Hi, This post really made my day, as i'm having the same problem myself. Thanks for writing out the problem so clearly! I'm using the same kernel, and have been looking for an answer since yesterday myself. Could you please let us know whether the ethtool trick works? I'll try it as well as soon as i'm home in an hour or so, and let you guys know of the outcome! Thanks!

I thought that's in the link? Whatever, use that command ethtool - K eth0 tx off on your interfaces (on dom0). I don't know if that is necessary, but I use it on every interface / bridges. You can put that command into the xen networking scripts. Don't know exactly where. Hinrich _____ Von: Emre Erenoglu [mailto:erenoglu@xxxxxxxxx] Gesendet: Freitag, 17.

What shall I do to get rid of it? Couldn't understand from the message... would "ethtool - K eth0 tx off" be the right command?

August 2007 12:11 An: xen-users@xxxxxxxxxxxxxxxxxxx Betreff: [Xen-users] Gutsy Xen 3.1 2.6.22-9-xen network-bridge problem Hi, I have a strange problem with my networking setup. I read all forums around the world where people had similar problems, but couldn't find a solution. I have an Attansic L1 gigeth chip on my mainboard. This chip works OK in stock Ubuntu Gutsy (development) 2.6.22-9-generic kernel. When I boot into Xen, and after the bridge is created, the network stops working. Some info: - If I do " /etc/xen/scripts/network-bridge stop " then the network comes back... - I can ping sites, but can never "communicate" with them. For example, I can "telnet" to 22th port of an sshd server, receive the "welcome to xyz sshd server etc." but can never send any command. Same for telnet/http/ftp connections. The system also cannot resolve DNS names, but can still ping. Same thing happens inside the DomUs. - My /etc/xen/xend-config.sxp has " (network-script network-bridge) " and " (vif-script vif-bridge) " directives. ifconfig -a output: eth0 Link encap:Ethernet HWaddr 00:18:F3:9D:6E:FC inet addr: 192.168.1.2 <http://192.168.1.2/> Bcast:192.168.1.255 <http://192.168.1.255/> Mask: 255.255.255.0 <http://255.255.255.0/> inet6 addr: fe80::218:f3ff:fe9d:6efc/64 Scope:Link UP BROADCAST RUNNING MTU:1500 Metric:1 RX packets:17016 errors:0 dropped:0 overruns:0 frame:0 TX packets:20307 errors:0 dropped:0 overruns:0 carrier:1 collisions:0 txqueuelen:1000 RX bytes:6377107 (6.0 MB) TX bytes:9225065 (8.7 MB) lo Link encap:Local Loopback inet addr: 127.0.0.1 <http://127.0.0.1/> Mask:255.0.0.0 <http://255.0.0.0/> inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:636 errors:0 dropped:0 overruns:0 frame:0 TX packets:636 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:11732 (11.4 KB) TX bytes:11732 ( 11.4 KB) veth0 Link encap:Ethernet HWaddr FE:FF:FF:FF:FF:FF BROADCAST NOARP MULTICAST MTU:1500 Metric:1 RX packets:18 errors:0 dropped:0 overruns:0 frame:0 TX packets:38 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:3614 (3.5 KB) TX bytes:18219 (17.7 KB) veth1 Link encap:Ethernet HWaddr 00:00:00:00:00:00 BROADCAST MULTICAST MTU:1500 Metric:1 RX packets:0 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:0 (0.0 b) TX bytes:0 (0.0 b) veth2 Link encap:Ethernet HWaddr 00:00:00:00:00:00 BROADCAST MULTICAST MTU:1500 Metric:1 RX packets:0 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:0 (0.0 b) TX bytes:0 (0.0 b) veth3 Link encap:Ethernet HWaddr 00:00:00:00:00:00 BROADCAST MULTICAST MTU:1500 Metric:1 RX packets:0 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:0 (0.0 b) TX bytes:0 (0.0 b) vif0.0 Link encap:Ethernet HWaddr FE:FF:FF:FF:FF:FF BROADCAST NOARP MTU:1500 Metric:1 RX packets:38 errors:0 dropped:0 overruns:0 frame:0 TX packets:19 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:18219 (17.7 KB) TX bytes:3684 (3.5 KB) vif0.1 Link encap:Ethernet HWaddr FE:FF:FF:FF:FF:FF BROADCAST MULTICAST MTU:1500 Metric:1 RX packets:0 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:0 (0.0 b) TX bytes:0 (0.0 b) vif0.2 Link encap:Ethernet HWaddr FE:FF:FF:FF:FF:FF BROADCAST MULTICAST MTU:1500 Metric:1 RX packets:0 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:0 (0.0 b) TX bytes:0 (0.0 b) vif0.3 Link encap:Ethernet HWaddr FE:FF:FF:FF:FF:FF BROADCAST MULTICAST MTU:1500 Metric:1 RX packets:0 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:0 (0.0 b) TX bytes:0 (0.0 b) When I run " network-bridge start ", the xenbr0 interface is created, brctl shows the bridge is created with two interfaces inside.

I can give more information if requested. (can't issue the network-bridge start command now as it will disconnect me from the machine if I do so, I'm remotely connected at the moment) P.S. I tried also with a USB ethernet card, same result.
