[0055] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0056] With the rise of cloud computing, the widespread application of cloud computing and virtualization technology has provided enterprises with greater flexibility, efficiency and reliability, and has become a key component of existing infrastructure. Due to various reasons such as enterprise cloud migration, upgrading, resource upgrades, etc., migrating hosts in different environments to cloud computers that are more convenient to use and have richer resources has become a new demand.

[0057] In response to the need to migrate to cloud computers, the current mainstream technical solutions are to use image import, that is, the source virtual host first generates image files such as vmdk through a virtual machine (such as VMware), and then uses the underlying virtualization technology of the cloud computer to import the image to generate a new target cloud computer, thereby realizing the cloud computer migration needs. However, since physical machines cannot directly generate image files, this method is quite limited in the scenario of migrating physical machines to cloud computers. The second is to use a transit server (also called a shadow server) to adapt some drivers on the transit server. This solution consumes a lot of resources and has poor adaptability.

[0058] In one embodiment, Figure 1As shown, a cloud computer migration method is provided. This embodiment uses the method applied to a terminal as an example for illustration. It can be understood that the method can also be applied to a server, and can also be applied to a system including a terminal and a server, and is implemented through the interaction between the terminal and the server. In this embodiment, the method includes the following steps:

[0059] Step 101, determining whether the source host supports migration to the target cloud computer, and if so, locking the target cloud computer and controlling the target cloud computer to enter rescue mode;

[0060] Step 102, backing up the system boot file of the target cloud computer and generating a system snapshot of the source host;

[0061] Step 103, transmitting the system snapshot to the target cloud computer, and performing preliminary adaptation between the source host and the target cloud computer based on the system type of the source host;

[0062] Step 104, if the initial adaptation is successful, restore the system boot file and exit the rescue mode;

[0063] Step 105, performing secondary adaptation on the source host and the target cloud computer, completing the current migration when the secondary adaptation is successful, and unlocking the target cloud computer.

[0064] Exemplarily, computer migration refers to migrating the entire operating system, configuration, and applications of one computer to another computer. The cloud computer migration described in this article specifically refers to migrating the source host (including physical machine / virtual machine / cloud computer) to the cloud computer as a whole. Rescue mode is a special startup mode that comes with a cloud computer and is used by the operating system for troubleshooting and repair. It usually loads minimal system resources and drivers to ensure that the original system can still start and run normally in a faulty state. A snapshot refers to a fully usable copy of a specified data set, which includes an image of the corresponding data at a certain point in time. In the cloud computer migration method of this embodiment, two adaptations are performed to ensure the normal operation of system applications. The specific adaptation method will be described later.

[0065] For example, see Figure 2 This embodiment adopts Figure 2 The overall architecture is mainly composed of the management console, migration agent, synchronization node and proxy. The functions of each part include:

[0066] The management console is used to coordinate and manage the process scheduling of cloud computer migration, collect the status and progress of various migration tasks, issue various instructions, and also rely on internal capabilities to implement related operations on the target cloud computer (such as creating a cloud computer, mounting disks, switching to rescue mode, etc.);

[0067] Migration agent: It is used to receive various instructions issued by the execution management console, report task status, and perform specific migration operations;

[0068] Synchronization node, used to open up a channel between the source host and the target cloud computer for migration;

[0069] Proxy (proxy mode): used to connect the national region with the target resource pool network;

[0070] The main network links are divided into two categories:

[0071] Migration network: The migration agent of the source host and the migration agent of the target cloud computer register with the migration nodes deployed in the national region through the external network, establish a long connection, and open up the migration channel. It should be noted that if the target cloud computer does not have external network capabilities, it needs to register with the migration node through a proxy.

[0072] Scheduling network, the migration agent of the source host is registered with the management console deployed in the national region through the external network, and the migration agent of the target cloud computer is registered with the management console deployed in the national region through the external network. Similarly, if the target cloud computer does not have external network capabilities, it needs to register with the management console through a proxy.

[0073] The main process is divided into four stages: inspection, preparation, migration, and adaptation. The source host runs normally without the user noticing, and the target cloud computer switches between rescue mode and normal operating mode.

