (such as 90%), to avoid virtual machine suspension due to excessive storage pool load after migration.
在一些具体实施方式中，所述目标数量的确定方法包括：In some specific embodiments, the method for determining the target quantity includes:
根据虚拟机的重要程度，按照从高到低的顺序对虚拟机进行排序，此处的虚拟机重要程度主要通过其处理的任务重要程度来判断，一般可以通过专业人员来评估对应的重要程度并进行排序，将重要程度较高的排在前面，重要程度较低的排在后面；Sort the virtual machines according to their importance from high to low. The importance of the virtual machines here is mainly determined by the importance of the tasks they process. Generally, professionals can evaluate the corresponding importance and sort them, with the more important ones being placed in front and the less important ones being placed in the back.
基于预设区间，对排序完成的虚拟机进行划分，得到多个虚拟机区间，并基于区间内的虚拟机重要程度之和，按照从高到低的顺序对虚拟机区间进行标记，其中，预设区间可以是以数值形式进行划分，如有100个虚拟机，那么预设区间对应的值为5，即按顺序，将5个虚拟机定义为一组，并进行标记，如第一个区间标记为20，第二个区间标记为19等等，其中，标记20对应的虚拟机区间的重要程度之和最大；Based on the preset intervals, the sorted virtual machines are divided to obtain multiple virtual machine intervals, and based on the sum of the importance of the virtual machines in the intervals, the virtual machine intervals are marked in descending order, wherein the preset intervals may be divided in numerical form, such as if there are 100 virtual machines, then the value corresponding to the preset interval is 5, that is, 5 virtual machines are defined as a group in order and marked, such as the first interval is marked as 20, the second interval is marked as 19, and so on, wherein the virtual machine interval corresponding to the mark 20 has the largest sum of importance;
根据所述虚拟机迁移后的存储池使用率与第二预设阈值之间的差值，确定存储池资源使用超出量，如虚拟机迁移后的存储池使用率为95%，第二预设阈值为90%，则存储池资源使用超出量为5%；Determine the excess amount of storage pool resource usage according to the difference between the storage pool usage rate after the virtual machine migration and the second preset threshold value. For example, if the storage pool usage rate after the virtual machine migration is 95% and the second preset threshold value is 90%, the excess amount of storage pool resource usage is 5%;
基于所述存储池资源使用超出量，按照从低到高的标记顺序确定需要关闭虚拟机的虚拟机区间，即将重要程度较低且迁移过去之后可能会导致负载过大的虚拟机进行关闭；Based on the excess usage of the storage pool resources, determine the virtual machine intervals that need to shut down the virtual machines in order of marking from low to high, that is, shut down the virtual machines that are less important and may cause excessive load after migration;
响应于检测到目标虚拟机区间中的虚拟机无需全部关闭时，根据当前存储池资源使用超出量以及目标虚拟机区间中每个虚拟机的资源占用量，匹配确定所述目标虚拟机区间中需要关闭的虚拟机，具体的，若根据存储池资源使用超出量以及每个虚拟机区间的虚拟机资源占用量，确定需要关闭的虚拟机区间为2个加上第三个虚拟机区间中的部分虚拟机，则判断关闭两个虚拟机区间的虚拟机之后，还剩余多少存储池资源使用超出量，根据该超出量选取出第三个区间内单个或累加后最接近的超出量的虚拟机，作为需要关闭的虚拟机，其中，此处优先比较单个虚拟机的资源占用量，之后再考虑多个虚拟机累加后的资源占用量，从而减少关闭的虚拟机数量，以避免出现业务数据丢失等问题；In response to detecting that all virtual machines in the target virtual machine interval do not need to be shut down, the virtual machines that need to be shut down in the target virtual machine interval are matched and determined according to the current excess storage pool resource usage and the resource occupancy of each virtual machine in the target virtual machine interval. Specifically, if it is determined that the virtual machine intervals that need to be shut down are 2 plus some virtual machines in the third virtual machine interval according to the excess storage pool resource usage and the virtual machine resource occupancy of each virtual machine interval, then it is determined how much excess storage pool resource usage remains after shutting down the virtual machines in the two virtual machine intervals, and according to the excess, a single virtual machine or a virtual machine with the closest excess after cumulative addition in the third interval is selected as the virtual machine that needs to be shut down, wherein the resource occupancy of a single virtual machine is compared first, and then the accumulated resource occupancy of multiple virtual machines is considered, thereby reducing the number of virtual machines to be shut down to avoid problems such as business data loss;
基于需要关闭的虚拟机，确定所述目标数量，即根据需要关闭的虚拟机确定对应的数量，如需要关闭2个虚拟机区间以及第三个虚拟机区间内的三个虚拟机，则对应的目标数量为13个。The target number is determined based on the virtual machines that need to be shut down, that is, the corresponding number is determined according to the virtual machines that need to be shut down. For example, if two virtual machine intervals and three virtual machines in the third virtual machine interval need to be shut down, the corresponding target number is 13.
