Abstract
A system, method, and computer program product are provided for performing fast migration of a virtual resource from one node to another node. The method includes the steps of receiving a first request to migrate a resource from a first node to a second node, transmitting a second request to the second node to create a new instance of the resource, collecting a set of changes associated with the resource in a data structure, and transmitting the data structure that includes the set of changes to the second node. The second node generates the new instance of the resource based on a snapshot of the resource captured by the first node at a previous point in time and updates the new instance of the resource based on the set of changes such that the new instance of the resource on the second node matches the resource on the first node.
