Commit Message

Cleber Rosa July 13, 2021, 9:19 p.m. UTC 
Logs can be very important to debug issues, and currently QEMUMachine
instances will remove logs that are created under the temporary
directories.

With this change, the stdout and stderr generated by the QEMU process
started by QEMUMachine will always be kept along the test results
directory.
