Opensolaris Virtualbox folder share (mount)

I was trying to share some folders from my windows xp HOST to opensolaris GUEST. But always i got "Operation not applicable to FSType vboxsf".

even after 2 hours of googling i couldn't get the correct answer... And then came my (actually Sun's) mistake to sunlight... because in the virtual box's context help, it is given (look at the image below) that we have to issue "mount -t vboxsf share mount_point" to mount the shared folder.

But it is should NOT be

mount -t vboxsf share mount_point

(Operation not applicable to FSType vboxsf because there is nothing like that but vboxfs)

but it should be

mount -F vboxfs share mount_point

It does make sense vboxfs --> virtualbox filesystem

Atlast happy to have my files accessible in open solaris.

hope someone will land here to get helped.
