Linux – How to share files between Linux and Windows

You should try rsync instead of cp: rsync -avz linux_path /mnt/windows_share/ and crontab instead of the perl loop: crontab -e and add the following line to it:

* * * * * rsync -avz linux_path /mnt/windows_share/

It's going to be executed every minute, and if that's an option in your case, it's more robust than the while loop.

I don't believe this is possible using Windows guests. I usually setup a Samba server on the Linux KVM host and then share a folder out using that to my KVM guests.

Filesystem Passthrough

The documentation on sharing a KVM host's directory with the KVM guests (Linux) is available here on the virt-manager website. The page is titled: Example Sharing Host files with the Guest.

Setting up Samba

The linux-kvm website also contains directions for setting up Samba. That documentation is available here, titled: Tip: How you can share files on your Linux Host with a Windows Guest using Samba.
