Abstract:
Methods, systems, and computer program products for providing fair unidirectional multi-queue virtual machine migration are disclosed. A computer-implemented method may include maintaining a current scan identifier for each of a plurality of streams used to migrate a virtual machine from a first hypervisor to a second hypervisor, determining when a current scan identifier of a first stream and a current scan identifier of a second stream are associated with different memory states of the virtual machine, and adjusting processing of memory updates when the current scan identifiers are associated with different memory states of the virtual machine. The adjusting may be performed, for example, by pausing processing on each stream having a current scan identifier subsequent to the earliest current scan identifier determined for the streams, and processing memory updates on each stream having a current scan identifier matching the earliest current scan identifier.
