<p>A virtual machine migration method, device and system. The method comprises: determining, by a first control node, a first address of an idle node in a first super node, wherein the idle node is a node having an idle resource in the first super node; and then, sending, by the first control node, the first address of the idle node to a first node, so that the first node migrates migration data blocks to a second node through the first address, wherein the migration data blocks are some data to be migrated to the second node from the first node, and the second node is arranged in a second super node. Therefore, data to be migrated in the first node is divided into a plurality of migration data blocks, and the migration data blocks are migrated to the second node from the first address of the first node through a corresponding idle node, thereby reducing the influence of virtual machine migration on the performance of other applications and virtual machines connected in a migration network. Further, scheduling as required is realized, and the utilization rate of idle resources in data is increased.</p> |
