I really think Qemu shouldn't be moving this kind of data over in a migration. I think that having the VF do a suspend/resume is the best way to go. Then it simplifies things as all you have to deal with is the dirty page tracking for the Rx DMA and you should be able to do this without making things too difficult. - Alex -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
