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.

It''s effectively a point to point link, allowing domain 0 to connect on to the bridge in the same manner that other domains do. (before, packets to domain 0 were short-cutted and came off the

Hi, I am using Xen 4.1.1 with Linux 3.0.1 kernel. Previously (Xen 3.4.4 and linux kernel 2.6.18) Xen by default created veth0 <--> vif0.0 pair in dom0. With Xen 4.1.1 these pairs are missing in dom0. Using command ''ip link add type veth'' I can create veth0 and veth1 but vif0.0 is still missing in dom0. (When new domU created I can see vif1.x created) Could you please help

Package: xen-utils-common Version: 3.2.0-2 Hello We used the script "network-bridge" on our Xen servers based on "etch" (xen-utils-common 3.0.3-0-2) to setup bridge configuration. This script created a bridge "xenbr0", renamed "eth0" to "peth0", renamed "veth0" to "eth0" and added "peth0" and "vif0.0" to

When does vif0.0 get created? Is there some shell magic?

Hello, I just setup a Xen server and wanted to use bond0 for my network connection. I ended up downloading and addeding the attatched file and making the following change in /etc/xen/xend-config.sxp. I added this line: (network-script 'network-bond netdev=bond0') Would this line be a good one to add to the commented lines and include the network-bond file in the scripts? Just thought

Hello, I''m still having problems with my ''upgrade'' to the FC4 xen packages. I have a domain with two virtual network interfaces, in two different subnets. For a domain with a single interface, the new networkd setup script works fine, but it does work (for me) with two interfaces. It used to work fine, and I used to set it up with simply by more or less blindly doing

Dear I need create second bridge xenbr1 for separate traffic between my virtual machine , I following this step but show message that Link veth0 is missing, how I can create veth0 ? When I run script for create xenbr1 ./network-bridge netdev=eth1 bridge=xenbr1 start Shwo this message Link veth0 is missing. This may be because you have reached the limit of the number of interfaces that the

This patch adds an ACM hook into the network scripts (/etc/xen/scripts). It adds iptables rules that enforce mandatory access control on network packets exchanged between virtual interfaces. If ACM is active, this patch sets the default FORWARD policy in Dom0 to DROP and adds iptables ACCEPT rules between vifs that belong to domains that are permitted to share (determined by using the

Hello, Since my last update of xen, I am having problems with bridges and xen. When I want to start a bridge on the dom0 (to run a domU in a different vlan than the default) I run /etc/xen/scripts/network-bridge start netdev=eth0.302 bridge=xen-br302 antispoof=no where eth0.302 is an interface associated with my vlan 302 (it tags with this vlan identifier). The problem I have is that it

Hi list. I started with Xen yesterday, but I am facing a bit of a problem. My system had always configure eth0 with 10.0.0.4/8 I am using Xen unstable source (on Debian sid) Now I installed Xen, rebooted the machine, and first the usual network is coming up and then the xend will be started. I''ll end up with this, but I am wondering if this should be the way of things to be

Hi, I try to get networking running with xen 3.2, but it seems I fail miserably. I am on sles10sp1, with xen 3.2.0, and kernel rpm''s installed from SP2. I configured in /etc/sysconfig/network the NETWORK_LIST: NETWORK_LIST="bridge,0,default,00:DE:AD:BE:EF,192.168.8.13/24,dhcp-off" but an ifconfig xenbr0 still shows the mac address of peth0 fe:ff:ff:ff:ff:ff. Initially, I

Hello All, I'm trying to figure out why xen-utils-common 3.2 doesn't suport bridging on multiple interfaces. I've been digging around /etc/xen/scripts/network-bridges. And modified it so that during boot, when executed the script writes into /tmp/netbr file, but I commented out code that actually creates bridges. I discovered that this script is called three times during boot, I

Hi, I''m using RHEL linux 5.1, I can''t add the another NIC to my virtual machine. # /etc/xen/scripts/network-bridge start Link veth0 is missing. This may be because you have reached the limit of the number of interfaces that the loopback driver supports. If the loopback driver is a module, you may raise this limit by passing it as a parameter (nloopbacks=<N>); if the

Hi, I have a strange problem with my networking setup. I read all forums around the world where people had similar problems, but couldn''t find a solution. I have an Attansic L1 gigeth chip on my mainboard. This chip works OK in stock Ubuntu Gutsy (development) 2.6.22-9-generic kernel. When I boot into Xen, and after the bridge is created, the network stops working. Some info: - If I

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 everybody, I have an odd problem with iptables using a Xen bridge setup. I don''t know if it would be better to post to netfilter Mailing-List. But I hope someone here know how to solve it.
