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:

####### 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".

Thank's for info. Can you please provide a bit more info on how the host system network should be configured for that?

Try "BOOTPROTO='dhcp'" in ifcfg-br0 and remove the IPADDR line. Then enter "/etc/rc.d/vboxnet start". Make sure that eth0, eth1 and vbox0 are set to IP address 0.0.0.0. You may also need to disable the firewall, it might interfere in some cases.

Thank's for advice, all works right now - with bridge attached to eth0, and eth0 ip set to 0.0.0.0. And even in my VirtualBox, though it has version 1.6.0 My initial error was that I did not want to touch working eth0 and instead wanted to attach bridge to eth1 which is physically connected to nowhere. I was not very confident in this area, but after this task have made a big step forward.

Does your bridge (br0) come up automatically? My bridge also works fine after following the steps in the help file, but NetworkManager seems to ignore the br0 interface, I have to manually ifup it every morning?. (I use wireless at home and wired at work, on laptop; so I like NM automatically connecting to my home wifi)

--

The bridge itself is initialized automatically, but I have to recreate vbox0 Virtual Box interface each time the network is restarted with "/usr/bin/VBoxAddIF vbox0 benderamp br0". I think this line could be put to some kind of network init script, but I did not try to go deeper into this problem. br0 interface is not shown in Yast network configuration module, but I do not care as I do not use NetworkManager - I like KInternet much better and it also does not ignore br0 -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
