1. A method of establishing one or more connections between a target host machine and a remote endpoint connected to a virtual machine (VM) running on a source host machine, comprising:

  • receiving, by a target hypervisor executable on a target host machine, a list of one or more remote endpoints to which a VM executable on a source host machine is connected, the source and target host machines being coupled to an InfiniBand network, and the source host machine and target host machine being remote from the remote endpoint; and

    establishing, by a host communication manager executable on the target host machine, a network connection to one or more of the remote endpoints specified in the list before the VM has completed migration from the source host machine to the target host machine, wherein the target host machine includes a first host channel adapter (HCA) including a first queue pair associated with the VM, wherein before the VM has completed migration to the target host machine, the target hypervisor receives the list and the first queue pair is connected to a remote queue pair included in a remote endpoint specified in the list, and wherein the target host machine connects to an InfiniBand fabric of the InfiniBand network via the first HCA.
