Abstract
The invention provides a method and a device based on Xen for monitoring the thermomigration progress for a virtual machine. The device comprises a first agent arranged on an original host machine and a second agent arranged on an objecitve host machine. The method comprises the steps as follows: the first agent initiates a migration request of the virtual machine, and a unique mark of the virtual machine to be migrated is carried in the request; the second agent creates a casing with the same name and the same configurations for the virtual machine to be migrated according to the migration request of the virtual machine; the first agent initiates the migration of the virtual machine, and leads internal storage of the virtual machine to be migrated to the casing; and the second agent acquires the internal storage increments of the virtual machine in the casing, so as to calculate the migration speed of the virtual machine. By adopting the method, the migration progress in the migration process of the virtual machine can be obtained without modification to the Xen part at a bottom layer.
