[gentoo-user] VirtualBox bridge mode eth0

[gentoo-user] VirtualBox bridge mode eth0

[Joseph]

I've activated Network adapter in VirtualBox (running Windows XP) but I it is not working. 
It works only in NAT mode not in Bridge mode.
The worst part is when I enable bridge mode on second adapter the keyboard lock up, so I need to reboot the box :-/

I've copied the VM into my other box and VirtualBox Network part is working in both Bridge and NAT mode.
So I can not seem to understand why it is working on one box but not the other.

Does it have something to do with Promiscuous Mode?

I'm running VirtualBox Binary in bridge mode (host Gentoo, guest XP). I'm
not sure, but did you configure bridge support in your Linux kernel ?

Promiscuous Mode is needed for bridging to work.  This is why NAT mode 
is preferable, btw, unless you have a good reason to use bridging.

Good suggestion, I just need to find it.
Which option is it?

How to check if network card is set/support "promiscuose" mode?
I know to set it is:
ifconfig eth0 promisc

I need to mount some directory via samba to backup some windows files and in NAT mode was not able to mount the Windows XP directory, it bridge mode 
samba has no problem mounting windows directory.

Probally you are using virtualbox greater than 2.1. Just do this :

Networking --->
    Networking Options --->
    <*> 802.1d Ethernet Bridging

and loaded this three modules. I believe the second one is mandatory to
bridge.
vboxnetadp
vboxnetflt
vboxdrv

I don't think I need this option:
<*> 802.1d Ethernet Bridging
as according to gentoo wiki: 
...Note: The following steps are not necessary for setting up Host Interface on VirtualBox >= 2.1. "

I'm using VirtualBox-bin 3.1.6
and on my two other systems AMD quad core and Intel Quad-core Bridge networking works OK without: <*> 802.1d Ethernet Bridging

No, it is defiantly not the option, when I compile it in VirtualBox will not start and it freezes my box, mouse is not even responding.

grep -i config_bridge .config

CONFIG_BRIDGE refers to iptable (netfilter) I think; beside on my other two boxes CONFIG_BRIDGE is not set and bridge in VirtualBox is working OK.
The only box that VM bridge network is not working is Intel ATOM 330 with with RTL8168c/8111c network card.
It seems to me this card support Promiscuous Mode
http://developer.novell.com/yes/70604.htm
I hope the one in the kernel does.

If you run ifconfig eth0 it should show you in the details of the interface if 
it is running in promiscuous mode.
