Exactly the same place I draw it for a discrete machine: if I have two or more hosts and my operating system supports a protocol, I should be able to hand the network hardware a fully formed layer 2 frame and expect it to be transmitted to the other hosts on that virtual network as supplied. If there are other systems on the same "wire" that don't understand that protocol, they should ignore it, just as real machines do. I shouldn't have to care if IBM has gotten around to writing special code to allow that protocol to work -- CP should move the packets to the virtual interfaces and let the hosts decide what to do with them.
Guest LANs should be protocol transparent. Let the hosts attached to the LAN decide what they can cope with; the LAN transport infrastructure shouldn't know or care what is inside the frames. That's up to the hosts -- CP should be concerned with infrastructure, not content. -- db David Boyes Sine Nomine Associates > -----Original Message----- > From: Linux on 390 Port [mailto:[EMAIL PROTECTED] Behalf Of > Alan Schilla > Sent: Friday, March 14, 2003 3:30 PM > To: [EMAIL PROTECTED] > Subject: Re: QDIO for virtual NIC > > > Is IPv6 a standard protocol?
