This is a Debian/Ubuntu specific samba bug, as explained in comment #7 above. It is not a qemu or kvm bug. The QEMU -smb option works fine in many other distributions, where it can be run as a normal user without special permissions, and with multiple instances on the same machine. This is a fantastic feature, and I hope the samba patch can be fixed so we can support it in Debian/Ubuntu.
Note: I believe the -smb option was recently moved as a sub-option of -net, but it is still supported by QEMU.
