-display egl-headless -vnc 127.0.0.1:544 : Use EGL in a headless mode for graphics rendering. Additionally, a VNC server is enabled on localhost and port 544, allowing remote access to the virtual machine's display. ('-display sdl` is used by Xen)
-device pcie-pci-bridge,id=hvc-bridge,addr=01.2 : Emulate a PCIe to PCI bus with PCI address "01.2". (Needed by Xen)
-device virtio-gpu-gl-pci,id=gpu0,xres=720,yres=1280 : Enable virgl GPU mode (host rendering). (Needed by Xen)
-chardev file,id=serial0,path=/home/leoy/Dev2/aosp_cuttlefish_test/cf/cuttlefish/instances/cvd-1/internal/kernel-log-pipe,append=on -serial chardev:serial0 : Create virtual serial device and bind it to the local pipe kernel-log-pipe.
-chardev file,id=hvc0,path=/home/leoy/Dev2/aosp_cuttlefish_test/cf/cuttlefish/instances/cvd-1/internal/kernel-log-pipe,append=on -device virtio-serial-pci-non-transitional,max_ports=1,id=virtio-serial0,bus=hvc-bridge,addr=01 -device virtconsole,bus=virtio-serial0.0,chardev=hvc0 : Create a hypervisor virtual console and attached to local pipe.
Cuttlefish creates HVC 0~15. Except HVC 14 and 15 are not used, other HVCs are bound with the pipes on the host and works as communication channel with the backend program on host. (HVC0 is needed by Xen)
