i tested again, and again, but Samba sharing folder never work for me.
meanwhile, my guest can see the folder shared configured in /etc/samba/smb.conf

so this is definitely a bug. perhaps the Samba setting in net/slirp.c is wrong?
the current configuration is like below. i am not experienced with
Samba, so cannot figure out what is wrong.

btw, it seems the Qemu unittest ignore this sharing folder testing?

thanks,
