The unit tests are tiny guest operating systems that generally execute
only tens of lines of C and assembler test code in order to obtain its
PASS/FAIL result. Unit tests provide KVM and virt hardware functional
testing by targeting the features through minimal implementations of
their use per the hardware specification. The simplicity of unit tests
make them easy to verify they are correct, easy to maintain, and easy
to use in timing measurements. Unit tests are also often used for
quick and dirty bug reproducers. The reproducers may then be kept as
regression tests. It's strongly encouraged that patches implementing
new KVM features are submitted with accompanying unit tests.

+	  kvm-unit-tests is a project as old as KVM. As its name suggests,
+	  it's purpose is to provide unit tests for KVM. The unit tests are tiny
+	  guest operating systems that generally execute only tens of lines of C
+	  and assembler test code in order to obtain its PASS/FAIL result. Unit
+	  tests provide KVM and virt hardware functional testing by targeting
+	  the features through minimal implementations of their use per the
+	  hardware specification. The simplicity of unit tests make them easy to
+	  verify they are correct, easy to maintain, and easy to use in timing
+	  measurements. Unit tests are also often used for quick and dirty bug
+	  reproducers. The reproducers may then be kept as regression tests.
+	  It's strongly encouraged that patches implementing new KVM features
+	  are submitted with accompanying unit tests.
