    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.

    Abstract: A system and method can provide fault tolerance in a middleware machine environment. A subnet manager can determine whether there is a path record change when a fault occurs in the middleware machine environment. Furthermore, the subnet manager can signal a dynamic reconfiguration event to at least one host in the middleware machine environment. The at least one host can send a message to the subnet manager to query for a latest path record. Then, the subnet manager can provide a latest path record to the at least one host.

    Abstract: A system and method can support virtual machine live migration in a network. A virtual switch can be associated with a plurality of virtual functions (VFs), and wherein each said virtual function (VF) is associated with a separate virtual interface (VI) space. At least one virtual machine that is attached with a said virtual function (VF) can be associated with a virtual interface (VI), e.g. a queue pair (QP) in an Infiniband (IB) architecture. Furthermore, said at least one virtual machine operates to perform a live migration from a first host to a second host with said virtual function (VF) attached.
