A computer implemented method, computer product code, and data processing system are provided for transferring data between virtual partitions. A request is received to transfer a packet from a first partition to a second partition. A free buffer is identified from a buffer pool of the second partition, and a receive descriptor is written. A bit within the receive descriptor is set to identify a receive descriptor ring of second partition. A first interrupt is generated to the second partition. The packet is then copied to the free buffer, and the receive descriptor is updated.
