The virtual machine migration method provided by the embodiment of the application is applied to an HCI platform and can comprise the following steps:
Step S101: responding to a virtual machine migration instruction.
In practical applications, before the virtual machine is migrated to the HCI platform, a virtual machine migration instruction is generally sent to the HCI platform, so that the HCI platform needs to perform virtual machine migration, so that the HCI platform needs to receive the virtual machine migration instruction and respond to the virtual machine migration instruction to execute the responding virtual machine migration operation.
Step S102: and copying the data of the virtual machine to be migrated to obtain a virtual machine mirror image.
In practical application, in the process of executing virtual machine migration operation, the HCI needs to copy data of the virtual machine to be migrated because the virtual machines before and after migration are the same, so as to obtain a virtual machine image, and then restart the virtual machine based on the virtual machine image, so as to realize migration of the virtual machine.
