[0026] In the specific steps of the virtualization method of the physical server described in detail below, various embodiments of the present disclosure will be described more fully. The present disclosure may have various embodiments, and adjustments and changes may be made therein. However, it should be understood that there is no intention to limit the various embodiments of the present disclosure to the specific embodiments disclosed herein, but rather the present disclosure should be understood to cover all adjustments, equivalents and / or alternatives that fall within the spirit and scope of the various embodiments of the present disclosure.

[0027] Hereinafter, the terms "include" or "may include" used in various embodiments of the present disclosure indicate the presence of disclosed functions, operations, or elements, and do not limit the addition of one or more functions, operations, or elements. In addition, as used in various embodiments of the present disclosure, the terms "include", "have", and their cognates are intended only to indicate specific features, numbers, steps, operations, elements, components, or a combination of the foregoing, and should not be understood as first excluding the presence of one or more other features, numbers, steps, operations, elements, components, or a combination of the foregoing or the possibility of adding one or more features, numbers, steps, operations, elements, components, or a combination of the foregoing.

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] See also Figure 1 The figure is a flow chart of a method for virtualizing a physical server in a specific embodiment, the method comprising: S1: Perform a detailed assessment of the hardware configuration of the physical servers, analyze the applications and their dependencies, and configure the OpenStack platform.

[0030] In a specific implementation, first, a detailed evaluation is performed on the hardware configuration of the physical server. This includes but is not limited to key parameters such as CPU model, number of cores, memory size, hard disk type and capacity, network interface, etc. The purpose of the evaluation is to ensure that the target virtual machine can match or exceed the performance of the original physical server to avoid affecting business operations due to performance degradation. At the same time, the operating system version of the physical server must be checked to confirm whether it supports the type of virtual machine operating system running on the OpenStack platform. For unsupported operating systems, you may need to consider upgrading or replacing the operating system to ensure compatibility after migration.

[0031] Next, you need to conduct an in-depth analysis of the applications running on the physical server and their dependencies. This includes the application's installation package, configuration files, dependent libraries, database connections, etc. Through this step, you can assess the complexity and possible risks of the migration. For example, some applications may need to be reconfigured or adjusted in the new environment, and some dependent libraries may need to be reinstalled or updated on the OpenStack platform. In addition, you also need to pay attention to the application's data storage method to ensure the integrity and consistency of the data during the migration process.

[0032] Finally, in the target environment, install and configure the OpenStack platform, including the Keystone authentication service, Glance image service, Nova computing service, Neutron network service, Cinder block storage service and other core components. The collaborative work of these components will provide a stable operating environment for the virtual machine. During the configuration process, it is necessary to ensure the version compatibility of all components and the reasonable configuration of network, storage and other resources. In addition, the security of the OpenStack platform must be considered, such as setting appropriate access control policies and encrypted communications to ensure data security during the migration process.

[0033] S2: Back up the system disk and data disk of the physical server, generate an image file, convert the image file format, and transfer it to the OpenStack platform.

[0034] In a specific implementation, first, a professional P2V (physical to virtual) tool or a tool provided by the operating system is used on the physical server to perform a lossless backup of the entire system disk and data disk of the physical server. The purpose of this step is to generate an original image file containing all contents such as the operating system, application programs, and data. During the backup process, the integrity and consistency of the data must be ensured to avoid data loss or damage.

[0035] Next, convert the original image file obtained from the backup to an OpenStack-compatible virtual disk format, such as qcow2. This step usually requires the use of a specific conversion tool. During the conversion process, it is necessary to ensure the correctness and compatibility of the virtual disk format so that the virtual machine can recognize and load it. After the conversion is complete, the converted virtual disk file is securely transferred to the storage system of the OpenStack platform. During the transmission process, compression and encryption technologies can be used to improve transmission efficiency and security. At the same time, the transmission progress and status must be monitored to ensure the smooth progress of the transmission process.

[0036] S3: Create a virtual machine based on the OpenStack platform, mount the image file to the virtual machine, start the virtual machine, and perform network configuration and testing.

[0037] In a specific implementation, firstly, based on the graphical or command line interface of OpenStack, a virtual machine instance with corresponding specifications can be created according to the configuration information of the physical server. During the creation process, appropriate resources such as CPU, memory, and network card need to be allocated to meet the operation requirements of the virtual machine. At the same time, parameters such as the operating system type and version of the virtual machine need to be set to ensure consistency with the original physical server.

[0038] After creating a virtual machine instance, mount the converted and uploaded virtual disk file to the newly created virtual machine as a system disk or data disk for startup. This step is a key step in the migration process, which determines whether the virtual machine can successfully start and run the operating system and applications on the original physical server. During the mounting process, you need to ensure the correctness and compatibility of the virtual disk file and the correctness of the mount point. After starting the virtual machine, you need to check whether the operating system boots normally and confirm that all hardware (such as network cards and disks) are correctly identified and working.

[0039] Since network configuration is an important part of virtual machine configuration, you need to configure the network interface of the virtual machine, including the network card MAC address, IP address, subnet, routing and other parameters to ensure that the network environment of the virtual machine is the same as that of the physical server. After the configuration is completed, you need to perform a network test to verify whether the network connection of the virtual machine is normal and whether it can communicate with other devices on the original physical server.

