vboxnetflt-module on Ubuntu 9.10 doesn't load with modprobe

[Joris Grouwels]

Hi,

I'm running VirtualBox on a Ubuntu 9.10-host with dkms and with a WinXP-guest. When I start the VM with NAT, there is no problem. But when I want to use bridged networking, it appears the vboxnetflt-module isn't loaded. Trying to load it manually gives: $sudo modprobe vboxnetflt FATAL: Error inserting vboxnetflt (/lib/modules/2.6.31-19-386/updates/dkms/vboxnetflt.ko): Invalid module format

I've discovered a thread in this forum ​http://bbs.archlinux.org/viewtopic.php?pid=702814 with exactly the same problem and a workaround with insmod. It is however rather annoying to have to load the module manually using insmod every time.

Regards,

Joris Grouwels

I forgot to mention that I am using Virtualbox 3.1.4 installed using the ubuntu repository. (recently upgraded from 3.1.2)

Why did you install the VBox guest additions at the host? De-install the guest additions from the host and re-setup the host kernel modules with /etc/init.d/vboxdrv setup. If this still does not work, do depmod -a.

Hi Frank,

Thanks for your reply. I installed the guest-additions on the host because I have a dual boot system and sometimes I boot my Linux-partitions from WinXP using VirtualBox. But as I am not doing this very often, I'll try to do what you say and I'll keep you posted. Is there a way to have the guest-additions installed without interference?

regards,

Joris

Dear Frank,

Do you know if there is an easy and clean way to uninstall the guest-additions on Ubuntu? (I installed them with the utility on the guest-additions iso-image, so not through apt-get)

Thanks,

Joris

To uninstall the guest additions you need to execute sh /opt/VBoxGuestAdditions-*/uninstall.sh

Hi Frank,

Thanks, it compiled fine now. I can't restart right now to see if the modules get loaded, but it'll probably be all right. Thanks for your help!

it's the same here with freshly installed opensuse 11.2 64bit and virtualbox 3.1.4

the insmod-workaround works just fine, but is a bit annoying...

and i don't have the guest additions installed on the host, and i never had!

[hemathor]

found another workaround:

since there is a dependency from vboxguest, just remove the vboxguest module and run depmod.

should work until the next update of virtualbox...

[Frank Mehnert]

If there is a vboxguest module on your host, then where does it come from if, like you said, you never installed the guest additions on your host?

[hemathor]

the following kernel modules are installed by the opensuse virtualbox-ose package (from the official opensuse virtualbox repository):

/lib/modules/2.6.31.12-0.1-desktop/updates/vboxdrv.ko /lib/modules/2.6.31.12-0.1-desktop/updates/vboxguest.ko /lib/modules/2.6.31.12-0.1-desktop/updates/vboxnetadp.ko /lib/modules/2.6.31.12-0.1-desktop/updates/vboxnetflt.ko /lib/modules/2.6.31.12-0.1-desktop/updates/vboxvfs.ko /lib/modules/2.6.31.12-0.1-desktop/updates/vboxvideo.ko

so, there is the vboxguest module...

Never mix VirtualBox/PUEL (the version from our public website) with VirtualBox/OSE!
