ros
Cannot run ros-image-core
Describe the bug Once ros-image-core is built according to your instructions, it fails to run
To Reproduce I am building for MACHINE qemux86 (originally I made a mistake and built it for qemux86-64. After that I checked it is not supported by ros-image-core. Still the same error appeared) I used ros1-melodic-dunfell.mcf
Build Configuration:
BB_VERSION = "1.46.0"

In your instructions, you did not specify how to run the image so I did
runqemu qemux86 ros-image-core
runqemu - INFO - Running MACHINE=qemux86 bitbake -e ...
runqemu - ERROR - Failed to find /opt/yocto/ros_workspace/tmp/deploy/images/qemux86/ros-image-core-qemux86.qemuboot.conf (wrong image name or BSP does not support running under qemu?).

If more info from a particular log is needed please specify.
The error clearly indicates it is looking for the file opt/yocto/ros_workspace/tmp/deploy/images/qemux86/ros-image-core-qemux86.qemuboot.conf
This file does not exist. Instead
ls tmp/deploy/images/qemux86/

As you can see the file is ros-image-core-melodic-qemux86-20220125001225.qemuboot.conf or ros-image-core-melodic-qemux86.qemuboot.conf
Expected behavior I expected the image to run like normal qemux86 yocto images do. I don't know (it is not clearly explained) how to proceed with ros after that but I will experiment
Please advice
Continuing investigating the problem, even though I built the image as
bitbake -k ros-image-core
I found strangely that I can run the image doing
runqemu -d qemux86 ros-image-core-melodic
Doing that, the problem above does not happen but instead I got another problem
runqemu -d qemux86 ros-image-core-melodic

Apparently now, the problem is when setting the network tap??
I found that ip was not installed, so I did
sudo apt update sudo apt install iproute2
with that, I could finally run the image.
Now I get a console that says:

qemux86 login:
What should I use as login? (and password if any??)
OLD not valid anymore Disregard from here ~~advance a little but get a new error
