AW: [Xen-users] Gutsy Xen 3.1 2.6.22-9-xen network-bridge problem
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.

Betreff: Re: [Xen-users] Gutsy Xen
3.1 2.6.22-9-xen network-bridge problem
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,
On 8/17/07, Hinrich

this might help (hopefully)
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.

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.

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.
