TECHNOLOGIES FOR VIRTUAL MACHINE MIGRATION

摘要

Technologies for virtual machine migration are disclosed. A plurality of virtual machines may be established on a source node at varying tiers of quality-of-service. The source node may identify a set of virtual machines from the plurality of virtual machines having a lower or lowest tier of quality-of-service. Additionally, the source node may perform a pseudo-migration for each of the virtual machines of the identified set to determine a dynamic working set for each corresponding virtual machine. The source node may select a virtual machine for migration based on the dynamic working set. The pseudo migration may include emulation of a pre-copy phase of a corresponding live migration to identify the number of dirty memory pages likely to result during the corresponding live migration of the corresponding virtual machine.
