No HOWTO but I did give you the command. In a poky checkout run: oe-selftest -r runqemu.RunqemuTests.test_boot_deploy which runs a single test that fails (setup DL_DIR/SSTATE_MIRRORS first to speed it up a bit). It may tell you to clear SANITY_TESTED_DISTROS, I think it auto adds meta-selftest now. You may also need to set DISPLAY to something (e.g. a dummy vncserver). Not sure what is different about the serial qemu is using verses your own tests... > > We may also need to backport the defconfig change back to the older > > releases so we don't get the hangs in those builds either... > Not a problem either.
