Changes

For the RNG tests, set the log level to INFO instead of DEBUG. The virtio-rng device does output a lot of DEBUG information, and that can add overhead and make some of our perf tests fail.

@pb8o pb8o changed the title Test rng decrease logging Decrease logging in test_rng tests May 10, 2024
The RNG device can output a lot of DEBUG messages, which adds overhead
and can impact the performance of the rate limiter at high rates and
thus cause the test to fail.

Reduce the logging for this test from DEBUG to INFO.
