My domains dont see any traffic until you try to connect out from within the domain. Tried this several times and it was consistent. I have no firewall either. running each domain on different cpu probably doesn''t help, although Im no network expert.

Hello, Presently I am running CentOS release 5.5 (Final). I am looking to setup bridging as I would like to setup some KVM virtual hosts on my system as a test lab. I am following the the instruction at this site > http://tldp.org/HOWTO/BRIDGE-STP-HOWTO/index.html but I cannot figure out where I am going wrong and would be thankful if someone could point me in the right direction.

I''ve setup Xen 3.0.2-2 (binary install) on Ubuntu 6.06, got my domUs up and running, got them connected to the Internet but I can''t even ping to any of these VMs. Now I''m not linux/xen genious but could the problem be that xen-br0 doesn''t have an IPv4 address? (it''s got an IPv6 address) Since I don''t use IPv6 on my network this seems a

Hi list, I''m looking for some help in getting my domU network aware. Currently I can run /etc/xen/scripts/network from dom0 to successfully create xen-br0. After I do this, dom0 can still access any network resource that it could before. However, when I start up a domU, it can only ping dom0; it fails to connect to any other ip. I don''t receive any sort of error message,

Hi, I've set up a bridge using the 2.6.11.6 kernel. The machine is running Debian testing with three NICs in it. eth0 is a standard 100Mb Intel NIC, eth1 and eth2 are both Intel gigabit cards using the e1000 driver. I tested everything at 100Mb and it worked fine. I moved the machine into production, eth1 plugging into a dumb 100Mb D-link switch, eth2 plugging into a shiney new Cisco

Hi, I tried this post on the Xen list first with no answer. I have 4 machines and 3 of which (all different) have no network access when booted into Xen. I tried using Fedora Core 8 and it produced the same results. Is it normal for the virbr0 interface to take an arbitrary IP? How does it decide what to use? An ifconfig when booted into Xen shows the following: eth0 Link encap:Ethernet

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 all, Has anyone seen this before? I''m running a CentOS 5.3 with xen 3.0 and the server has been running fine for a long time. In fact, it was up for 186 days before I had to reboot after the "network died", and I couldn''t fix it. The server has multiple domU''s on it, which all still works when the host node (dom0)''s network dies with these

I just did a fresh install of centos 5.0 from cd, followed by yum update which installed 399 packages. No failures or errors that I can see. I have three nics in the box, but am only setting up one at the moment. The box can ping others in my network, but if I try ssh, telnet, ftp, etc I get this: [root at cm network-scripts]# ftp watchdog ftp: connect: No route to host ftp> [root at cm

Moi! I upgraded Xen-2.0.1 to Xen-2.0.5 (testing) and everything compiled cleanly. I''m still able to boot dom0 and start domUs but networking doesn''t work anymore. xen-br0 appears in dom0, but vif-interfaces now only when ifconfig -a is used. Interface appears in domU and all seems to be fine, except no any data doesn''t move in any direction. I can''t even ping

Hello, I am facing some problems in bridged networking. I have successfully created a bridge br0 and added a virtual machine to it. Now the address of virtual machine is 10.1.3.31.
