RELIABLE AND DETERMINISTIC LIVE MIGRATION OF VIRTUAL MACHINES

摘要

Technologies for live virtual machine migration include a plurality of compute nodes and a datacenter manager. The datacenter manager issues a request to migrate a virtual machine to a source compute node. The request includes a service level requirement such as a maximum migration time or downtime. The source compute node determines platform resources required to perform migration within the service level requirement and reserves the platform resources for a predicted migration time. The source compute node transfers virtual machine state to a destination compute node and releases the platform resources after the transfer is complete. The source compute node may use a hardware resource monitor or reservation manager to determine available platform resources and reserve the platform resources for exclusive use. If sufficient platform resources are not available, the source compute node may negotiate reduced service level requirements with the datacenter manager. Other embodiments are described and claimed.

1. A compute node for migrating a virtual machine, the compute node comprising:
a virtual machine migration module to receive a request to migrate a virtual machine to a destination compute node, wherein the request includes a service level requirement; a service level management module to determine platform resources required to migrate the virtual machine and satisfy the service level requirement; and a resource management module to (i) determine whether the required platform resources are currently available to the compute node and (ii) reserve the required platform resources for a predicted migration time in response to a determination that the required platform resources are currently available; wherein the virtual machine migration module is further to migrate, in response to reservation of the required platform resources, the virtual machine to the destination compute node using the reserved platform resources.
