How to share a folder between Ubuntu host and a NAT Windows guest with virt-manager?

  • 772

I have a Windows 10 guest running under a Ubuntu 18.04 host with Virt-Manager and KVM. It has NAT connectivity because the host is connected through wi-fi, so I can't access my NAS to share files between guest and host.

I also have installed the Spice Windows Guest Tools, but I can drag-drop only small files like text documents or images and not an entire folder. I tried to share a folder from the host adding a filesystem as squash, but the guest is unable to see it.

How can I share big files between the host and the virtual machine?

Thanks in advance for answers.

    I solved installing the SMB networking protocol with Samba on the host Ubuntu machine.

    On the Win10 guest machine, I created a 'Public' folder with the appropriate permissions and shared it on the network with the following network path: \\<vm-guest-name>\Public.

    On the Ubuntu Linux host machine, I used the 'Connect to server' function and set the following address as a reference: smb://<IP-address-vm-guest>/Public. In my case, the address was 192.168.122.188.

    In the end, I saved the address with the SMB protocol as a bookmark on Nautilus. Now, with a simple click, I can access the shared folder between the host and the virtual machine, and move files of any size.
