I don't know of any zero-copy through the hypervisor mechanisms for serial ports, but I know we do that with the various virtualization network devices. > Do you have another recommendation? I don't have to make alternative recommendations until you can show that what we have can't solve the problem acceptably, and TCP emphatically can. _______________________________________________ Virtualization mailing list Virtualization@lists.linux-foundation.org https://lists.linux-foundation.org/mailman/listinfo/virtualization
