Re: [opensuse] VirtualBox bridged connection in OpenSuse 10.3

Hi,

I have VirtualBox 1.6 ose, OpenSuse 10.3.
There are 2 physical network cards - eth0 and eth1.

eth0 is connected with a wire to ADSL-modem, gets its address dhcp -
192.168.1.2

eth1 is not connected to anywhere. I want configure a bridge on it for
VirtualBox, so guest OS (ALT Linux Server) would become part of local
network (so I could ping it from my host suse, and my host could be
pinged from guest os) and also they all should have inet, connected
though eth0

I was following different instructions -
http://en.opensuse.org/Virtualbox_Network_Bridging ,
http://dotlinux.blogspot.com/2007/12/virtualbox.html , and also some
other - all without success. I someone has the same configuration,
which >really< works - please post it here.

Here are my steps:

#######1. Created file /etc/sysconfig/network/ifcfg-br0:

BRIDGE_MAXAGE='20'
BRIDGE_PATHCOSTS='19'

#######2. Changed file /etc/sysconfig/network/ifcfg-eth1:
#ifcfg-eth1
BOOTPROTO=static

#######3. Execute /etc/init.d/network restart

####### 5. Virtual machine is already configured to use host interface
vbox0

Start guest OS (all further commands are made inside it). Startup log
on the "Starting Network" stage has rather long pause, then [Done].
Login with root, ifconfig shows network device eth0 without ip
assigned.
Make ifconfig eth0 192.168.1.102 netmask 255.255.255.0

Nothing pings except itself. On what step did I miss something?





***************
Also, if I make bridge on eth0 instead of eth1 (BRIDGE_PORTS='eth0' ), then

with 'network restart' I have a bit different message:
...
br0
br0 Ports: [eth0]
br0 forwarddelay (see man ifcfg-bridge) .... ready
br0 IP address: 192.168.1.101/24
...

Then I all the same. ifconfig looks the same, but the host stops
pinging modem 192.168.1.1) and so there is no inet on the host suse.

But the guest OS has 192.168.1.3 assigned to eth0 just after loading,
pings model and has inet. Ping does go to host 192.168.1.2 (but in
this case as I understand it should not as eth0 is taken by bridge)


Thank's
Anton

Virtualbox 1.6 host networking doesn't work correctly
(http://www.virtualbox.org/ticket/1471). I have used version 1.5.2 without
problems, just add both eth0 and eth1 to the bridge and check whether vbox0
state in "brctl showstp br0" is "forwarding".
