Issue: Failed to create the host-only network interface

[Borhanx]

Hi All ,

I've big problem with Virtualbox 4.2
I'm using ubuntu 12.10 , 64bit.
and I installed virtualbox 4.2 with this exactly steps:
http://www.n00bsonubuntu.net/content/ho ... ntu-12-10/
(I did this steps extactly)

Then when I opened Virtualbox -> File -> Prefrences > Network > add host-only network (lns)

I got this error message:

Failed to create the host-only network interface
VBoxNetAdctl: Error while adding new interface: failed to open
/dev/vboxnetctl: No such file or directory

( I attached error message picture in the topic)

when i type this command:

Code: Select all

borhan@ubuntu:~$ cd /dev/vboxnetctl/
bash: cd: /dev/vboxnetctl/: No such file or directory

(so the vboxnetctl directory doesn't exsist !)

How can I fix this problem ?

Couple of things that you need to do.

1) add your user name to the vboxusers group.
In a host terminal run this:

• Code: Select all

  sudo usermod -aG vboxusers <your username>

  Replace <your username> with the name you use to log in. Type your user password when prompted.
  Be sure to log off and back in to finalize the change in permissions

2) instead of logging off reboot the host and see if you still have this issue.

I did what u said , exactly.
and I made reboot

then I still have the same problem when I trying to create host-only network adapter.

the problem is he can't find the directory !

after ur command line
i did this, is the result normal ?
borhan@ubuntu:~$ id
uid=1000(borhan) gid=1000(borhan) groups=1000(borhan),4(adm),24(cdrom),27(sudo),30(dip),46(plugdev),107(lpadmin),124(sambashare),125(winbindd_priv)

Open a terminal on the host and post the results of the following:

Code: Select all

VBoxManage -v

[Borhanx]

Done.

Code: Select all

root@ubuntu:/dev# VBoxManage -v
WARNING: The vboxdrv kernel module is not loaded. Either there is no module
         available for the current kernel (3.5.0-25-generic) or it failed to

           sudo /etc/init.d/vboxdrv setup

         You will not be able to start VMs until this problem is fixed.

[Perryg]

Why are you in root?
Do this with the normal user that installed VirtualBox and try again.

[Borhanx]

Sorry, i did it now.

Code: Select all

borhan@ubuntu:/dev$ VBoxManage -v
WARNING: The vboxdrv kernel module is not loaded. Either there is no module
         available for the current kernel (3.5.0-25-generic) or it failed to

         You will not be able to start VMs until this problem is fixed.
4.2.6r82870
borhan@ubuntu:/dev$ 

[Perryg]

Well the results are the same and it indicates that VirtualBox is not installed properly.

When installing did you see any errors?

Post the /var/log/vbox-install.log (as an attachment)

[Borhanx]

this is log

Code: Select all

[Perryg]

The log is telling you what your problem is.

You need to install the headers to match you running kernel.
Then run /etc/init.d/vboxdrv setup

[Borhanx]

Finally, i fix the problem by this command
http://askubuntu.com/questions/218320/v ... ox-upgrade

the problem was in kernel headers

and i tried to create host-only network adapter, and it's successful created.


thanks too much dear Perryg .
appreciate your efforts.
