Hi Steve, nice writeup and scripts. For communication between your
host/externally and guest you can also use ssh and scp:

Add to qemu-system-x86_64 commandline:
-net user,hostfwd=tcp::5556-:22

Install ssh server on both host and guest.

ssh access to guest:
>From host: ssh -p 5556 localhost
>From external: ssh -p 5556 <your_host_ip_address>


File copy to guest:
>From host:

scp -p -P5556 path/file_on_host localhost:path/file_on_guest
>From external:

scp -p -P5556 path/file <your_host_ip_address>:path/file_on_guest

ssh access from guest:
To host: ssh <your_host_ip_address>
To external: ssh <external_ip_address>

File copy from guest:
To host:
scp path/file_on_guest <your_host_ip_address>:path/file_on_guest
To external:
scp path/file_on_guest <external_ip_address>:path/file_on_guest

>From one guest (guest1:port 5556) to another (guest2:port 5557)

ssh access from guest1 to guest2:
ssh -p5557 <your_host_ip_address>

gateway: 10.0.2.2
File copy from guest2 to guest1:
scp -p -P5567 10.0.2.2:path/file_on_guest2 path/file_on_guest1
