What do I need to change to get peth0 using a different mac address? I was hopeful I could figure it out but no joy :-( Regards, Ted _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel
> What do I need to change to get peth0 using a different mac address?Why do you need to set peth0''s MAC address? It shouldn''t be endpoint src or destination of any packets. If you need to change it: "ifconfig peth0 hw ether xx:xx:xx:xx:xx:xx" Ian _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

Was something changed recently that would affect this? I was seeing the identical behavior on both my SMP and UP machines until today. Got to the point where I was using bgp to route local host traffic through my gateway to get the two dom0 peth0''s tp talk to each other. dom0-1 - 10 domU dom0-2 - 3 domU Gateway | -------------------------- subnet A | | dom0-1 dom0-2 |peth0 |peth0 subnet B ---------------------------------------------------- | | | | | | | | | | | | | 1-1 1-2 1-3 1-4 1-5 1-6 1-7 1-8 1-9 1-10 2-1 2-2 2-3 With this topology dom0-1 and dom0-2 where seeing the peth0 mac address in the arp table, so one peth0 could not talk to other across subnet B.

Have you given your peth0 an IP address? it shouldn''t need one. It should be configured with ''-arp''.

The interface in question is using an e1000 module, all default settings. To be honest I really thought this was normal as I kept saying to myself how could no one else be having this problem. Anyway, If I see this again you can be assured of an extensive detailed bug report :-) I really have to say, that the work you guys are doing is making my life easier and easier every day :-) Thanks to the "Xen Team" for such a killer contribution.
