sorry it was not
$ sudo ethtool -K eth0 tx off
$ Cannot set device tx csum settings: Operation not permitted

that error was because i didn't use  sudo
but after using sudo it was
$ sudo ethtool -K eth0 tx off
$ Cannot set device tx csum settings: Operation not supported

maybe eth0 is the bridge device?

The network-manager package was making some issues. You may try removing it and configuring your network by hand using /etc/network/interfaces

Re: Re: xen networking in ubuntu gutsy

bharath venk
Hi Emre,
i removed network package and tried .. but the same results .... can u be more descriptive what should be done ..

i actually got network in domu  working once .. i had placed "up ethtool -K eth0 tx off " in /etc/network/interface  that time network used to not start while booting there would be a cross mark at the network manager applet at desktop .. but only after i change /etc/network/interface  by simply adding a space in it ... automatically network manager is to start the network .. and then network started working in domu ...

but after  i updated the kernel for some reason ... and removed the previous kernel ..  network manager started the network while booting only ...  so i did
"/etc/init.d/networking restart" with "up ethtool -K eth0 tx off " placed in /etc/network/interface it gave me operation not supported ....
now i reinstalled the previous kernel but it is now showing the same result as the updated kernel 

can any one pls help in solving this issue as it is very important .. i have to set up several virtual machines at work .. n with out network it is all most useless

Hi,

I used to have such problems with the ethernet card that I had to use with 2.6.19 kernel (atl1 driver). However, in recent kernels the problem was resolved and the driver was running without any need for ethtool modifications.

I also had trouble setting up the xen bridge due to network-manager package, thus I removed this package and configured network interfaces by hand myself.

Also you need to make sure that the interface you are trying to run the ethtool command is a "real" interface, not the one that Xen bridge is created. Real interface might have been renamed to "peth0" after Xen bridge script runs. You can also check that.

Re: Re: xen networking in ubuntu gutsy

Well, my comment was for "atl1" driver only. Which is "Attansic L1 chipset". I don't know if you had the same chip ethernet card.

Note that all ubuntu kernels I tried with Xen had a lot of issues. Hardy's 2.6.24 kernel is I guess better, but I kinda switched to KVM.
