[Xen-users] URGEND!!! Problems Bonding
Hey, I installed Xen 3 on my machine. I copy the .config and did a make ARCH=xen oldconfig Then a make ande an ./install.sh My machine is booting, but my bonding device is not known.. Can u help me?

I think Xen-3.0 is not really bonding aware at the current state of development. Here''s what Greg Brackley <greg.brackley-sender-8aba35@lucidsolutions.co.nz> said on Xen-devel on this topic: [...] I believe it is possible to use bonding with Xen. I have one machine running successfully with 802.3ad bonding. I have had a few problems with the networking, but I have overcome most of them. I was trying to use the bonding support in conjunction with VLAN support. I still have concerns that there are some outstanding issues with checksum offload support in the Xen network drivers. To get the xenU networking operating I found I needed to disable checksum offload support (ethtool -k eth0 tx off). There doesn''t appear to be any such ethtool support in the xen0 loopback driver. I also dug around a little in the kernel code to look at the checksum offload options[1][2], and was unclear as to why a loopback style device like the xen loopback driver was declaring that it was capable of TCP/UDP IPv4 checksum offload. It might explain why I could get ICMP working but not UDP/TCP (Note sure how/if this relates to similar IPsec issues). I would be very keen to get clarification on this (please?). I think there might also be some interaction with the NIC driver. My tg3 based machine works ''out of the box'', whereas the e1000 solution requires the checksum offload disabled in the Xen driver. I was also using a non-GPL sk98lin based sk-9e22 card which was having problems, but I plan to use the newer sky2 driver when I get time. You didn''t mention what problems you were having? Whether it worked without xen, etc. What does /proc/net/bonding/* say? I have been disabling the xen network script (and not doing the interface renaming etc), and using the FC4 init scripts to bring up my xen0 networking. I needed to tweak the xen0 hotplug. Other than the problems discussed above I have managed to get the networking going. I would like to resolve the checksim offload, but have had time to look into it. [...] I also failed to setup bonding on the XenU. First it looked quite optimistic, the /proc/net/bonding/bond0 file looked correct, but the traffic was still routed over only one interface.
