Try to be consistent in the spelling of polarization.
You use an s in the title and in the test name below.

I would unite this test with test_query_polarization, they are very similar.

Can you find a way to wait for the event here?

I think it would be good to refactor this snippet into a function.
def guest_set_dispatching(self, dispatching):
exec_command(self, f'echo {dispatching} >
/sys/devices/system/cpu/dispatching')
#TODO wait
exec_command_and_wait_for_pattern(self,
'/bin/cat /sys/devices/system/cpu/dispatching', dispatching)
or similar, you could also put the path into a variable.
