[Xen-users] "received packet with own address as source address"
Hello again, folks! I''m getting one strange problem with FC5 running on XEN 3.0.3 x64... The MRTG point to my machine with XEN running one absurd volume of output data sent (normal is around 6 MB/s) and when XEN is working we get 80 MB/s until my DRAC is alive... after this, the machine crash, DRAC stop do reply, swith stop do work together... Anyone knows whats happening now? ;) Thanks again! _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Re: [Xen-users] "received packet with own address as source address"
Can you post a copy of your bridge config? Looks like you have a bridge porting multiple nics and something went wrong. Is STP enabled on any bridges?

Re: [Xen-users] "received packet with own address as source address"
Hello Tiago, one more brazilian guy around here ;) I''m just having a quick look on the list messages, since today I''m a bit out of time, just maybe this helps you .. I got that message when my xenbr0/peth0 (yes, the real eth0, renamed by xend scripts) interfaces (or whatever bridge name you are using) have a MAC address configured in it. I don''t know rh-style configs, but on command line : ip link set xenbr0 down ip link set xenbr0 addr fe:ff:ff:ff:ff:ff ip link set xenbr0 up same with peth0 ip link set peth0 down ip link set peth0 addr fe:ff:ff:ff:ff:ff ip link set peth0 up just don''t forget to write down the mac address of your peth0 (ip link show peth0) before setting it to the broadcast one and put it in your dom0 eth0 (ip link set eth0 down; ip link set eth0 addr <your_mac_addr>; ip link peth0 up). If it works, as homework you look how to do this in the normal network boot scripts ;) Ate mais ;) []''s should solve the problem On Fri, 2006-10-27 at 18:47 -0300, Tiago Cruz wrote:> Hello again, folks! > > I''m getting one strange problem with FC5 running on XEN 3.0.3 x64... > > The MRTG point to my machine with XEN running one absurd volume of > output data sent (normal is around 6 MB/s) and when XEN is working we > get 80 MB/s until my DRAC is alive... after this, the machine crash, > DRAC stop do reply, swith stop do work together... > > Anyone knows whats happening now? ;) > > Thanks again! > > > _______________________________________________ > Xen-users mailing list > Xen-users@lists.xensource.com > http://lists.xensource.com/xen-users >_______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Re: [Xen-users] "received packet with own address as source address"
Hi Tiago, well ... as I said before .. I wouldn''t set your eth0 mac address (on dom0 ) to the broadcast one ... Before setting the one on peth0, write it down and set eth0 (of your Dom0, not the DomU''s) to it. That can be done easily on the init scripts (sorry, I use debian, so the network scripts are completely different) :) But the peth0 and xenbr0 mac addresses should be fe:ff:ff:ff:ff:ff =) []''s Theo Diem On Mon, 2006-10-30 at 12:37 -0300, Tiago Cruz wrote:> Hello Theo, many thanks for your help! ;) > > On Mon, 2006-10-30 at 13:59 +0100, Theo Cabrerizo Diem wrote: > > > I got that message when my xenbr0/peth0 (yes, the real eth0, renamed by > > xend scripts) interfaces (or whatever bridge name you are using) have a > > MAC address configured in it. > > Well, I don''t know exactly what''s happen but I''ve configured only my > eth0 on boot time, and put this on my rc.local: > > ip link set peth0 down > ip link set peth0 mac fe:ff:ff:ff:ff:ff > ip link set peth0 up > > ip link set xenbr0 down > ip link set xenbr0 mac fe:ff:ff:ff:ff:ff > ip link set xenbr0 up > > ip link set eth0 down > ip link set eth0 mac fe:ff:ff:ff:ff:ff arp off > ip link set eth0 up > > > Now, after boot my machine don''t crash any more, but the bridge stay > without IP/MAC: > > xenbr0 Link encap:Ethernet HWaddr FE:FF:FF:FF:FF:FF > inet6 addr: fe80::fcff:ffff:feff:ffff/64 Scope:Link > UP BROADCAST RUNNING NOARP MTU:1500 Metric:1 > RX packets:159 errors:0 dropped:0 overruns:0 frame:0 > TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 > collisions:0 txqueuelen:0 > RX bytes:14472 (14.1 KiB) TX bytes:0 (0.0 b) > > [root@xen ~]# brctl show > bridge name bridge id STP enabled interfaces > xenbr0 8000.feffffffffff no peth0 > vif0.0 > > Anyway, look that is all working now :) > Many thanks! > > - Tiago Cruz >_______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Re: [Xen-users] "received packet with own address as source address"
Crap ctrl+enter .... :-P .. sorry everyone about the half message ... So I''m going to finish it inline. Btw, The bridge shouldn''t have an IP or mac address .. after all it''s a bridge (IMHO). If you need an interface between dom0 and one bridge ... : ''modprobe nloopback'' on dom0 (which is loaded by default on xend) you will have 8 veth interfaces (veth0-7, the veth0 is renamed to eth0 by xend scripts) and 8 vif interfaces (vif0.0 - vif0.7). you could add vif0.0 to your bridge and set the ip/mac on eth0 (which is what xend does). If you need more bridges or interfaces on your dom0, use the remaining vif''s and veth''s :D Yes, my box worked a bit by putting an ip on xenbr0, but it turned a bit unstable .. after a couple of domU''s a kernel panic happened. (and that could be repeated as many times as you whished. so wasn''t a random bug) After reading carefully the bridge-network script and vif-bridge, I understood what xend does at boot time and could understand much better xen networking :D []''s Theo On Mon, 2006-10-30 at 16:48 +0100, Theo Cabrerizo Diem wrote:> Hi Tiago, > > well ... as I said before ..

I also see this problem when using bonding (round robin) connected to the bridge, but only broadcasts (ARP requests?) seem to trigger such a message. If anybody can tell me the right filter expression for tcpdump, I could show an example here.
