Abstract

System and method for supporting virtual machine migration in a high performance computing environment. In accordance with an embodiment, when a virtual machine migrates from a first subnet to a second subnet, a gateway port at the first subnet can, upon receiving packets addressed to the migrated virtual machine, consult a memory lookup table to discover the virtual machine's new addresses. The gateway port can update the packet accordingly. The memory lookup table can be addressed based on a GUID of the virtual machine.
