Yes I find now that this test is of little interest. I will merge it with test_query_polarization as you propose. it is much better as man can see that the > >> + """ >> + This test verifies that QEMU modifies the entitlement change after >> + several guest polarization change requests. >> + >> + :avocado: tags=arch:s390x >> + :avocado: tags=machine:s390-ccw-virtio >> + """ >> + self.kernel_init() >> + self.vm.launch() >> + self.wait_for_console_pattern('no job control') >> + >> + self.system_init() >> + self.check_topology(0, 0, 0, 0, 'medium', False) >> + >> + exec_command(self, 'echo 1 > /sys/devices/system/cpu/dispatching') >> + time.sleep(0.2) > Can you find a way to wait for the event here?

Yes good, I do this Thanks Nina. Regards, Pierre
