It looks like the "vnc-version" Dockerfiles will set up an Xvnc server and direct QEMU's output to it, and you can connect to that using a VNC client. The standard version sets up X11 forwarding over SSH and/or you can pass the host's X11 socket and corresponding DISPLAY variable directly to the container. QEMU also has its own built-in remote access capabilities (SPICE and VNC-based) but the former needs guest support.
