+ qemu.run_serial('cat /proc/cpuinfo')
+
+ Args:
+ pn (str): (image) recipe to run on
+ ssh (boolean): whether or not to enable SSH (network access)
+ runqemuparams (str): space-separated list of params to pass to 'runqemu' script (like 'nographics', 'ovmf', etc.)
+ image_fstype (str): IMAGE_FSTYPE to use
+ launch_cmd (str): directly run this command and bypass automatic runqemu parameter generation
+ overrides (dict): dict of "'<bitbake-variable>': value" pairs that allows overriding bitbake variables