[0074] In the above-mentioned cloud computer migration method, a migration method based on the file system level in the native rescue mode of the cloud computer is adopted, which can solve the problem of storage resource waste based on the rescue mode capability of the cloud computer itself; it supports a wide range of application scenarios and can realize heterogeneous migration in a variety of environments, allowing users to seamlessly migrate physical machines, virtual machines, and (non-) homologous cloud computers to cloud computers. At the same time, it has a highly compatible driver adaptation strategy that can realize automatic identification, dynamic loading and abnormal rollback of drivers. Without occupying additional resources, a heterogeneous migration service with high driver adaptability is realized.

[0075] In an exemplary embodiment, determining whether the source host supports migration to the target cloud computer includes: respectively obtaining host information of the source host and the target cloud computer, and determining whether the source host supports migration to the target cloud computer based on the host information, wherein the host information includes at least the host system type and disk partition information.

[0076] Specifically, this step corresponds to the inspection phase above. The source host and the target cloud computer report host information respectively, mainly including the host system type (physical machine / virtual machine / cloud computer) and disk partition information, etc., to determine whether the current machine supports migration to the cloud computer; at the same time, identify the hardware driver of the source host and clarify the one-to-one correspondence between the source host and the target cloud computer's disk.

[0077] At this time, the target cloud computer is in normal operating mode, and then the target cloud computer is locked to prevent users from logging in and enters the rescue mode.

[0078] In this embodiment, the rescue mode can handle the write operation of the original system disk. When the target cloud computer is in the rescue mode, it is booted as the rescue minimum system, and the original system disk is mounted as a normal data disk, which is convenient for data transmission and overwriting without worrying about permission issues.

[0079] In an exemplary embodiment, before transferring the system snapshot to the target cloud computer, the steps include: after backing up the system boot file of the target cloud computer, formatting the original system partition of the target cloud computer, and notifying the source host that the target cloud computer is ready.

[0080] Specifically, we enter the preparation stage of cloud computer migration: to pave the way for the formal migration, the target cloud computer performs backup, formatting and other preparatory operations in rescue mode during this stage; the backup is to back up the original system boot files (such as bootnxt, etc.), and restore them during the adaptation stage to prevent the inconsistency between the two systems from causing the target cloud computer to fail to boot normally; the source host actively generates a temporary system snapshot through the Volume Shadow Copy Service (VSS) that comes with the Windows system to ensure system consistency and solve the problem of read permissions for some system files.

[0081] In an exemplary embodiment, the transmitting the system snapshot to the target cloud computer includes:

[0082] Obtain a file transfer tool, control the source host to transfer the system snapshot based on the client of the file transfer tool; control the target cloud computer to monitor the transmission process of the system snapshot based on the server of the file transfer tool.

[0083] Cloud PC migration based on the file system: the source host transfers the snapshot content to the target cloud PC in the form of file transfer (customized fsync transmission technology or other file transfer technologies can be used).

[0084] In this embodiment, migration based on the file system and system image can avoid the problem that the physical machine cannot directly generate an image file, and there is no need to use a transit server. Data can be directly transmitted between the source host and the target cloud computer without occupying a large amount of resources.

[0085] In an exemplary embodiment, the preliminarily adapting the source host and the target cloud computer based on the system type of the source host includes:

[0086] Determine whether the system type of the source host is the same as the system type of the target cloud computer; if they are different, obtain an adapter driver, and perform preliminary adaptation of the source host and the target cloud computer based on the adapter driver.

[0087] After the migration is completed, in order to ensure the normal operation of the system application, some adaptation processing needs to be performed on the target cloud computer. Part of the adaptation stage is carried out in rescue mode, and some operations cannot be installed offline and need to be switched to normal operating mode and then automatically executed after startup. Based on this, this application divides the adaptation stage into preliminary adaptation and secondary adaptation. Specifically, the preliminary adaptation includes: in rescue mode, the target cloud computer automatically installs hardware drivers according to the driver information reported by the source host based on whether the source host is a cloud computer, to ensure that the migrated system can start normally-usually install viostor and vioscsi, and dynamically and selectively install drivers such as netkvm. If the adaptation is abnormal, it can also be rolled back to a stable state to ensure system reliability. In addition, it is necessary to restore the system boot files backed up in the preparation stage, and the offline registration service automatically performs secondary adaptation after entering the normal operating mode and starting up.

