Patent ID: 8385202

Claim:
A method, comprising: migrating (i) a virtual machine (VM) and (ii) quality of service (QoS) policy, from a first physical server, to a second physical server distinct from the first physical server, wherein the QoS policy corresponds to a virtual network switch associated with the migrated VM; upon determining that a conflict exists between the migrated QoS policy and a second QoS policy on the second physical server, adapting the migrated QoS policy, comprising: determining at least one hardware characteristic of the second physical server; determining at least one configuration characteristic of the migrated VM; and altering the migrated QoS policy to resolve the conflict, based on the at least one hardware characteristic of the second physical server and the at least one configuration characteristic of the migrated VM; passing a data flow through the virtual network switch associated with the migrated VM on the second physical server; and selectively controlling the virtual network switch on the second physical server to control the data flow based on the altered QoS policy.
