30017는 VNC 포트임. QEMU 에뮬레이터에서 vnc 옵션이 :24117 인데, 이는 30017포트(5900+24117)로 해당 VM의 디스플레이를 VNC로 제공하겠다는 뜻임.

# man qemu-system-x86_64
-vnc display
host:d
TCP connections will only be allowed from host on display d.
By convention the TCP port is 5900+ d. Optionally, host can be omitted
in which case the server will accept connections from any host. |
