And the virtual machines across the data center are migrated, and the storage networks of the two places are isolated, so that the migration of the disk file nodes is completed by the mutual cooperation of the two hosts in the two cloud platforms depending on the management network. Therefore, the cross-cloud platform can finish the complete machine migration of the virtual machine under extreme conditions without depending on a storage network.
The cross-platform migration scheme is exported through the importation of fig. 5 and fig. 6, as well as the intra-platform virtual machine migration and the cross-cloud platform migration of fig. 9. The advantages of the scheme can be summarized as follows:
(1) the operation flow is fully automatic, and the platform can finish the migration operation of the virtual machine only by adding the virtual machine to be migrated into the list to be migrated and setting the start time and the end time of the migration;
(2) the migration does not change the structure of a disk file chain, so that the special characteristics of the difference can be kept, such as the restoration function of a virtual machine and the like;
