 Posted: Tue Jan 29, 2013 7:34 am Post subject: kernel config for bridged adapter of virtualbox |
 |
|
In order to use bridged adapter of virtualbox 4.2.6 , how to config kernel ?
I upload my kernel config.
Now I can not use bridged adapter function of virtualbox.
I think the matter is about kernel config.

Thanks

i didn't to read thru your whole kernel-config but you need at least CONFIG_BRIDGE and CONFIG_TUN.
also i think it's necessary to install net-misc/bridge-utils.
GOOD LUCK!

I could be wrong, but IIRC there is no special config necessary for bridging - everything should be handled by vbox-net (or so) module.
The config itself is handled by the virtualbox gui - just change the network adapter settings.

Some wiki says we do not need CONFIG_BRIDGE and CONFIG_TUN for vbox>=2.1.
My now version is 4.2.6.
I also try enable CONFIG_BRIDGE and CONFIG_TUN and install bridge-utils . But I still can not use bridged adapter .
In ubuntu12.04, I can use bridged adapter in network config .
I think if there are other kernel settings I ignore .
But I see the official manual , with no finding about other kernel config.
Thanks

The problem is that Virtualbox has a hard-coded path to /sbin/ifconfig but that program is no longer available there. As a workaround, you could symlink /bin/ifconfig back to /sbin/ifconfig. Alternately, file a bug and request that it be fixed properly. Please note that placing a symlink is only a workaround, not a real fix to the problem, and you should only do that if you will remember to remove the symlink when the problem is fixed.
If you do not understand how to do the workaround or if you have any doubts, please just file a bug and be patient.  It is considered poor practice to manually modify things in /sbin, which is why I label this as a workaround and not a fix. |

I run sudo ln -s /bin/ifconfig /sbin/ifconfig , but the problem still exists.
Do I need CONFIG_BRIDGE and CONFIG_TUN and bridge-utils ?
Thanks

I do not have those. Are you sure that the vboxdrv, vboxnetadp, and vboxnetflt modules are loaded? |

As far as I know, CONFIG_BRIDGE isn't needed, although I have it enabled in my kernel
CONFIG_TUN definitely isn't needed, and nor are bridge-utils.

So strange.
I also cancel CONFIG_BRIDGE and CONFIG_TUN support, and do not install bridge-utils.
Why bridged adapter can not work in my machine ?
Thanks

Hi,
for bridgeing a tun/tap interface you need a tap interface. For creating a tapinterface, you need the following package installed:
| Code: | * sys-apps/usermode-utilities
Available versions: *20070815-r3 {{fuse}}
Homepage: http://user-mode-linux.sourceforge.net/
Description: Tools for use with Usermode Linux virtual machines |
this will install the tunctl command. For the bridge you need the following package
| Code: | * net-misc/bridge-utils
Available versions: *1.2 ~1.4 ~1.5
Homepage: http://bridge.sourceforge.net/
Description: Tools for configuring the Linux kernel 802.1d Ethernet Bridge |
both together will help you create a working bridge with a tun/tap interface. If you need further help for creating a bridge in /etc/conf.d/net, just ask.
greets, bb

I also try what you said . But the problem still exists.
Now I have tried all method above(including ln -s /bin/ifconfig /sbin/ifconfig) , the problem still exists.
Thanks

Can you post the output of "ls -la /dev/net/*" I think you dont have the correct permission set for the tun/tap devices. Also which user do you use for trying to access the "bridge".
greets, bb

Be aware that you don't need TUN/TAP for VirtualBox. I'm not sure that you even
need the kernel CONFIG_BRIDGE, and you certainly don't need bridge-utils,
although you used to a few years ago. VirtualBox does it all itself, these days.
Emerge virtualbox[ and virtualbox modules and add:
| Code: |
# VirtualBox 4.1.22 modules.
modules="vboxdrv vboxnetadp vboxnetflt vboxpci"
|
to /etc/conf.d/modules and you should be good to go.
Will
(You will need to re-emerge virtualbox-modules if you rebuild the kernel.) |

| Code: | $ ls -la /dev/net/*
crw-rw-rw- 1 root root 10, 200 Feb 2 2013 /dev/net/tun |
I use a ordinary user to run vbox.
If I cancel CONFIG_TUN in kernel config, I find no /dev/net/tun.
Thanks

As you can see, you dont have permissions to access the tun device. thats why you need the usermode-utilities. This provides the tunctl tool for changeing permissions while creating the necessary devices. Check this wiki entry for the netconfig:
http://en.gentoo-wiki.com/wiki/KVM#Preparations
There you will find a bridge config with the correct settings for creating you tap devices although its for KVM instead of vbox.
greets bb

Today I update my kernel to gentoo-sources 3.7.10 .
Now every time I run xp guest in vbox, it says : finding an ethernet controller .
I open network connection in xp guest , there is nothing .
Because I can not connect internet in xp guest , so I can not install the ethernet controller driver .
What is the matter ?
Thanks

I also try use kernel config of ubuntu12.04, that makes bridged adapter network config in vbox work.
But I do not how to find that critical item in kernel config.
