for their tests. In order to enable debugging, you can set **V=1**
environment variable. This enables verbose mode for the test and also dumps
the entire log from bios bits and more information in case failure happens.
You can also set **BITS_DEBUG=1** to turn on debug mode. It will enable
verbose logs and also retain the temporary work directory the test used for
you to inspect and run the specific commands manually.
In order to run this test, please perform the following steps from the QEMU
