Nated VM's are on a separate LAN segment of each other, so naturally they can't communicate with each other, except maybe via the internet.

If you want them to connect via your LAN, you should either use bridge or as mavtap.

Besides that the VM's probably have their firewall enabled & you'd have to open the respective port.

To sum up, vsftpd is up and running, KVM and its VMs too. But the VMs can't connect to the ftp server running on their host.
It seems the ftp server is not listening on the KVM network where the VMs are NATed
