Cross-cloud-node migration system and cross-cloud-node migration method

The invention provides a cross-cloud-node migration system and a cross-cloud-node migration method. The system is applied to various of cloud nodes, a to-be-migrated virtual machine of a first cloud node sends a migration request, the system responds to the migration request to acquire configuration information of the to-be-migrated virtual machine and set an image file of the to-be-migrated virtual machine, the image file and the configuration information of the to-be-migrated virtual machine are packaged to form a package file which is stored in the first cloud node, the package file of the first cloud node is migrated to a target second cloud node, and the second cloud node reads the configuration information in the migrated package file to create a new blank virtual machine and recover the image file to the new blank virtual machine. The cross-cloud-node migration system provides a series of paid cloud services of expected sensitive data synchronization and backup, accessible utilization and compatible share of data, applications and even operating systems in different cloud nodes for users.