[0088] In an exemplary embodiment, the secondary adaptation of the source host and the target cloud computer includes:

[0089] Determine whether the system type of the source host is the same as the system type of the target cloud computer; if the two are different, automatically start the adapter component when the target cloud computer is turned on; wherein the adapter component is used to initialize the service and personalize the target cloud computer.

[0090] Exemplarily, the adaptation component refers to the cloud computer custom component. At this point, the rescue mode has been exited and the normal operation mode has been entered. In the normal operation mode, the target cloud computer installs the cloud computer custom component according to whether the source host is a cloud computer. Exemplarily, the functions of the custom component include: completing initialization services including automated network settings, patch update installation, storage volume management configuration, etc., while performing personalized settings such as virtual printing and program performance optimization, to solve the problem of incompatibility of cloud computer basic services due to lack of plug-ins after physical machine / virtual machine migration;

[0091] In this embodiment, the problem of compatibility between different types of source hosts (mainly physical machines / virtual machines) after migration to cloud computers is solved through custom components, and a heterogeneous migration service with high driver adaptability can be implemented without occupying additional storage resources.

[0092] To explain the cloud computer migration method in detail, the following is a most detailed example:

[0093] See also Figure 3 , Figure 3 A flowchart of a specific implementation method provided for this application: This application can be applied to scenarios of migration to cloud computers in different environments (physical machines / virtual machines / cloud computers). For ease of explanation, a specific implementation example is given for the scenario of VMware virtual machines migrating to cloud computers.

[0094] Inspection phase:

[0095] Install the migration agent on the VMware virtual machine, register it to the console and create a migration task; the virtual machine reports the host information (including system type, disk partition, system architecture, etc.) and driver information.

[0096] If migrating to a new machine, a cloud computer will be created based on the host information of the VMware virtual machine; if migrating to an existing cloud computer, it will be determined whether it meets the migration conditions. The cloud computer will be locked into rescue mode to prevent users from logging in.

[0097] Preparation stage:

[0098] The target cloud computer backs up the original system boot files (bootnxt, bootmgr, boot\) to the specified directory of the current boot disk, and restores them in the adaptation phase to ensure that the cloud computer can boot normally after the subsequent migration. The target cloud computer formats the original system partition. The VMware virtual machine generates a VSS temporary snapshot to ensure system consistency and solve some system file read permission issues that may arise during the subsequent migration process.

[0099] Migration phase:

[0100] The target cloud computer starts the fsync (fsync is a custom file transfer tool that is optimized for transfer efficiency and Windows file attributes) server to monitor the transfer process, and the VMware virtual machine starts the fsync client to start the migration of the system snapshot. For example, file transfer can also be implemented using other file transfer tools such as rsync.

[0101] Adaptation phase:

[0102] The target cloud computer installs viostor and vioscsi drivers according to the driver information reported by the VMware virtual machine during the inspection phase; at the same time, registers the offline service Bootstrap for self-starting installation of cloud computer custom components. Restore the system boot files backed up in the preparation phase to the original system.

[0103] Then, the target cloud computer exits the rescue mode and enters the normal operation mode. The target cloud computer automatically starts to install the cloud computer custom component (named ctyun_xx_mirror_xx.exe, which includes the installation of components such as clinkagent, cloudupdate, virtualprinter and other personalized configurations) to adapt the operation of the cloud computer. After the adaptation is completed, the target cloud computer is unlocked and locked, the migration is completed, and the user can log in and use it.

[0104] It should be understood that, although the various steps in the flowcharts involved in the above-mentioned embodiments are displayed in sequence according to the indication of the arrows, these steps are not necessarily executed in sequence according to the order indicated by the arrows. Unless there is a clear explanation in this article, the execution of these steps does not have a strict order restriction, and these steps can be executed in other orders.
