Abstract:
1. A method of providing automated quality-of-service (‘QoS’) for virtual machine migration across a shared data center network, the method comprising: identifying, by a virtual machine migration module, a virtual machine to migrate from a source host to a destination host; determining, by the virtual machine migration module, a migration cost for migrating the virtual machine from the source host to the destination host including: identifying based on the migration cost, by the virtual machine migration module, a least congested network path between the source host and the destination host and a bandwidth to be used for migration; receiving a user specified time limit for completing the migration over the identified least congested network path; and initiating, by the virtual machine migration module, transmission of the virtual machine from the source host to the destination host over the least congested network path, including reserving bandwidth across the shared data center network for transferring the virtual machine from the source host to the destination host in dependence upon the migration costs,
