Maybe you can add a line in the /etc/fstab file with the user_xattr option ?
#<fs> <mountpoint> <type> <opts> <dump/pass>
vboxsf /mnt/share vboxsf defaults,user_xattr,noatime 0 0
After adding the above line I get in Krusader-root-mode > MountMan > right-click vboxsf > Mount
error unknown mount option 'noatime'
and after modification (user_xattr gives the same error) to
vboxsf /mnt/share vboxsf defaults 0 0
I get
Could not mount device
The reported error was:
/sbin/mount.vboxsf: mounting failed with the error: Protocol error
So I think this line in /etc/fstab isn't going to solve this problem?

This is all with VirtualBox-2.1.4 from the
Repository (Pardus) (because of this I need to change the
wiki page)

Until this moment the
only option is to use
mount -t vboxsf name-of-the-shared-folder /mnt/share -o rw,exec,uid=1000,gid=1000,dev
in a
Root shell-Konsole.And because of this "Root shell-Konsole" you can't put this command in an executable file in /home/username/.kde/Autostart ?
Or is there a setting in f.i. Tasma > System > User manager > username > Groups (translated from Dutch) which make it possible to issue the "mount" command in a User Konsole ?

Any suggestions and idea's are very welcome !!!!!
