QEMU hangs in Docker after the login prompt about poky-container HOT 2 CLOSED

Hi @loic-yvonnet,

Thanks for the extremely easy to follow instructions on reproducing the issue.

PS: I am new to the Yocto project and QEMU. It may not be a good idea to run QEMU on top of a Docker container. I am simply trying to see if I can run everything from a container.

Running qemu inside of the container should work. I reproduced the issue you mentioned, and I think the hang you are seeing is because there is no tty. If you instead tried to run runqemu in the shell started from docker run, I expect it should work.

You could also copy run.sh into workdir and run
docker exec -w /workdir -u pokyuser -it yocto-dev /workdir/run.sh

Unfortunately, I'm unsure if there is a way to use your original command. Because you will likely get the following error if you try using a tty with your original command.

$ sudo docker exec -w /workdir -u pokyuser -it yocto-dev bash < run.sh
the input device is not a TTY

Hi @rewitt1,

Many thanks for your quick answer. I confirm that the following worked for me:

Thanks a lot.
