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.

any comments? if nothing else, is there any way to atomically setup bridge? not on list, please cc. ---------- Forwarded message ---------- Date: Wed, 12 Jan 2005 21:08:15 -0000 From: Ian Pratt <m+Ian.Pratt@cl.cam.ac.uk> To: Adam Sulmicki <adam@cfar.umd.edu>, xen-devel@lists.sourceforge.net Subject: RE: [Xen-devel] nfsroot and brige > hello, > it seems like a catch-22 to

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

Hi, I''ve set up identical (what I think) machines using SLES 10 x86_64, but a new one of those is saying frequently in /var/log/messages: kernel: bond0: received packet with own address as source address A short summary of ifconfig looks like this: bond0 Link encap:Ethernet HWaddr 00:14:4F:2A:12:9C inet addr:132.199.176.78 Bcast:132.199.255.255 Mask:255.255.0.0 eth0

hi fellow XEN-users: I have been trying hard to get this problem fixed, hope I can get some help here. Thanks in advance for your time. I have a typical dom0 + domU XEN setup. after I start xend and network-bridge, I get the default network setup, , peth0 -------- bridge ------------------------------------------------------- |

I''ve just installed Xen on a new CentOS 5.1 system, and I can''t seem to make xenbr0 connect to the network. This system has a single physical network card. Apart from creating a few DomU guests, I have not changed any of the configuration. After running network-bridge, xenbr0 and friends are created, but the address and routing info is not moved. James # ip addr

Hello, I''m observing a weird bug with ip_nat_ftp in a somewhat more complicated constellation. It''s possible that XEN is also involved in this, but I''m not sure. What I''m trying to do is have XEN guest domains on a host, connected via a bridge into a private network. The the privileged domain attaches to this private network and acts as a NAT router to connect

Hi, If one sets xend to use network-bridge and there are no bridges already present then it seems that xend will clone eth0 to peth0, create xenbr0 and add peth0 and vif0.0 as ports on that bridge. If on the other hand xenbr0 is created in /etc/network/interfaces then xend will not do any of that peth0 stuff, nor will it add vif0.0 to xenbr0, yet (barring some changes in iptables rules) things

Hi all, my dom0 is centos5.2 and domU paravirtualized is centos5.1 I can play sound on dom0 but not in domU (name: gasphar), moreover I use wifi as my inet connection and on installing domU cento5.1, I used virt-manager. I know that libvirtd made virbr0 and when changing to xenbr0, I cannot connect to internet but ssh to dom0 is fine! so how do I enable sound device on domU and changing to

I expect that in most routed configurations people use their own network script rather than using the

My very first xen DomU can not ping anything on my network. Well that is not entirely true, it can ping itself. I did not touch any of the scripts in /etc/xen so xen should be using bridging. My pc is running xen-unstable and uses a 3Com PCI 3c905B Just after the ''xen start'' on Dom0 brctl shows: bash-3.00# brctl show xenbr0 bridge name bridge id STP

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

Objet : Xend start and after lose network Hi everybody : My configuration : Dapper 6.06 LTS with all updates Xen 3.0.2.2 My problem : After making ''xend start'', I lose network connections between my server and local network or internet.
