Fair Unidirectional Multi-Queue Virtual Machine Migration

摘要

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.

主权项

1. A computer-implemented method, comprising:
maintaining, by a hypervisor executed by a processing device, a current scan identifier for each of a plurality of streams used in migrating a virtual machine; and adjusting, by the hypervisor, the migrating of the virtual machine when a current scan identifier of a first stream in the plurality of streams and a current scan identifier of a second stream in the plurality of streams are associated with different memory states of the virtual machine.
