Do bridges or vif defragment IP-packets?
We have a SLES11 system with XEN 3.3 and configured an internal bridge "intbr1" with interfaces "vif2.1" and "vif9.1" to two Linux-guests:

XEN multiple bridge problem - VM won' start!
Hi,
I've been using CentOS & Xen on a server that has 2 VM's configured. The
default configuration includes one physical iface that is propagated (by a
default bridge) to the VM's.
Since I wanted to configure additional physical iface, define a new bridge
and propagate it to the viface-s of the VM's, i configured the bridge/phys.
iface and brought it up (here are

help--dom0 network goes unpingable when xend starts
I installed 64-bit xen 3.1.0 (from xensource.com tarballs) on
three new machines today, using a configuration setup that I''ve
used successfully many times before. However, I encountered a
new problem.
These are Dell Poweredge 1950 servers, by the way.

Xen 4.1.0, multiple network interfaces, network-bridge failing to create multiple bridges
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:

adding static route via network setup fails
I want to add the following route command
route add -net 192.168.2.0/27 gw 192.168.2.3
via the normal network setup.
The result should be the following routing table (the first line):
192.168.2.0/27 via 192.168.2.3 dev xenbr1 scope link
192.168.2.0/27 dev eth2 proto kernel scope link src 192.168.2.4

Infinite loop shutting down xendomains
Pardon me for a long detailed post but this looks pretty serious. The
bottom line is that, when I attempt to shut down or reboot my simple
xen-2.0.7 server running FC3 with two domUs, shutting down xendomains
appears to send python into an infinite loop. This may be due to a
serious misconfiguration on my part but it is certainly a big problem.
If we shutdown the domUs manually first, the

installing DomU with two network bridges via virt-install
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

order of network interfaces in domU messed up?
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.

strange VLAN / domu behavior
Hi there!
I am currently setting up a Xen box on 3 VLans, each VLan interface is in a
bridge and currently, dom0 is reachable from on of these and is performing
great.
My only problem is with domU : it can ping anything but it won''t work for
TCP and UDP protocol UNLESS I do a manual tcpdump on my vlan interface.

Bug#702337: xen-xapi / Open vSwitch not really working
Package: xcp-xapi
Version: 1.3.2-14
Severity: important
I chose the Open vSwitch (ovs) networking mode when I installed XCP
# cat /etc/xcp/network.conf

Whenever I boot a VM, I notice that the vif interface is created (e.g.
vif1.0) on dom0, and the vif is added to the ovs bridge (I can see it in
the output of ovs-vsctl show)
However, there is no connectivity, I can't ping the

Frustrating experience - Xen networking.
Hello,
I am having a frustrating time trying to get bridge networking working.
I''ve gone over the Wiki page on the topic, a few of the howtoforge pages and
everything that I am doing is failing utterly.
What I want to achieve is to have Dom0 be a stub running two DomUs. One
DomU being a router/firewall and the other being the rest of what is on the
current machine.

Hello,
I''m new to Xen (and this mailing-list) and facing some problems with
the network. I''m stuck and don''t know how to continue. And Google
isn''t very helpful either...
My setup:
- Ubuntu 7.10 for dom0 and Debian 4.0 for all domU
- 4 physical NIC (DHCP from my ISP, internal LAN, DMZ & WLAN)
- 1 Dom as firewall/router
- 1 domU with internal services

Trouble creating DomU with 2 NICs
Hey folks,
I created a DomU, installed Linux, and then realized I''d only given it
1 NIC so brought it down to edit the cfg file to give it another NIC.
Originally I just had :

And so I guess the defaults worked for the 1 NIC. So I changed it to :
