GNU Linux Debian 10 - unable to modprobe vboxsf

Post by canoodler »

Host is Debian 10, Guest is Debian 10 and vboxsf used to work.
since

VirtualBox Version 6.1.2 r135662 (Qt5.11.3)

Code: Select all


hostnamectl; # guest
   Static hostname: debian10template
         Icon name: computer-vm
           Chassis: vm
    Virtualization: oracle
  Operating System: Debian GNU/Linux 10 (buster)
            Kernel: Linux 4.19.0-11-amd64
      Architecture: x86-64

# there is no qemu kvm installed on host
dpkg -l|grep qemu-kvm

apt update;
apt upgrade;
apt install build-essential module-assistant linux-headers-$(uname -r) vim

# recompile guest additions works
/virtualbox/VBoxLinuxAdditions.run

# loading the module ain't workin (never change a running system ay?)
modprobe vboxsf
modprobe: ERROR: could not insert 'vboxsf': Unknown symbol in module, or unknown parameter (see dmesg
no vboxsf no more (can not mount host shared folder)

something is seriously wrong with VBoxGuestAdditions.iso under Debian 10

If it helps anyone here, I have observed the same errors when vboxsf is modprobed on a Gentoo Linux guest.

Start the guest from full normal shutdown, not save-state. Run until you see the problem happen, then shut down the guest from within the guest OS if possible. If not possible, close the Virtualbox window for the guest with the Power Off option set.

Right-click the guest in the main Virtualbox window's guest list, choose Show Log. Save the far left tab's log, zip it, and post the zip file, using the forum's Upload Attachment tab.

Also, right-click the guest in the main Virtualbox window's guest list, choose Show in File Manager. Zip the guest's .vbox file, and post the zip file, using the forum's Upload Attachment tab.

Sorry for the long time responding. This issue in my Gentoo guest still persists. Attached is my log file per the request above.

On the host, you're running the VirtualBox version 6.1.16 from Oracle, so far, so good. In the guest, you're running the VirtualBox Guest Additions (GA) 6.1.16 from Gentoo (not from Oracle), and the vboxguest.ko kernel module is version 6.0.0. I'd suggest to uninstall the GA, and install the official GA from Oracle.

Thanks, I switched to the Oracle GA and the errors are gone. Now to learn about shared folders! :D
