similar to: Multiple Bridges and Multiple physical nic''s

Hi *, having built Xen 4.1.0 and running my Dom0 on Slackware 13.1, I''m trying to assign different physical network interfaces to different DomU guests: vif = [ ''bridge=ethX'' ] in the DomU configuration files. My /etc/xen/scripts/network-bridge script, however, doesn''t create more than one bridge: root@cen:~# /etc/xen/scripts/network-bridge start

While I am still in the process of working through this here are the steps I am taking to set up each machine. 1) Since each of my servers have multiple NIC ports I bond them together (see page 34 of the Administrators Guide) first. This is best down from the physical server and not via the remote console. If you do it remotely you will then have to reconfigure the management port before

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

Hi, I have two physical machines connected through a switch in a 192.168.1.* subnet. Dom0''s are assigned static ip addresses 192.168.1.100, 192.168.1.101 respectively. Dom0''s can ping each other. Each physical machine has a domu guest and static address assigned to domu''s are 192.168.1.200, 192.168.1.201 respectively. However domu''s can neither ping each other

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, in the official XenNetworking ( http://wiki.xensource.com/xenwiki/XenNetworking ) i didn''t find reported how the NAT configuration works with xen. Does anybody know how the vifX.Y (10.X.X.128), gateway of any domU ethX (10.X.X.1) talk with the real ethX of the dom0? Thanks Enrico _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com

You are very welcome. One thing that I am working on now involves removing the step toward the beginning: xe pif-reconfigure-ip uuid=<UUID of the bond created above> mode=static gateway=<GATEWAY> IP=<IP ADDRESS> netmask=<NETMASK> DNS=<DNS SERVER ADDRESS> I do not believe that this step is necessary since we will not use the pif directly. We will use

Ran into a strange issue with XEN on CentOS that I think is specific to CentOS, which is why I'm starting by posting to this list first, I'll post on the XEN list depending on responses. My sense is this issue has something to do with how CentOS handles network setup on first boot of the XEN kernel. - Installed a brand new CentOS 5.3 server with minimal packages. - Installed XEN,

Recently I installed Xen on my computer.But there are some problems during the starting time. The /var/log/xen/xend.log is follows: [2011-06-10 14:24:36 1395] DEBUG (XendDomainInfo:1794) Storing domain details: {''cpu/3/availability'': ''online'', ''description'': '''', ''console/limit'': ''1048576'',

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

I observed a strange networking behaviour of my Debian virtual host in function of the MAC address I use. It seems that when I use an existing constructor code, networking works without any problem, but is impossible in the other case... Ex. : - vif = [ ''mac=aa:00:00:00:00:55, bridge=xen-br0'' ] -> no problem - vif = [ ''mac=df:00:00:00:00:55,

Have 4 xen servers with windows domains. 2 work OK and 2 have xp domains with slow network performance. Doing most of the testing on a xen system that currently is not in production. Running xen 4.0 with 2.6.32 kernel from lenny backports. Have xp service pack3 freshly installed with no updates. Installed gplpv gplpv_XP_0.11.0.213.msi hdtack gives 60mb/sec which is good iperf gives ~15Mbits/sec

Hello, i''ve an HP proliant dl385g2 server with AMD64 Opteron processor. i''ve rightly installed Debian Ecth and configured as Dom0. I''ve installed the package via apt. well i would install 7 virtual server... one as mail server, one as db mysql server, 5 as web server. i''m installed my first DomU. i''ve created a LVM with my first DomU, is a Debian Ecth

Hi, I have a box with XEN enabled. Specs : Gentoo 10.0 AMD64 XEN 4.0.0 The server is connected on our network through two physicals NIC. Actually, I''m using a VLAN on each NIC and bridge the domU in it. But now I must create an additional domU which should be in an different VLAN. The best solution is to set a trunk on the switch and use 802.1q directly on the dom0. I found this site

Hi, is there any possibility to get a XEN DomO and DomU running with bridget and routed mode together. The reason behind this is, to get the requests via the official IPs to the DomU''s (routed-mode) and the interworking between the DomU''s with connected with help of the (bridged-mode). I got it work, with setting everything up manually. But as I understood the

Hi. I have another question, hopefully easier than my last: Do all physical interfaces in dom0 need to have an IP addresse in order to be used as a bridge by guest domains? I thought that the interface would have to merely be "up" but not necessarily have an IP address configured since bridging is done at layer 2. But alas, if I don''t configure an IP address on dom0 the bridge

Hi, Has anyone tried upgrading xen domu's from 5.2 to 5.3? I just did a yum upgrade glibc & yum upgrade yum. All appeared to go well but when I rebooted and tried to connect to the network, I could not. Looking at /etc/sysconfig/network-scripts I see that the that there is now an ifcfg-eth0 and an ifcfg-eth0.bak. ifcfg-eth0 now contains configuration for a dynamically configured

Hello, I am experimenting with Snort and other IDS and I would like to use Xen for these tests. This would require me to use port mirroring to sent a bunch of packets to a NIC located on my Xen machine. I don''t really know how Xen networking works, but is it possible to give a domU direct access to a NIC ? Or at least give it enough access so that it can see packets that are not for the

Hi Xen-users, I am trying to boot of my fist guest domain. The below attached message was thrown on the screen. I am not quite sure that the below information is sufficient to root cause the issue. Where do i look for additional logs to root cause the issue. Appreciate any info that you think might be useful. Thanks, Karthik xm create -c guest1.conf vmid=2 Using config file
