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
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

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