在一些具体实施方式中，所述虚拟机的迁移方法包括：In some specific implementations, the virtual machine migration method includes:
获取待更新实体中当前正在运行的虚拟机，生成一一映射关系，并根据虚拟机的负载，按照从大到小的顺序进行排序，其中，虚拟机的负载可以根据内存计算逻辑内存、内存、CPU、磁盘的运行情况确定，对其进行排序以便于后续优先为高负载的虚拟机匹配目标主机，避免出现大配置虚拟机最后调度，找不到可用主机，阻止升级的情况；Get the currently running virtual machines in the entity to be updated, generate a one-to-one mapping relationship, and sort them in descending order according to the load of the virtual machine. The load of the virtual machine can be determined according to the operation status of the memory computing logic memory, memory, CPU, and disk. Sorting them is to facilitate the subsequent priority matching of the target host for the virtual machine with high load, so as to avoid the situation where the large configuration virtual machine is scheduled last and cannot find an available host, thus preventing the upgrade;
根据虚拟机的存储区域，确定虚拟机的迁移方式，其中，若虚拟机在共享存储上时，使用计算迁移，若虚拟机在本地存储上时，使用整机迁移，计算迁移只变更主机，整机迁移为跨主机跨存储迁移；Determine the migration method of the virtual machine based on the storage area of the virtual machine. If the virtual machine is on shared storage, use computing migration. If the virtual machine is on local storage, use whole machine migration. Computing migration only changes the host, while whole machine migration is cross-host and cross-storage migration.
获取目标实体列表，基于排序顺序和目标迁移方式，多线程地将所述虚拟机逐步迁移至目标实体，其中，目标实体指的是无需进行更新的主机，按照负载从大到小顺序及对应的迁移方式对虚拟机进行迁移。Obtain a list of target entities, and based on the sorting order and the target migration method, gradually migrate the virtual machines to the target entities in a multi-threaded manner, wherein the target entity refers to a host that does not need to be updated, and migrate the virtual machines in order of load from large to small and in a corresponding migration method.
具体的，在虚拟机进行迁移之前，获取主机运行虚拟机列表并创建虚拟机和目标主机集合，遍历虚拟机列表，同时，遍历非当前虚拟机所运行的非宿主机列表和当前虚拟机所运行的主机列表，基于虚拟机存储区域以及存储池等判断需要迁移的虚拟机，并将虚拟机和当前主机加入值配对结合中，此时，遍历配对集合并迁移对应虚拟机。Specifically, before the virtual machine is migrated, a list of virtual machines running on the host is obtained and a set of virtual machines and target hosts is created. The list of virtual machines is traversed. At the same time, a list of non-host machines where the current virtual machine is not running and a list of hosts where the current virtual machine is running are traversed. The virtual machines that need to be migrated are determined based on the virtual machine storage area and storage pool, and the virtual machines and the current host are added to the value pairing combination. At this time, the pairing set is traversed and the corresponding virtual machines are migrated.
