Abstract
A system and method can support virtual machine live migration in a network. A fabric adaptor can be associated with a plurality of virtual host channel adapters (vHCAs), and wherein each said virtual host channel adapter (vHCA) is associated with a separate queue pair (QP) space. At least one virtual machine operates to perform a live migration from a first host to a second host, wherein said at least one virtual machine is attached with a said virtual host channel adapter (vHCA) that is associated with a queue pair (QP) in a said queue pair (QP) space, and wherein said queue pair (QP) operates to signal a peer QP about the live migration and provide said peer QP with address information after migration.
