#4528 Multiple nic use the same bridge

[Valerio Pachera]

I have a guest with 6 interfaces.
Each interface has to bind to a different bridge (br6, br4, br0, br10, br50, br51).
When I created the interfaces, I selected the corresponding bridge.
Cloudmin created the files

-rwxr-xr-x 1 root root 244 dic 22 11:09 /kvm/pfsenseb.cloudmin.extensys.lan-eth0.sh
-rwxr-xr-x 1 root root 244 dic 22 11:09 /kvm/pfsenseb.cloudmin.extensys.lan-eth1.sh
-rwxr-xr-x 1 root root 244 dic 22 11:09 /kvm/pfsenseb.cloudmin.extensys.lan-eth2.sh
-rwxr-xr-x 1 root root 244 dic 22 11:09 /kvm/pfsenseb.cloudmin.extensys.lan-eth3.sh
-rwxr-xr-x 1 root root 244 dic 22 11:09 /kvm/pfsenseb.cloudmin.extensys.lan-eth4.sh
-rwxr-xr-x 1 root root 244 dic 22 11:09 /kvm/pfsenseb.cloudmin.extensys.lan-eth5.sh

All of them are bridging the tap on br6

grep '/sbin/brctl addif'  /kvm/pfsenseb*eth?.sh
/kvm/pfsenseb.cloudmin.extensys.lan-eth0.sh:/sbin/brctl addif br6 $1
/kvm/pfsenseb.cloudmin.extensys.lan-eth1.sh:/sbin/brctl addif br6 $1
/kvm/pfsenseb.cloudmin.extensys.lan-eth2.sh:/sbin/brctl addif br6 $1
/kvm/pfsenseb.cloudmin.extensys.lan-eth3.sh:/sbin/brctl addif br6 $1
/kvm/pfsenseb.cloudmin.extensys.lan-eth4.sh:/sbin/brctl addif br6 $1
/kvm/pfsenseb.cloudmin.extensys.lan-eth5.sh:/sbin/brctl addif br6 $1

E.g.: this interface should bind to br10

cat /kvm/pfsenseb.cloudmin.extensys.lan-eth3.sh

1 2 3 4 5 6 7 8

#!/bin/sh echo $1 >/kvm/pfsenseb.cloudmin.extensys.lan-eth3.tap /sbin/brctl addif br6 $1 /bin/ip link set dev $1 up mtu=`/bin/ip link | grep br6: | sed -e 's/.*mtu //; s/ .*//'` if [ "$mtu" != "" ]; then /bin/ip link set dev $1 mtu $mtu fi

Cloudmin 1.720 on debian wheezy.

Note: br6 is the bridge assinged at first interface.

Can you post the output from the following command, run as root via SSH on your Cloudmin master system :

cloudmin list-interfaces --host pfsenseb.cloudmin.extensys.lan --multiline

[Valerio Pachera]

I created a test guest for this purpose.
The first interface (eth0) uses br6.
The second interface (eth1) uses br4.

This is the requested output:

cloudmin list-interfaces --host test.cloudmin.extensys.lan --multiline
eth0
    Physical interface: eth0
    Address method: Set by VM
    Ethernet address: 02:54:00:B9:81:9A
    Nameserver error: No Linux partitions found in disk image /dev/ssd00/test_cloudmin_extensys_lan_img
    Bridge: br6
    Device model: rtl8139
    Active: No
eth1
    Physical interface: eth1
    Address method: Set by VM
    Ethernet address: 02:54:00:B9:81:BE
    Bridge: br4
    Device model: rtl8139
    Active: No

And this is what i see

grep br /kvm/test.cloudmin.extensys.lan-eth?.sh 
/kvm/test.cloudmin.extensys.lan-eth0.sh:/sbin/brctl addif br6 $1
/kvm/test.cloudmin.extensys.lan-eth0.sh:mtu=`/bin/ip link | grep br6: | sed -e 's/.*mtu //; s/ .*//'`
/kvm/test.cloudmin.extensys.lan-eth1.sh:/sbin/brctl addif br6 $1
/kvm/test.cloudmin.extensys.lan-eth1.sh:mtu=`/bin/ip link | grep br6: | sed -e 's/.*mtu //; s/ .*//'`

Ok, that's clearly broken - the bridges shown by list-interfaces should match those in the .sh files.

Can you also post the output from "brctl show" on your system?
