hi

we have a setup with kernel 2.6.14.4, just upgraded, patcht against
vserver 2.0.1. the hosts use bridged network interfaces vor L2
redundancy. also, we are working with VLANs to separate traffic between
hosts and vservers.

when we were installing util-vserver-0.30.209 every time we stopped a
vserver, not only his private interface got down, but the whole bridge
including all other interfaces of all vservers...

after downgrading to util-vserver-0.30.207, everything works fine again.

a sample configuration of a vserver:
$ more 0/*
::::::::::::::
0/dev
::::::::::::::
br0.2
::::::::::::::
0/ip
::::::::::::::
62.12.154.32
::::::::::::::
0/name
::::::::::::::
public
::::::::::::::
0/prefix
::::::::::::::
24

the relevant part output part of ifconfig (on the host):
$ sudo ifconfig

br0.2 Link encap:Ethernet HWaddr 00:11:43:E3:11:39
           inet addr:62.12.154.12 Bcast:62.255.255.255 Mask:255.255.255.0
           UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
           RX packets:2808646 errors:0 dropped:0 overruns:0 frame:0
           TX packets:3383124 errors:0 dropped:0 overruns:0 carrier:0
           collisions:0 txqueuelen:0
           RX bytes:424670986 (404.9 MiB) TX bytes:1168460377 (1.0 GiB)

br0.2:pub Link encap:Ethernet HWaddr 00:11:43:E3:11:39
           inet addr:62.12.154.32 Bcast:62.12.154.255 Mask:255.255.255.0
           UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1

the first is the host bridge br0.2. the second is the aliased interface
of the vserver. both are in VLAN 2.

output of ip addr list:

$ ip addr list
1: lo: <LOOPBACK,UP> mtu 16436 qdisc noqueue
     link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
     inet 127.0.0.1/8 scope host lo
2: eth0: <BROADCAST,MULTICAST,UP> mtu 1500 qdisc pfifo_fast qlen 1000
     link/ether 00:11:43:e3:11:39 brd ff:ff:ff:ff:ff:ff
3: eth1: <BROADCAST,MULTICAST,UP> mtu 1500 qdisc pfifo_fast qlen 1000
     link/ether 00:11:43:e3:11:3a brd ff:ff:ff:ff:ff:ff
4: eth2: <BROADCAST,MULTICAST,UP> mtu 1500 qdisc pfifo_fast qlen 1000
     link/ether 00:12:17:54:de:1e brd ff:ff:ff:ff:ff:ff
5: br0: <BROADCAST,MULTICAST,UP> mtu 1500 qdisc noqueue
     link/ether 00:11:43:e3:11:39 brd ff:ff:ff:ff:ff:ff
6: br0.2: <BROADCAST,MULTICAST,UP> mtu 1500 qdisc noqueue
     link/ether 00:11:43:e3:11:39 brd ff:ff:ff:ff:ff:ff
     inet 62.12.154.12/24 brd 62.255.255.255 scope global br0.2
     inet 62.12.154.102/24 brd 62.12.154.255 scope global secondary br0.2:0
     inet 62.12.154.57/24 brd 62.12.154.255 scope global secondary
br0.2:public
     inet 62.12.154.56/24 brd 62.12.154.255 scope global secondary
br0.2:public
     inet 62.12.154.32/24 brd 62.12.154.255 scope global secondary
br0.2:public

where all br0.2:public are vserver interfaces.

we first where thinking that it could cause problems that all vserver
interface aliases are the same. but because also the host interface
(br0.2) gets down, we aren't convinced of this anymore...

does anyone has a hint about this?

thanks and regards
