[Xen-users] network-bridge with vlan and problems ...

hi!

i try to set up my xen enviroment to a vlan bridge ...

/etc/xen/scripts/network-bridge start netdev=eth4.850 bridge=xen-br850 
antispoof=no

Link veth4.850 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
driver is compiled statically into the kernel, then you may set the parameter
using netloop.nloopbacks=<N> on the domain 0 kernel command line.

ip link show | grep veth
3: veth0: <BROADCAST,MULTICAST> mtu 1500 qdisc noop
5: veth1: <BROADCAST,MULTICAST> mtu 1500 qdisc noop
7: veth2: <BROADCAST,MULTICAST> mtu 1500 qdisc noop
9: veth3: <BROADCAST,MULTICAST> mtu 1500 qdisc noop
11: veth4: <BROADCAST,MULTICAST> mtu 1500 qdisc noop
13: veth5: <BROADCAST,MULTICAST> mtu 1500 qdisc noop
15: veth6: <BROADCAST,MULTICAST> mtu 1500 qdisc noop
17: veth7: <BROADCAST,MULTICAST> mtu 1500 qdisc noop
19: veth8: <BROADCAST,MULTICAST> mtu 1500 qdisc noop
21: veth9: <BROADCAST,MULTICAST> mtu 1500 qdisc noop
23: veth10: <BROADCAST,MULTICAST> mtu 1500 qdisc noop
25: veth11: <BROADCAST,MULTICAST> mtu 1500 qdisc noop
27: veth12: <BROADCAST,MULTICAST> mtu 1500 qdisc noop
29: veth13: <BROADCAST,MULTICAST> mtu 1500 qdisc noop
31: veth14: <BROADCAST,MULTICAST> mtu 1500 qdisc noop
33: veth15: <BROADCAST,MULTICAST> mtu 1500 qdisc noop

my debian networking config:

iface xen-br850 inet manual
        up ifconfig eth4 up
        up vconfig add eth4 850
        up /sbin/ifconfig eth4.850 up
        up ifconfig eth4.850 192.168.1.15 netmask 255.255.255.192
        up route add default gw 192.168.1.1
        up /etc/xen/scripts/network-bridge start netdev=eth4.850 
bridge=xen-br850 antispoof=no
        down /etc/xen/scripts/network-bridge stop netdev=eth4.850 
bridge=xen-br850 antispoof=no
        down vconfig rem eth4.850

how can i create veth4.850???

eth4.850 (the vlan interface) is up and runs.

thanks for any hint!

with friendly greetings,

christian

Re: [Xen-users] network-bridge with vlan and problems ...

Hi,

I don't know if this is the right way, but I've created my own script to
create bridges. I leave /etc/xen/script/network-bridge to create default
bridge and use skript create_bridge to create bridge for each vlan

#!/bin/sh
# usage: ./create_bridge vlan_number

bridge=$1
bridge="xenbr${bridge}"
vlan=$1
vlan="vlan${vlan}"
echo createing ${bridge}
brctl addbr ${bridge}
brctl stp ${bridge} off
brctl setfd ${bridge} 0
brctl addif ${bridge} ${vlan}
ip link set ${bridge} up

Script is for suse. I guess you must change line vlan=... to
vlan=eth0.${vlan} for Debian? Like I sad, I don't know if this is the right
way...

bye

Re: [Xen-users] network-bridge with vlan and problems ...

Hi!

You can try it in this way and I think it´s the most choosen way:

Create a file e.g. named network-bridge-costum with the following cxontent:

vconfig set_name_type DEV_PLUS_VID_NO_PAD
vconfig add ethX VLANID1
vconfig add ethX VLANID2
dir=$(dirname "$0")
"$dir/network-bridge" "$@" netdev=ethX.VLANID1 vifnum=0
bridge=xenbrXX
"$dir/network-bridge" "$@" netdev=ethX.VLANID2 vifnum=1
bridge=xenbrXX

and edit the networkconfiguration in xend-config.sxp:

(network-script network-bridge-costum)


And now everything should work fine.

Bye

Stefan
