similar to: Xen with NAT networking.

Hi, I have taken the long and winding road and indeed it lead me to your door. I need your help, please. My Xen includes 2 guests. Xen itself (10.2.0.52) gets free access to the outside world and to its guests. Both guests however (10.2.0.54/10.2.0.55) see each other but stay under house arrest! Not a single ping manages to go past the bridge (xenbr0) and get an answer from the default gateway

I have fedora13 as domain0 kernel on xen-3.4.3 or xen-4.0.1. I installed ubuntu10.04 as guest-os following this : 1) download installer from : - http://fi.archive.ubuntu.com/ubuntu/dists/lucid/main/installer-amd64/current/images/netboot/xen/vmlinuz - http://fi.archive.ubuntu.com/ubuntu/dists/lucid/main/installer-amd64/current/images/netboot/xen/initrd.gz to /boot directory 2) edit xen guest

Hi, I''m trying to set up networking on a new machine. I''m not getting any networking from the domU''s I notice that I have two bridges being created: xenbr0 Link encap:Ethernet HWaddr FE:FF:FF:FF:FF:FF inet6 addr: fe80::200:ff:fe00:0/64 Scope:Link UP BROADCAST RUNNING NOARP MTU:1500 Metric:1 RX packets:3024 errors:0 dropped:0

Hi, I have Xen 3.0.3 installed on CentOS 5.5 with 2 paravirtualized domU''s configured to use the default bridge networking and am having networking issues. If I boot the computer fresh I am able to ping dom0 and can SSH into it and start the domU''s. The following ping snippet demonstrates the problem. The first group of "Destination Host Unreachable" is while the

I am running Xen 4.0.1 with a 2.6.18-194.32.1.el5xen CentOS Dom0. I built and installed the Xen binaries from source. The systems boot successfully however I am having issues bring up DomUs.

Hello, Are there any good alternatives to the network-nat script on Debian Squeeze? I have tried using (network-script network-nat) and (vif-script vif-nat), but I end up with an error message like Error: Device 1 (vif) could not be connected. ip addr add 10.0.1.259 dev vif4.1 failed with configuration file directive vif =[ ''script=vif-nat,ip=10.0.1.132'' ] I need Internet

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, until now, i have been using Xen 3.0.2. Now i upgraded to Xen 3.0.4. Can anybody confirm, that the ordner in the config files for the network interfaces has not changed? My config file used to read: vif = [ ''bridge=xenbr0'', ''bridge=xenbr1'' ] So inside the DomU, eth0 was attached to xenbr0 on the host and eth1 was attached to xenbr1. Now i upgraded to

Hi, I have a new xen hosting platform. I have given the bridge a static IP which I can ping/ssh to etc, when I create a new vm all works well apart from the networking. If I give DomU a static IP I can''t ping out from the box, Dom0 can''t ping the vm. I''m suspecting it just isn''t seeing the bridge but am unsure where to start looking. This is a very standard

Hello, I have a Gentoo Linux guest, which was working very well with the past xm tool stack. Since the migration to xen-4.1.1 and to the new xl tool stack, I have a problem for the IP assignation. Actually, when dhcpcd starts at boot time the IP address is not correctly assigned. This also happens if I perform "dhcpcd eth0" once I''ve accessed to the guest shell. I

I have a SOHO server (Debian testing) that I''m using for several purposes so I''ve set up a Xen

Hey, I was originally asking questions on xen-users but no one seems to have any idea about this so I figured I''d try this list. I compiled Xen from source (3.2 testing) on an Intel machine running Fedora Core 8 and have discovered that my guest (Windows Vista) does not have a network connection. Looking at various online documentation and a machine that does work, I guessed that I

Hi, I followed this guide<http://wiki.kartbuilding.net/index.php/Xen_Networking#Routed_Networking_with_NAT_2>, and started my xend service with nat-network support: (network-script network-nat) (vif-script vif-nat) Then I started my domU with the following vif configure: vif = [''ip=10.0.0.1'' ] my domU is a win7 system, and I configured the network as: ip:

Do not set ''bridge'' parameter - let vif-bridge script to do autodetection. Actually ''network-bridge'' never creates xenbr0 interface by default, so defaulting bridge to xenbr0 is senseless.

Hi everyone, I just got a brand new server by Hetzner.de. The thing is, when you have additional IP, to use routed mode (precisely a subnet of IP, story of exposed MAC in their data center etc.) Bridged mode is NOT possible for getting connectivity in VM''s. Traditionally, I''m more confident with "standard" Xen setup, so it''s easy to switch from bridged to

Package: xen-utils-3.0 Version: 3.0.2+hg9656-1 Severity: normal My setup is a basic one. No changes to the /etc/xen/* files. Network in a domU works perfectly fine. But, after shutdowning a domU, I can see the following lines in /var/log/debug: May 6 10:31:45 vaio logger: /etc/xen/scripts/vif-bridge: offline XENBUS_PATH=backend/vif/18/0 May 6 10:31:46 vaio logger: /etc/xen/scripts/vif-bridge:

I have a Xen DomU configuration that was made in the days before libvirt and virt-install. In this configuration I have: vif = [ ''mac=00:16:3e:05:06:01, bridge=xenbr0'', ''mac=00:16:3e:05:06:0a, bridge=xenbr1'' ] and then in xend-config.sxp I define (network-script my-network-bridge) where my-network-bridge is in the scripts directory and looks like this:

I have the following networking setup: - eth0 and eth1 corresponding to the physical ports on the host NIC - bond0 which enslaves eth0 + eth1 - br0 which attaches bond0 - xenbr0 - xenbr5 all of which are internal only networks (10.0.0.0; 10.1.1.0; etc) Br0 is used both for the host to access the outside world as well as DomUs acting as gateway machines for each xenbr network. For example the

Based on Waldi''s RFC at http://lists.xen.org/archives/html/xen-devel/2012-09/msg00943.html To use it set vif.default.script="vif-openvswitch" in /etc/xen/xl.conf or use script=vif-openvswitch in the vif configuration. Appears to do the right thing for PV and HVM guests (including tap devices) and with stubdomains. In order to support VLAN tagging and trunking the