[0040] S4: Verify the started operating system and applications in the virtual machine and perform business function testing.

[0041] In a specific implementation, after starting the virtual machine, you first need to check whether the operating system boots normally and confirm that all hardware is correctly identified and working. After entering the system, you need to check the integrity of the system files and confirm that key services (such as databases and web servers) can start and run normally. For some applications that require specific configuration or dependencies, additional configuration and testing are required.

[0042] Then, perform comprehensive business function testing, including simulating actual business scenarios and performing functional testing on the migrated virtual machines to ensure that they can completely replace the original physical servers without any business logic errors. During the testing process, attention should be paid to performance, response time, data accuracy, and other aspects.

[0043] S5: Adjust the hardware information of the virtual machine and dynamically adjust resources according to the business function test results.

[0044] In a specific implementation method, first, the specific situation of the business is obtained according to the business function test results, and the hardware information of the virtual machine is modified based on the specific situation of the business to ensure consistency with the original physical server. For example, some applications may rely on specific hardware information (such as MAC address, CPU model, etc.), which needs to be modified accordingly on the virtual machine. At the same time, attention should also be paid to the authorization issues of the original physical server to ensure that the migrated virtual machine can use the relevant software and services normally.

[0045] In addition, according to the business load, dynamically adjust the CPU and memory allocation of the virtual machine, and optimize the storage I / O performance to achieve the best operating efficiency. The OpenStack platform provides a variety of resource management tools that can monitor the resource usage of the virtual machine in real time and dynamically adjust it according to demand. In addition, you can also improve performance by optimizing the storage configuration and network configuration of the virtual machine.

[0046] S6: Ensure the security of data migration based on the high availability characteristics of the OpenStack platform, capture and synchronize incremental data of physical servers, perform integrity verification on incremental data, and set up performance monitoring and alarm mechanisms for virtual machines.

[0047] In the specific implementation, firstly, by utilizing the high availability features of OpenStack, such as automatic virtual machine migration, snapshot backup, and fault recovery, business continuity and data security can be enhanced. During the migration process, the automatic migration policy of the virtual machine can be set to ensure that it can be automatically migrated to other servers to continue running when a physical server fails. At the same time, snapshot backup operations need to be performed regularly so that data can be quickly restored when it is lost or damaged. In addition, attention should also be paid to data security, such as using encryption technology to protect the secure transmission and storage of sensitive data.

[0048] Secondly, during the migration process, it may be necessary to capture and synchronize the incremental data of the physical server to ensure the integrity and consistency of the data. At this time, use the log function of the file system or database to capture the data changes since the last synchronization, and use compression and encryption technology to package the incremental data into a transmission package and transmit it to the OpenStack platform through a high-speed network. On the OpenStack platform, you need to decompress the transmission package and apply the data to the corresponding location of the virtual server. At the same time, you also need to use a checksum or hash algorithm to verify the data blocks to ensure the integrity and accuracy of the data.

[0049] Third, set up a performance monitoring and alarm mechanism for virtual machines to promptly discover and handle potential problems and ensure stable business operations. Since the OpenStack platform provides a variety of monitoring tools, key indicators such as CPU usage, memory usage, disk I / O, and network traffic of virtual machines can be monitored in real time. By setting alarm thresholds and alarm methods (such as email notifications, SMS notifications, etc.), you can receive alarm information in a timely manner when indicators are abnormal and take corresponding treatment measures.

[0050] In this embodiment, efficient data migration and virtualization deployment are achieved by evaluating hardware configuration in detail, analyzing application dependencies, and configuring the OpenStack platform. The stability, reliability, and business continuity of the virtualization environment are significantly improved by backing up and converting image files, creating and testing virtual machines, flexibly adjusting resources, and using OpenStack's high availability to ensure data security and performance monitoring.

[0054] The data migration module 2 is used to back up the system disk and data disk of the physical server, generate an image file, convert the image file format, and then transmit it to the OpenStack platform.

[0056] The startup and verification module 4 is used to verify the started operating system and application program in the virtual machine and perform business function testing.

[0058] Data security module 6 is used to ensure the security of data migration based on the high availability characteristics of the OpenStack platform, capture and synchronize incremental data of physical servers, perform integrity verification on incremental data, and set up performance monitoring and alarm mechanisms for virtual machines.

[0059] The virtualization system of the physical server provided in this embodiment significantly improves the accuracy and efficiency of virtualization implementation through detailed hardware evaluation, application and dependency analysis, and clever configuration of the OpenStack platform. Through the image backup and format conversion of the system disk and data disk, seamless migration to the OpenStack platform is achieved, greatly simplifying the migration steps. The virtual machines created based on the platform not only start quickly, but also undergo careful network configuration and business function testing to ensure stable operation. At the same time, the system can flexibly adjust virtual machine resources based on test results, use the high availability of OpenStack to ensure data security, and set performance monitoring and alarms, which comprehensively enhances the stability of the system and business continuity, and provides a solid guarantee for data migration and virtualization deployment.
