Berrangé Total execution time with "-m slow" and x86_64 QEMU, drops from 3 minutes 15 seconds, down to 54 seconds. Individual tests drop from 17-20 seconds, down to 3-4 seconds. The cost of this change is that any QOM bugs resulting in the test failure will not be directly associated with the device that caused the failure. The test case is not frequently identifying such bugs though, and the cause is likely easily visible in the patch series that causes the failure. So overall the shorter running time is considered the more important factor. Signed-off-by: Daniel P.
