Friends
I am starting from first principles and following Yocto Project Quick Build.
I am at the step: Simulate Your Image Using QEMU:
I am unfamiliar with qemu. But it has started up (I watched it spin its
wheels in top) but there is nothing to show for it.
I am running in a Debian Bullseye LXC container as I have had trouble
building Yocto builds in Bookworm. Was that a bad decision?
I am unsure if I have failed or succeeded!
What I see in my terminal is:
runqemu - INFO - Running MACHINE=qemux86-64 bitbake -e ...
runqemu - INFO - Continuing with the following parameters:
KERNEL: [/home/yocto/poky/build/tmp/deploy/images/qemux86-64/bzImage]

You should be able to ssh to root@192.168.7.2

include a SSH server?
