Debian 9: How to set up Samba-Exchange between QEMU-Host and QEMU-Guest (Windows)?

Question

I want to share a folder on my Debian-host with a Windows-guest. To run the necessary Samba-server I installed the following packages on my host:

• samba
• samba-client

All I know right now is that I only need to add some additional lines with the correct input parameters to the file /etc/samba/smb.conf. I access the guest-VM via virt-manager. Now I found a few notes which state that virt-manager can configure the /etc/samba/smb.conf-file automatically.

Unfortunately I am not sure which command(s) I have to use.

Here is one command with -net user,smb=/absolute/path/to/folder \, but I get the error "Command not found".

Would it end in the same way like adapting the /etc/samba/smb.conf-file by myself?

1. What do I have to type in this file at least?
2. Which permissions does the exchange-folder require?
3. How do I have to configure the Windows-guest for getting access to the mentioned folder (Windows-network is already working)?

Here is an example for the additional section in /etc/samba/smb.conf:

[qemu]
path = /home/user/exchange
comment = my shared folder
guest ok = Yes
inherit acls = Yes
read only = No
browseable = Yes

Solution

The solution for /etc/samba/smb.conf was way more simple than I expected before:

[global]
workgroup = WORKGROUP
security = user
map to guest = Bad User
server string = %h server (Samba, Ubuntu)
dns proxy = No
wins support = Yes
usershare allow guests = Yes
panic action = /usr/share/samba/panic-action %d

[Shared]
comment = Shared Folder for QEMU
path = /home/myusername/Exchange
public = no
browseable = yes
writeable = yes
read only = no
guest ok = yes
force user = myusername

1. Modify the file /etc/samba/smb.conf depending on your needs. In my case (Debian 9), just add the previous lines below the last existent line of the file.

2. Restart Samba via terminal: /etc/init.d/samba restart

3. Mount the now configured shared folder in Windows via "Map Network Drive" --> et voila!
