Shared Folders don't work with Ubuntu 8.10 as guest

[Poseidon]

Host: Windows XP pro sp2
Guest: Ubuntu 8.10
Installing Guest Additions worked. Mouse Integration worked after putting these lines into xorg.conf

Section "InputDevice"
   Identifier   "Configured Mouse"
   Driver       "vboxmouse"
   Option       "CorePointer"
EndSection

Mounting a shared Folder fails with the following message:

/sbin/mount.vboxsf: mounting failed with the error: No such device

'sudo modprobe vboxvfs' fails with the following message:

FATAL: Error inserting vboxvfs (/lib/modules/2.6.27-7-generic/updates/dkms/vboxvfs.ko): Unknown symbol in module, or unknown parameter (see dmesg)

The same error is also described ​here and ​here.

Since i don't know what of this is of interest, im adding the whole output of dmesg.

Output of dmesg

Try the following:

1) remove xorg.conf altogether on the guest. (Keep a backup of course, just in case...)

2) reinstall the Guest Additions, making sure that you use the Additions from VirtualBox 2.0.6.

[Michael Thayer]

Perhaps better change the order there, and install the new additions before you remove xorg.conf.

Confirming the shared folders problem, see also ​here and ​here.

As shown in these and in the previous links, the problem seems related to dkms.

Should be fixed some release ago. Please check with the latest release 2.2.2 and re-open if necessary.
