[0010] Step 4: Copy memory and running status and process input and output requests at the same time: The source host starts to copy the memory status and running status of the virtual machine to the target host, and the source host continues to process the input and output requests of the virtual machine;

[0011] Step 5: Transfer control: After the memory status and running status are copied, the source host transfers the control of the virtual machine to the target host;

[0012] Step 6: Take over the operation of the virtual machine: The target host takes over the operation of the virtual machine and completes the virtual machine migration process;

[0013] Step 7: Release resources: The source host releases resources related to the virtual machine for use by other virtual machines;

[0014] Step 8: Monitor virtual machine performance: Monitor the performance of the virtual machine after migration through the virtualization management layer to ensure stable operation of the migrated virtual machine;

[0015] Step 9: Automatic exception handling: If the migrated virtual machine runs abnormally, the virtualization management layer will automatically trigger the rollback mechanism and migrate the virtual machine back to the source host to ensure business continuity.

[0016] Preferably, initiating the migration and sending a request in the first step further comprises performing a compatibility check on the source host and the target host to ensure that the target host has the hardware and software environment required to run the virtual machine.

[0017] Preferably, the pre-allocation of resources in the second step further includes optimizing the configuration of resources of the target host to improve the performance of the virtual machine after migration.

[0036] The working principle of the present invention is to achieve seamless migration of virtual machines through a series of carefully designed steps. Virtual machine migration refers to the process of migrating a running virtual machine from one physical host to another without causing significant impact on the applications and users on the virtual machine. In the first step, the virtualization management layer on the source host will start the migration process and send a migration request to the target host. This process not only includes a compatibility check of the source host and the target host, but also involves a detailed evaluation of the current running state of the virtual machine to ensure the feasibility of the migration. In the second step, after receiving the migration request, the target host will pre-allocate resources. This step not only includes the preparation of computing resources and storage resources, but also includes optimizing the resources of the target host to improve the performance of the virtual machine after migration. Resource optimization configuration may involve adjusting the allocation ratio of CPU, memory and storage to meet the specific needs of the virtual machine. In the third step, a high-speed data transmission channel is established between the source host and the target host. In addition to ensuring the efficiency of data transmission, the data transmission channel will also be encrypted to ensure data security during the migration process. Encryption technology can use existing security protocols, such as SSL / TLS, to prevent data from being intercepted or tampered with during transmission. In the fourth step, the source host begins to copy the memory state and running state of the virtual machine to the target host. At the same time, the source host continues to process the input and output requests of the virtual machine to ensure that the virtual machine provides continuous services to the outside world during the migration process. In addition, the network state of the virtual machine is synchronized to ensure that the network connection of the virtual machine is not interrupted during the migration process. In the fifth step, after the memory state and running state are copied, the source host transfers the control of the virtual machine to the target host. This step also includes synchronization confirmation of the source host and the target host to ensure seamless transfer of control of the virtual machine. The synchronization confirmation mechanism can use heartbeat signals or status confirmation messages to ensure the reliability of the migration process. In the sixth step, the target host takes over the operation of the virtual machine. During the takeover process, the performance of the virtual machine on the target host will be tuned to adapt to the new operating environment. Performance tuning may include adjusting the CPU affinity, memory allocation strategy, and I / O scheduling strategy of the virtual machine. In the seventh step, the source host releases the resources related to the virtual machine for use by other virtual machines. Releasing resources also includes backing up the relevant resources on the source host so that they can be quickly restored when an exception occurs during the migration process. The backup mechanism can use snapshot technology to ensure data integrity and consistency. In step 8, the performance of the migrated virtual machine is monitored through the virtualization management layer. The monitoring process not only ensures the stable operation of the migrated virtual machine, but also involves real-time analysis of the virtual machine performance indicators to promptly identify and resolve potential problems. In step 9, the automatic exception handling mechanism is triggered when an exception occurs in the operation of the migrated virtual machine. The rollback mechanism is automatically triggered to migrate the virtual machine back to the source host to ensure business continuity.The exception handling mechanism also includes detailed records of abnormal situations for subsequent problem analysis and optimization and improvement. By optimizing the virtual machine migration process, the data center can respond to changes in business needs more flexibly, improving the scalability and flexibility of the system. The optimized virtual machine migration method can not only reduce the demand for network bandwidth and reduce the energy consumption of the data center, but also improve the green energy saving level of the data center, providing a strong guarantee for the efficient operation of modern data centers.
