I have never even tried getting that to work. I have a manually created

Right, first things first:

1) Do you have firewall (firewalld/iptables) running on the host? Disable
2) Make sure your guest's network interface and your host's br0 interface
have IPs on the same subnet and that they can ping each other.
3) Make sure nmb and smb services are running (nmbd and smbd processes).
4) Create a samba user on the samba server (your host) using smbpasswd.
5) Finally, regarding smb.conf, I'll paste the relevant config later today
when I can get into my similarly configured server.
