this is samba 3.4.7, on Ubuntu 10.4. and the guest is Windows XP, latest update.

another samba? i dont understand. i mean i am running smbd on the
host, and that is the only samba i run.
if i stop that, how can the guest still see the samba folder?

or do you mean that there is internal samba built-in inside Qemu, and
Samba on the host must be off?
that doesnt seem so, because ./configure always looks for the smbd at
compilation process.
