no.

It depends on how you've set up the container's network and where the
guest will connect from.

If your container were using a veth connected to libvirt's virbr0, and
the application is available on port 9999, then your guest could simply

ssh -L 9999:container_ip_addr:9999

and then connect to port 9999 on his local host.  For instance, if you
were opening up vnc on :1 in the container, the container is
192.168.122.89, and your host is 10.0.1.1, then he would do

ssh -L 5951:192.168.122.89:5901 10.0.1.1

and then

vncviewer :51

You can also put the container straight onto your local network, but
the above works with how containers creation is usually shown.
