It depends on your networking setup but usually inter-guest packets do not go through a physical NIC. For special use cases there is also the ivshmem device which allows multiple guests to access a piece of shared memory on the host. You would need to customize your applications to make use of this. See docs/specs/ivshmem_device_spec.txt.