进一步的，在虚拟机选择目标主机时，需满足以下原则：为避免虚拟机都迁往同一台主机导致排队耗时，在目标主机满足条件的情况下，尽可能将虚拟机分散迁移至不同主机，尽可能多地并发迁移更多虚拟机；主机上运行的虚拟机按照负载（内存计算逻辑内存，同时需要考虑内存、CPU、磁盘等）从高到底进行排序，优先为高负载的虚拟机匹配目标主机，避免出现大配置虚拟机最后调度，找不到可用主机，阻止升级的情况；升级过程中迁移虚拟机取消限速或者尽可能提高限速；共享存储上的虚拟机使用计算迁移，本地存储上的虚拟机使用整机迁移；计算存储池容量是否满足时，不仅考虑利用率，也考虑剩余容量，通过预设函数计算出虚拟机迁移后的存储池使用率，这个使用率越小优先级越高，最后的存储池使用率不能高于某个值（90%），避免迁移后因为存储池负载过高而导致虚拟机暂停；减少虚拟机迁移次数，一台虚拟机只迁移两次，即迁出和回迁；提供方式支持升级前进行迁移规划，并整理成特定格式的迁移规划配置文件，迁移虚拟机时优先根据该配置文件进行迁移。Furthermore, when a virtual machine selects a target host, the following principles must be met: To avoid queuing and wasting time when all virtual machines are migrated to the same host, if the target host meets the conditions, virtual machines should be migrated to different hosts as much as possible, and as many virtual machines as possible should be migrated concurrently; virtual machines running on the host should be sorted from high to low according to load (memory calculation logical memory, and memory, CPU, disk, etc. should also be considered), and target hosts should be matched with high-load virtual machines first to avoid the situation where large-configuration virtual machines are scheduled last and cannot find available hosts, thus preventing upgrades; during the upgrade process, the speed limit for migrating virtual machines should be canceled or increased as much as possible; on shared storage The virtual machines on the local storage use compute migration, and the virtual machines on the local storage use whole machine migration. When calculating whether the storage pool capacity is sufficient, not only the utilization rate but also the remaining capacity is considered. The storage pool utilization rate after the virtual machine migration is calculated through the preset function. The lower the utilization rate, the higher the priority. The final storage pool utilization rate cannot be higher than a certain value (90%) to avoid virtual machine suspension due to excessive storage pool load after migration. Reduce the number of virtual machine migrations. A virtual machine is migrated only twice, namely, migration out and migration back. Provide a method to support migration planning before upgrading, and organize it into a migration planning configuration file in a specific format. When migrating virtual machines, migration is performed according to this configuration file first.
更进一步的，本申请针对不同的升级方式配置对应的升级策略，在选择待更新实体和更新包后，系统会进行环境检测，检测通过，则会根据更新包信息以及所选的待更新实体具体情况给出建议的升级方式，不同的升级方式对应的升级策略也是不同的，例如冷升级支持配置重启方式，重启方式支持立即重启、手动重启和计划时间重启，滚动热升级支持集群中的主机调整升级顺序，并且滚动热升级在升级前会进行迁移前检查，如果存在某个节点的虚拟机不支持迁移到其他主机，则会报错提示用户，阻止升级，更新包的滚动热升级与冷升级，在更新后如果用户想回退，可以支持回退到上一个版本，只需刷新引导项，重启切换到原分区即可，更新任务下发后，支持轮播的形式展示升级详情，包括该任务所更新节点的各个更新关键步骤的开始时间、结束时间、状态、描述等信息，也会展示整个更新任务的总体进度以及总耗时时间，在更新成功后，会将各个节点的更新信息记录到更新历史中。Furthermore, the present application configures corresponding upgrade strategies for different upgrade methods. After selecting the entity to be updated and the update package, the system will perform an environmental test. If the test passes, it will give a recommended upgrade method based on the update package information and the specific situation of the selected entity to be updated. The upgrade strategies corresponding to different upgrade methods are also different. For example, cold upgrade supports the configuration of restart method. The restart method supports immediate restart, manual restart and scheduled restart. The rolling hot upgrade supports the hosts in the cluster to adjust the upgrade order, and the rolling hot upgrade will perform a pre-migration check before the upgrade. If the virtual machine of a certain node does not support migration to other hosts, an error will be reported to the user to prevent the upgrade. The rolling hot upgrade and cold upgrade of the update package, if the user wants to roll back after the update, it can support rolling back to the previous version. Just refresh the boot item and restart and switch to the original partition. After the update task is issued, it supports the display of upgrade details in the form of a carousel, including the start time, end time, status, description and other information of each key update step of the node updated by the task, and also displays the overall progress and total time of the entire update task. After the update is successful, the update information of each node will be recorded in the update history.
在上述实施方式中，通过对虚拟机需关闭个数进行确定，并在迁移之前关闭对应个数的虚拟机，避免迁移后因为存储池负载过高而导致虚拟机暂停，且多并发地对虚拟机进行迁移，避免出现大配置虚拟机最后调度，找不到可用主机，阻止升级的情况，提高了虚拟化系统更新的可靠性。In the above implementation, by determining the number of virtual machines that need to be shut down and shutting down the corresponding number of virtual machines before migration, it is avoided that the virtual machines are suspended due to excessive storage pool load after migration, and the virtual machines are migrated concurrently to avoid the situation where a large-configuration virtual machine is last scheduled and cannot find an available host, thereby preventing the upgrade, thereby improving the reliability of the virtualization system update.

The present application can be applied to a multi-architecture virtualization environment, and can provide different update methods and corresponding update strategies according to different environments and various update scenarios, thereby improving the flexibility of virtualization system updates, avoiding a series of problems caused by manual operation errors, improving the reliability and maintainability of virtualization system updates, and reducing costs.
