1. A method for supporting virtual machine live migration in a subnet, comprising:
providing, at a computer including one or more microprocessors, a subnet, the subnet comprising:
a plurality of switches;
a plurality of host channel adapters, the plurality of host channel adapters being interconnected via the plurality of switches, and
a virtual machine, the virtual machine being attached to a host channel adapter of the plurality of host channel adapters, the virtual machine comprising a virtual switch;
wherein each of the host channel adapters are arranged with an architecture comprising one of a virtual switch with prepopulated LID (local identifier) architecture or a virtual switch with dynamic LID assignment architecture;
upon a migration of the virtual machine within the subnet, updating a path record for the virtual machine within the subnet by sending, from a management entity, at most, two management packets to each of the plurality of switches.
