For fun I thought I'd try this on the autobuilder: https://autobuilder.yoctoproject.org/typhoon/#/builders/83/builds/1748 Looks like we may need to use importlib to import the qmp module as otherwise oe-selftest can't launch (and the qmp module may not be installed yet). I didn't wade through all the errors, just the oe-selftest one. I also noticed warnings from builds that did work. Cheers, Richard
