Hello, Just did a fresh install of xen-4.0 and using the 2.6.31.13 dom0 kernel. I have 6 linux debian guests running, and on my host console i am getting these errors rolling pretty constantly. "Attempting to checksum a non-TCP/UDP packet, dropping a protocol 1 packet" I tried doing the ethtool -K eth0 tx off and same thing on peth0, using bridged mode for network config. Any tips?

Hi All. I have currently a small problem to solve.

I think that rx buffer is to small (no strange messagess in dmesg) and would

Hi, I have problem with a Centos 5.3 computer. The networking is very slow. The networking card is a RealTek 1GigE. I plugged an Ubuntu laptop on the same cable and port with an Intel GigE, and it's about 8 to 10 times faster. So the problem is likely to be with the CentOS config. Any suggestion on how to track down the problem with speed. I have checked the packets with wireshark, no

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

Hello Because I did not send , and then retransmitted. I am using the CentOS5.7. In a state where the link down, I did a ping to the IPv4 and IPv6. IPv4 succeeds in ping. but, IPv6 is ping fails. Once confirmed by ifconfig, it did not have a Link-Local Address. At link down, Is the Link-Local Address not set? Leave the link down, Is there a way to avoid this? # ethtool eth1 Settings for eth1: ?

Last problem I had involved changing one character in my configuration scripts. Really easy once someone showed me what was wrong. Well I think this issue is just the same. The moment I used apt to install the Xen kernal and tools I lost internet connectivity. I have been managing because I can restore connectivity be deleting the bridge mpower@dodtsair:~$ sudo ifdown eth0

Hi List, I am running a x86_64 Centos server, after a reboot the network has decided to not work.. this particular machine has 8 eth ports eth0-7. eth0 and eth3 were bonded (mode 1 ) after reboot the bond did not work. It came up OK but no data was passing through it. all other interfaces on the machine were working. I decided to remove the bond, so after removing the bond i was left with eth0

Hi all, I have been having an issue for over a year with several Xen installations and have not been able to find out if this is just something I am missing. Basically I am trying to configure a firewall with two ethernet cards in a domU using pci passthrough. I am hiding the Ethernet cards at boot time via the pciback.hide kernel option. Right now I am running Xen 3.3.0 and the two Ethernet

We have an HP DL360 server with dual on-board Tigon3 ethernet cards. We are using eth0, eth1 is unused at the moment. Sometimes when the network interface is under heavy load, for example moving large file transfers over rsync or NFS, the network interface stops working and we lose all connection to the server. The only solution at this point is to jump on the console and restart the network

I am having an extremely strange issue with a BL460c1 (G1) blade on a c7000 enclosure. I could not for the life of me get the machine to ping the gateway or any other blade on the same enclosure (yes, the subnet mask was correct & quadruple-checked); although pinging to the local IP works. I was almost convinced that it was a network or hardware issue; until I asked someone to try
