gtk initialization failed

[SimonBard]

I started the container with:

docker run -it \
    --device /dev/kvm \
    -p 50922:10022 \
    -v /tmp/.X11-unix:/tmp/.X11-unix \
    -e "DISPLAY=${DISPLAY:-:0.0}" \
    -e GENERATE_UNIQUE=true \
    -e MASTER_PLIST_URL='https://raw.githubusercontent.com/sickcodes/osx-serial-generator/master/config-custom.plist' \
    sickcodes/docker-osx:ventura

Got this error. I was using sickcodes before and the container started, but I was not able to connect via VNC again. I could not set the VNC password as I did not manage to start the qemu console.

Hi, execute container:

docker run -i --device /dev/kvm -p 50922:10022 -p 5999:5999 -p 5900:5900 -p 99:99 -v /tmp/.X11-unix:/tmp/.X11-unix -e "DISPLAY=${DISPLAY:-:0.0}" -e EXTRA="-display none -vnc 0.0.0.0:99,password=on" sickcodes/docker-osx:ventura

After that press Enter in terminal:

QEMU console will be appear.

Type in (qemu)

change vnc password <YOUR_PASSWORD>

---

In your macos vnc connection:

Host: vnc://:5999 Example: vnc://127.0.0.1:5999

I hope it helps!

I hope it helps!

Many thanks! That worked. But when I restart the container, how can I get the qemu console again to set a VNC password? The container somehow stopped during installation, I restarted it with "docker restart zealous_wescoff", but when I do "docker exec -it zealous_wescoff bash", I of course get the bash and I do not know how to set the VNC password then.

I tried to start it with this and got an error:

[arch@12b11851358b OSX-KVM]$ qemu-system-x86_64
gtk initialization failed

Mr. Bard, try access container via bash and run:

qemu-system-x86_64 [...OPTIONS...] -vnc :0,password=on -monitor stdio

-vnc :

NUMBER_PORT is:

0 -> 5900 1 -> 5901 2 -> 5902

Reference: https://www.qemu.org/docs/master/system/vnc-security.html

This command will open the terminal (qemu)

[fillipesouzaaraujo]

Or you can restar container with:

 docker start -ai <CONTAINER_ID>

[SimonBard]

qemu-system-x86_64 [...OPTIONS...] -vnc :0,password=on -monitor stdio

This command will open the terminal (qemu)

Many thanks. But does not work for me:

user@users-iMac-Pro ~ % qemu-system-x86_64  -vnc :0,password=on -monitor stdio
zsh: command not found: qemu-system-x86_64

I tried today again and it did work partially. Unfortunately, it did only open a port on ipv6, not ipv4:

qemu-system-x86_64  -vnc :0,password=on -monitor stdio
QEMU 7.1.0 monitor - type 'help' for more information
(qemu) vnc info
unknown command: 'vnc'
(qemu) info vnc
default:
  Server: :::5900 (ipv6)
    Auth: vnc (Sub: none)
(qemu) change vnc password
Password: *******
