Hi,
just the normal way - create an bridge with eth1 as connected interface and use this bridge for VMs/CTs.

Hi,
access have only the CTs/VMs which have an bridged interface in this vlan (mean on this bridge).
You can look with brctl which machines are connected:

brctl show
bridge name     bridge id               STP enabled     interfaces
vmbr0           8000.000f53073c90       no              eth0
vmbr10          8000.000f53073c91       no              eth1.10
                                                        tap203i0
                                                        tap205i2
                                                        tap212i0
                                                        veth232.0
vmbr300         8000.000f53073c91       no              eth1.300
                                                        tap220i1

Hi udo,

thanks for reply.

We have configured a new bridge with

name: vmbr1
autostart: yes
ip: local ip
subnetz: our subnetz
gateway: none

if we restart the network service we get the message:
Ignoring unknown interface eth1=eth1.

But before we have used eth1 normal with internal ip.

Do you have a idea?

regards

solution: we must restart complete server, after this its works. very thanks

Hi,
that's normal.

You can all things doing also on the fly with "brctl" and "ip" and so on, but an reboot is the safe way (and you know, that your changes will work).
