similar to: xen 3.2 with bridge, domU cannot connect to the internet

Hi, I would like to ask concerning problems after installing xen 3.3 on Centos 5.2 I use 2.6.18.8-xen (xen3.3.1 testing - installing with mercurial). After done with make world and make install, I did mkinitrd and placing it in /boot changing the grub and reboot.. succeded I do not install libvirt and the domUs from the previous xen 3.0 (built-in Centos 5.2) are NOT able to start : [root@wing

Situation peth0 = internet peth1 = local private network Dom0 is only configured to use peth1 and works fine as such I have a DomU setup as a NAT box for the local network to the internet and it is functioning as well. DomU is also running a caching DNS and DHCP for the local network The problem I have is DomO''s gateway is set to the local network IP of the DomU, as is

Hi list! I''m trying to figure out a way to use network configuration scripts provided by the distribution to manage network/bridge configuration with xen.. This means I dont''t want use xen "network-bridge" (or any other) script at all, because they are a bit limited in functionality. I want to setup VLAN interfaces with the scripts/tools provided by the

Hi *.*, This is a continuation on the 2 NICs thread after some more testing. Just to remember my goal. --------------------------- I want to create a domU with 2 virtual NICS. One of them will contact the outside world, the other one will contact a VPN. No reason in concrete for choosing the bridging protocol, only because its the default one. I installed the dom0 with the 2 NICs active, with

Hello everyone. I just installed Xen 3.0.3 in a debian etch box. Linux server1.example.com 2.6.18-6-xen-686 #1 This server1 has two real nic (eth0 with real MAC 00:13:72:57:7B:AE and eth1 with real MAC00:13:72:57:7B:AF). I made a network-bridge custom like this: ----------------------------------------------------------------------- #!/bin/bash dir=$(dirname "$0")

Hi, XEN confused me very much. In the config file I had: vif = [ ''mac=00:16:3e:ff:3b:18,bridge=xenbr0'', ''mac=00:16:3e:c0:92:08,bridge=xenbr1'' ] The idea was to connect eth0(peth0) via xenbr0 to DomU''s eth0, and eth1(peth1) via xenbr1 to DomU''s eth1. However it turned out that the first address is assigned to "eth2" in DomU,

Hi, I found this mail about network problems in the archive. I think I have the same network problems with a routing (with or without NAT) domU connected by two network bridges. The dom0 logs thousands of following messages: -- Attempting to checksum a non-TCP/UDP packet, dropping a protocol 1 packet -- and all outgoing TCP packets have wrong TCP checksums (traced on another machine on the

Hi, I have some problems with my OpenVPN server in a Xen DomU. OpenVPN works fantastic but theres a problem connecting other DomUs on this server. I have the following iptable rule to forward the requests to the internet. iptables -t nat -A POSTROUTING -s 10.8.0.0/24 -j MASQUERADE This works fine. I can connect to other DomUs on the same server but they can''t answer the

Hallo, I have running xen-4.2/linux-3.8 (compiled) on any hosts. - dell pe r720: drac, eth0-3:igb squeeze -> boot_xen:ok net:ok bridge:ok - dell pe R620: drac=eth0, eth1-3:tg3 wheezy -> boot_xen:ok net:ok bridge:fail So i running "xend start" (or "xenbridges start") on my patient (R620 with broadcom tg3) network will be lost: RTNETLINK answers: File exists

If you get a lot of those messages and you don''t want them: peth1: received packet with own address as source address or peth0: received packet with own address as source address This is the way I found to solve this problem on Debian maybe someone can post more information about other distribution like suse or redhat... This problem will occur if you have more than one dom0 on your

Hi there, i have now a working domU which is bridged into the dom0. I have set as gateway the bridge device. So far this works i can access the domU from the dom0 (for example using ssh or http). The access from domU into dom0 works, too. But i can not get a working NAT setup to route the traffic from domU into the internet. I tried a few variants, switching of tx checks on the ethernet device,

Hi, I just installed Xen in Ubuntu Hardy. DomU is not accessible either from Dom0 or external network. I used default set up network-bridge/vif-bridge from xend-conf.sxp. Bridge has got default name eth1 which is my default ethernet interface. Before creating DomU: root@jaguar-0:/home/longina# xm list Name ID Mem VCPUs State Time(s) Domain-0

Hi, I have 3 xen box with 2-3 VM on each. Each server has 2 nic (1 for external and 1 for internal network). All VMs are webserver and they mount a nfs filesystem. I''ve noticed that on each dom0 there are many dropped packets. Server config is: 1- DELL (2xQuad Xeon E5320 @1.86Ghz - 8Gb Ram - Perc5 - Kernel 2.6.18-6 (debian etch)) 2- DELL (2xDual Xeon 5110 @1.60Ghz - 4Gb Ram - Perc5 -

> That''s great, except when you need *two* bridges, for two > independent subnets, and there is no, as far as I can see, peth1. You can have multiple vethX interfaces on recent builds -- see netback/loopback.c. I think the current default is a rather miserly 1 (and should be increased), but can be set on the command line.

I have a OpenSuse 10.3 with xen 3.1.0 running and it''s been running fine for a few months. This past weekend it suddenly started to act up and after some troubleshooting I can now say that it seems like the guests(domU) loose the outgoing network pipe, from the console I can see that the TX counter is stuck at the same value but it''s no errors. It behaves as if whatever I try to

Hello Everyone, I have set up a xen server with 10 physical network devices using the bridge mode of XEN. This is because I want to split and separate the network traffic for security reasons. Maybe the best way is to use pci back hide. But I want to understand what is going on here. For all testings I have only activated eth[0-3]. My first tests were successful. I have created a VM using

Hi Folks: I have a strange problem with multiple (2) NICs on a CentOS 5.5 dom0 setup running xen 3.4.3 and have been struggling to fix it for some time. I could not find anything by googling or searching through this list but that is probably because I couldn''t figure out the correct search terms. After I configure my bridges the command "system network restart" fails for eth1
