[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 Bcast:192.168.1.255 Mask: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 Mask: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.

Do you have any idea what is causing this? 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.
Thanks for any insight,

Yes. 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.

When I run " network-bridge start ", the xenbr0 interface is
created,
brctl shows the bridge is created with two interfaces inside. But, network
doesn''t work. It seems that I can receive packets but not send.
Syslog shows:

Do you have any idea what is causing this? 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.
Thanks for any insight,
Best regards,
Emre

Re: AW: [Xen-users] Gutsy Xen 3.1 2.6.22-9-xen network-bridge problem
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!
Kind regards,
Bart Verwilst

Yes. 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.

Hi Hinrich,
So do you think it''s because of this checksum offloading? 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?
Thanks for your interest and Best regards,

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:

Re: AW: [Xen-users] Gutsy Xen 3.1 2.6.22-9-xen network-bridge problem
Hi, I can confirm that disabling tx offloading fixes the problem! For gutsy ( in our case ), just add the following line at the bottom of your /etc/network/interfaces file: up ethtool -K eth0 tx off repeat for every interface ( i only have 1 :) ) Thanks a lot guys!
