No peth interface for xenbr4 and xenbr5
Hello all,
I have a Xen server with 6 network interfaces, I want a bridge on
all of them.
I use a personal network script like this :
#!/bin/bash
dir=$(dirname "$0")
"$dir/network-bridge" "$@" vifnum=0 netdev=eth0 bridge=xenbr0
"$dir/network-bridge" "$@" vifnum=1 netdev=eth1 bridge=xenbr1
"$dir/network-bridge" "$@"

Number of xenbr''s limited to four on openSuSE 10.2 ?
Hi Group
...
havin'' read whatever I could "google" on this
topic, I didn`t find any
solution:
openSuSE 10.2 (out
of the box), xenkernel, running on HP Proliant DL360G5
(dual
internal networking, plus additional 4-port adapter) gives me eth0 -
eth5, but only peth0 - peth3 (as well as vif0 - vif3 and consequentely
xenbr0 - xenbr3).
I increased the number of

[PATCH linux-2.6.18-xen] make netloop permanent
Hi,
with reference to RH BZ#567540 [0], this patch makes the netloop module permanent (like netback is currently). It reverts parts of xen-unstable c/s 9019:271cb04a4f2b [1] [2] (though that has a typo: "__init clean_loopback", so it was probably changed later too).
The patch fixes the problem of "rmmod netloop" hanging, resulting in blocked tasks and inability to shut down

Bug#396477: network-bridge script exits prematurely
Package: xen-utils-common
Version: 3.0+hg11624-2
Severity: normal
I'm running etch with xen 3.0.3 with a hand-compiled 2.6.18.1
kernel. The /etc/xen/scripts/network-bridge fails to run,
because it (effectively) does this:
set -e
modprobe netloop > /dev/null 2>&1
As I do not have a netloop module (where is it supposed to come
from ? The 2.6.18.1 xen-patched kernel doesn't

xen 3.2 network problems
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

options netloop nloopbacks=<n> ignored
Hi list,
since release 5.3 all kernels ignore
options netloop nloopbacks=<n>
within /etc/modprobe.conf
If <n> is smaller than four there are always four
vifs created.
If <n> is bigger than four the appropriate number
of vifs are created.
Is this expected/new/feature/bug?

Centos and xen network bridge issue
Hi All,
We have a single Centos 5.11 server running a xen hypervisor that went
down hard after an extended power outage this weekend. I'm mostly
familiar for KVM as that is the majority of what our guests run under
and have tried getting up to speed on xen bridging to no avail.
The problem is that after the xen server spun back up, the previously
defined xen bridges were lost. I've

Problem with network-bridge script and veth0
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

where eth0.302 is an interface associated with my vlan 302 (it tags
with this vlan identifier).

VLANs with Xen - work with 1 Gbit, doesn''t with 100 Mbit cards?
I have a strange problem with VLANs with Xen 3.0.4. I signalled it on
Xen-users list, but found no definitive solution to it.
I configure VLANs so that they are available in dom0; domUs don''t know
that they use VLANs.
I use a stock "network-bridge" comming from Xen for setting up networking:

VLAN configuration
Hi to the ML.
I''m new to VLAN configuration, and combining it to XEN is a bit difficult.
I want to use VLAN because it''s possible to "arping" from a domU to an
other, and VLAN looks like; the only solution to prevent that.
May be I''m wrong if someone got a solution, I may be interrested. I''ve
also tryed ebtables, but nothing to prevent arp

loopback.nloopbacks
The FAQ says to use loopback.nloopbacks to limit the number of vif''s and veth''s that show up in dom0. This no longer appears to work. Has this been remove
with no replacement or has this just changed and the FAQ hasn''t kept up?

bonding + VLANs -> Oops/panic, no VLAN on 100 Mbit cards [SOLVED]
As the issue concerns both the -user (configuration) and -devel (OOPS),
I''m sending this message to both lists.
Some time ago I complained about two problems:
- VLANs are not working on machines with 100 Mbit cards
- I get a kernel Oops (sometimes panic) when I try to use bonding and
VLANs with Xen
The root of the issue is the same in both cases: VLAN interfaces must
