similar to: using both bridged and routed networking

So Working on CEntOS 5 I am trying to sett up Xen with 2 bridges, one that connects dom0 and most of the domU to the physical card and the out to the network. Got that figured out no problem, now i want to have a second bridge that runs a local network for all the doms that doesn''t connect to the network. With code I have found used in multiple places I can easily get 2 bridges, and

Hi guys, i have 4 Xen servers, two with Xen 3.2.1 and the other two with Xen 4. All four servers with 3 network card attached to different networks, 3 of these interfaces are bridges (configured in the ''/etc/network/interfaces'' config file, NOT in xend-config.sxp file) and one is used for the ISCSI service, where the virtual machines are loaded. The problem is,

Hi all, Does anyone know what the correct steps are to add a XEN bridge, let''s say xenbr0 to Debian Squeeze? I have added the following to /etc/network/interfaces # XEN Bridge auto xenbr0 iface xenbr0 inet manual bridge ports eth0 bridge_stp off bridge_fd 0 And then rebooted the server but brctl show still shows eth0 as bridge: newusaxen:~# brctl

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

Hi ! What is the best way to use eth1 of my dom0 in my domU ? i tried that in Dom0 but bridge don''t want comes up : ./xen-network-common.sh "network-bridge net-dev=eth1 bridge=brint virtnum=1" Thanks Michael _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

Hello, I use xen for a few months now and I upgraded to opensuse 10.3 with xen 3.1 (64bit versions) recently. Everything works fine, but there is a problem when I change xend-config.sxp to use my own network script (it''s slightly modified version of network-virtual scripts from http://en.opensuse.org/Xen3_yet_another_Virtual_Network_Concept ) instead of default network-bridge script.

Hi, Question on setting up networking in xen. I want to do the following on my laptop: dom0 is attached to eth0 and ath0. dom1 is going to by my virtual firewall for all my virtual machines. So I assume 3 interfaces, a bridge to eth0, ath0 and a virtual interface? dom2 and so on will route all their traffic through dom1 (through the virtual interface) I''ve read the documentation a

Hello with XEN 3.4.x antispoof=yes works on a bridge setup. I am using this line in xend-config.sxp (network-script ''network-bridge antispoof=yes'') It creates this under IPTABLES FORWARD chain: ACCEPT all -- anywhere anywhere PHYSDEV match --physdev-in peth0 Under XEN 4.0.1 it is not working, it does not create a IPTABLES rule. Customers can

This is all on SuSE enterprise 10 Our server was moved to a new location last night. After powerup there was no sign of networking so our ISP reconfigured the box. Outbound connectivity had previously been through eth1 but is now through eth0 Since restarting Xen I now have no network connectivity through the hosts. I have tried to provide all the relevant details below. If anyone has a moment

hello, I want to configure 2 interface like this eth0 for LAN is 172.16.0.3 eth1 for SAN is 192.168.0.13 I want all VM can access to all network my configuration is : (network-script ''network-bridge netdev=eth0'') to have peth0 and I have a peth0 interface (network-script ''network-bridge netdev=eth1'') to have peth1but I don''t have a peth1 interface

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 am running Xen on Debian wheezy. I switched from routed networking to bridged networking. Now I can''t seem to get eth0 to come up. When the network script tries to bring it up, it gets an error: RTNETLINK answers: File exists Any tips? details below brian root@trout:/etc/xen# egrep -v ''#|^ *$'' xend-config.sxp (network-script network-bridge) (vif-script vif-bridge)

Hi I was experimenting with Xen(-2.0) on NetBSD last summer and I have been trying it on Debian GNU/Linux recently. I was surprised to see that my guest OS had no Internet connectivity. I took the Xen documentation, but did not find any clue: the doc basically tells ``everything should work out of the box''. I spoke about that with a friend who had already used Xen under Debian and he

(If this is a double post, I apologize, my email client crashed when I first sent it) I need some help to configure a secure network on my Xen server. I have been looking online and it seems a I need a routed network. But I am having a terrible time implementing it. My setup: Xen 3.4.2 CentOS 5.5 Dom0 1 NIC (eth0) All guests will be HVM What I want to do is something similar to a firewall

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, 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

I normally use the network-script parameter in the '/etc/xen/xend-config.sxp' configuration file to configure network bridges. However, the latest release of Xen4CentOS (which comes with Xen 4.4.1) has xend disabled by default. Can I continue to use network-script without xend? If not what is the recommended method for automatically configuring network bridges with the latest release of

I saw the pci dev''s config is different from vbd/vnif with following comments: # Parsing the device SXP''s. In most cases, the SXP looks # like this: # # [device, [vif, [mac, xx:xx:xx:xx:xx:xx], [ip 1.3.4.5]]] # # However, for PCI devices it looks like this: # # [device, [pci, [dev, [domain, 0], [bus, 0], [slot, 1]]]] # # It seems the reasoning for this difference is
